Making meadows part 2 

Albany Road seed sowing experiment

As described in my previous blog, we have been experimenting with grass cutting in various locations around Burgess Park, to see which wild plants would emerge over time and how much wildlife would be attracted. We will focus on these areas in the next blog, and discuss the best approaches to maintaining meadow areas and what machinery to use. But, before we did any of this, we experimented with a much larger area of short grass between the three west side mounds and Albany Road. The original plan was just to try and reseed the north banks of the nearby mounds themselves with a more attractive range of plants than the ‘weeds’ that had quickly outgrown the original James Hitchmough prairie planting on these newly built slopes. Previous head gardener Oliver Miller had already experimented with sowing certain seeds, and had the greatest success with a mass sowing of Honesty (Lunaria annua), as well as trying out various other plants.

The previous sowing of Lunaria annua (honesty) with the beautiful lilac flowers contrasting nicely with James Hitchmough’s acid lime marsh spurge (Euphorbia palustris) and light blue quamash (Camassia ssp). The honesty has faded over time with more vigorous plants talking over but it is still present in smaller quantities. 

I knew that with the huge seed bank of fast-spreading wild plants already taking over, and with problems with the steepness, dryness and poor soil structure of the bank itself, that any reseeding would have limited success. James Hitchmough kindly visited a few times, and came up with plan to remove all the weeds between the too widely spaced original plants, before a mass sowing of a special cultivar of Deschampsia cespitosa (tufted hair grass) to fill in the gaps with an attractive ornamental grass with sufficient biomass to outcompete all the weeds. This was a clever idea and would have made the banks much more attractive and consistent looking. But I think when James visited, whilst the banks still looked very much in control, probably because we’d just strimmed between all the remaining plants, there was a huge seed bank of weeds already in the soil. The steep banks, with their increasingly thin covering of sugar beet top soil above a harder pan of soil and rubble from the old park, would be a hard location to establish a successfully thick sowing of grass without some kind irrigation and I think, a lot of spraying would have had to be done, along with good luck with the weather. It turns out that we had some very hot and dry periods over the next several years.

We used James’s Deschampsia, but also selected the seed of a much wider variety of native plants as well. I also decided to spread the seed over a much wider area, to strip back, weed and over sow the banks themselves, but also to try and turn the whole space between the slopes and Albany Road into a more natural space, with much more habitat for wildlife.

I wanted to re-contextualise what was seen as an over ambitious prairie slope that had totally failed, and redefine it as a success for wildlife and the park, with the bank becoming a mix of James’s interesting original plants, plus wildflowers and grasses. James, I think, just came up with an excellent plant list for these slopes. The problem was the LDA design was over-ambitious; the banks were too steep and huge to be successfully maintained as designed. A wilder, less intensive approach was more realistic — a new area for habitat and a softer, more attractive space. Rather than an angular triangle of ‘failed’ planting with just short grass at its base, a continuation of wildness from bank to road with grass paths to walk though would make the increasing wildness of the bank itself much more appropriate and suit the space better. I also guess that perhaps there was once a meadow somewhere along this fence line at some point before the park was rebuilt … there are pretty metal butterfly posts in places, a certain distance from the fence, that perhaps defined some wilder area, so it was nice to return the dull lawn to a meadow if that was the case. 

Many thanks for the council letting me do this; they could have easily insisted that this reseeding was against our obligations to cut the grass around the mounds short, but instead let me proceed with the experiments as I wished. The council showed patience and understanding to allow this area and the nearby banks to become a much more useful habitat as well as being more sustainable to maintain.

The area in winter before we started work. Some lime trees had already been planted by Southwark and we planted a dozen damson trees ourselves. Many more interesting trees had since been planted by the development team, including rare oaks on dwarfing rootstocks, and even Canary Island pines. A few years later we also did two plantings of native whips to try to create a wall of native shrubs along the fenceline. These included wild and cultivated privet, yew, hazel, dogwoods, holly, spindle bushes, blackthorn, wild roses, hawthorn, and cultivars and wild Scotch broom.
A newly prepared area for sowing along Albany Road. I did initially spray off the grass in the flat areas above. I would have rather stripped the turf layer (also removing the most nutrient rich soil at the surface) or simply had a cultivator powerful enough to break through the turf and cultivate the soil. But I did most of the work myself, and I simply didn’t have the machinery or people-power to remove 1000s of m2 of turf and had nowhere to put the giant mound of turf that would’ve been created. I felt in this case, a single spray was justified, to create a much more sustainable and wild area longer term. I also had to cultivate this huge space with a single hand-pushed cultivator to sow the seed and could only do this with bare soil. The concept was to remove the existing turf and then sow a wide range of wild seed, both wildflowers and a wider mixture of native grasses suitable for clay, to see what established, but also to see what pre- existing seed in the soil under the turf would germinate, and what mix of plants would eventually establish, as time progressed, with the soil below unchanged. The banks themselves we heavily weeded and cultivated as best as we could. Here we planned to sow James Hitchmough’s grass and a selection from the other seed that might establish on the increasingly poor and often dry soil of the steep slopes. 

We used a wide range of seeds, starting the flat areas with cornfield annuals for colour in the first few years.

I was interested in how long the cornfield annuals would persist without re-cultivation each year. The answer is about 2-3 years though we still get odd plants germinating where the grass is less thick. The cornfield annuals used were field poppy (Papaver rhoeas), field marigold (Glebionis segetum), cornflower (Centaurea cyanus) and corncockle (Agrostemma githago). I expected these to be the first flowers we saw but nature had other ideas!

After all the hard work, but nature knows best! A great mass of false chamomile (Tripleurospermum inodorum) appears first. The seed of this small annual plant must’ve lain dormant for many years and is in flower already just as the cornfield annuals began to appear. To maintain the meadow as a mix of false chamomile and corn flowers would’ve been lovely but would have involved re-cultivating the soil as soon as these plants went to seed and topping up the cornfield flower seed every few years.
The field poppies appear and the meadow  looks very English! I was hoping if we planted enough poppies some would persist over time, but again they want re-cultivated soil and a decent period of cold in winter to break seed dormancy. We had a few very mild winters after this point and no poppies returned. Hitchmough’s oriental poppies (Papaver orientalis) on the nearby banks on the other hand still appear but are rather engulfed by more vigorous native plants. Here some  enthusiastic students studying at Walworth Garden through Bankside Open Spaces Trust are removing seedlings of certain more invasive plants that we initially (and naively!) thought could be controlled by weeding out.
Cornfield annuals are one of the main plants we have lost from our countryside meadows and rely on a cycle of yearly plowing to grow alongside crops such as wheat. They are mainly kept in existence these days by various excellent wildflower seed-selling companies. Unfortunately, to keep them growing in our meadows, we would need to re-cultivate the soil every few years and top up the seed. But for several hundred quid spent every few years, we could have a few of these large areas of very colourful and densely spaced flowers, that look more like the ‘ideal’ meadow people desire. In this case, we wanted some initial colour (and I hoped the council would be impressed and allow us to do more cornfield meadows in the future!) and for the cornflowers to give some initial shelter to the perennial wildflowers and grasses that we had also sown. In the foreground, one of Hitchmough’s west-facing banks, designed to look a bit like the meadows of central Europe, with Carthusian dianthus in flower (Dianthus carthusianorum).
Poppies on mass looking wonderful in the spring sun. Unfortunately, they totally vanished by the following year, though the cornfield marigolds and cornflowers around the margins persisted for a few more years. We also planted the beautiful sky blue flowered borage, which is starting to emerge in the right of the photo.

As for the rest of the seed, we chose native wildflower and grass seed hopefully suitable for the local conditions, depending on what was affordable and available. Many species I would have liked to have used were either unavailable or unaffordable in sufficient quantities. I would have liked to have used different suppliers to have a broader range of seed, including from the European suppliers Jelitto (https://www.jelitto.com/) but budget constraints meant we went with the excellent Naturescape (https://www.naturescape.co.uk/).

Perhaps a better choice would have been Emorsgate seeds (https://wildseed.co.uk/), simply as they are located closer to London, meaning their seed would be more adapted to local conditions. The wonderful new, low nutrient meadow on the west side used Emorsgate and has a fabulous variety of plants. I unfortunately had no budget to replace all the soil with a low nutrient alternative.

The seed we used included:

Achillea millefolium (yarrow) 
Agrimmonia eupatorium (agrimony) 
Borago officinalis (borage) 
Centaurea nigra (knapweed) 
Centaurea scabiosa (greater knapweed) 
Daucus carrota (wild carrot) 
Dipascus fullonum (teasel) 
Gallium album (hedge bedstraw) 
Gallium verum (ladies bedstraw) 
Hypericum perforatum (perforate St John’s wort)
Leucanthemum vulgare (ox-eye daisy) 
Pastinaca sativa (wild parsnip) 
Plantago lanceolata (ribwort plantain) 
Silene dioica (red campion) 
Silene vulgaris (bladder campion) 
Reseda lutea (wild mignonette) 
Trifolium repens (white clover) 
Verbascum nigrum (dark mullein) 
Vicia sativa (common vetch)

Clay soil wild grasses mix:

Agrostis capillaris (common bent)
Alopecurus pratensis (meadow foxtail) 
Anthoxanthum odoratum (sweet vernal grass)
Briza media (quaking grass)
Cynosurus cristatus (crested dogstail)
Festuca rubra ssp. commutata (Chewing’s fescue)
Festuca rubra ssp litoralis (Slender red fescue)
Hordeum secalinum (meadow barley)
Poa pratensis (smooth stalked meadow grass)
Trisetum flavescens (yellow oat grass)
Festuca ovina (sheep’s fescue) 

James Hitchmough’s generously donated Deschampia for the north banks of the mounds

General clay meadow mix 80/20 mix (80% grasses to 20% flowers)
This had a mix of the grasses to the left and the wildlflowers above plus:

Geranium pratense (meadow cranesbill)
Knautia arvensis (field scabious)
Leontodon hispidus (rough hawkbit)
Lathyrus pratensis (meadow vetchling)
Lychnis flos-cuculi (ragged robin)
Primula veris (cowslip)
Prunella vulgaris (self heal)
Rhinanthus minor (yellow rattle)
Rumex acetosa (common sorrel)
Stachys officinalis (betony)
Tragopogon pratensis (goats beard)
Trifolium pratense (red clover)
(very little of this last list actually germinated)

The seed suppliers have developed great knowledge in terms of the ratios of flowers to grasses so their mixes tend to come in 80/20  or 90/10 grass to flower ratios. But we wanted to just throw down as much flower seed as possible, in the hope that more would persist long term. From the results of our sowing, perhaps a simple 80/20 clay wildflower mix would have been more efficient and much cheaper but we hardly spend a fortune. I did, however, find that few of the flowering species in the clay wildflower species mix actually germinated and the individual species seed germinated better. I wish I’d also included large quantities of Lucerne (alfalfa) in the sowing which would have been great for our Holly Blue butterflies, since it is available as a green manure and is very cheap to buy in large quantities but didn’t think to do so at the time. I should have consulted the local wildlife experts before selecting the seed to have identified more species specifically useful to wildlife found in the park. 

Also, compare our well-intentioned but inefficient sowing with Hitchmough’s precise work which can still be seen at St George’s prairie and various other slopes and dips around the park. James compiled a vast database of native and non-native species during his work at the University of Sheffield. He would build a vast array of small seed sowing beds, try different mixes and record the exact proportions of different species emerging. From this he would estimate the ideal ratios of a vast range of seed needed in a specific mix from wild herbaceous plants of the world. 

In comparison with the precise mixes from the seed suppliers, or James’s very scientific approach, we just bought a load of hopefully suitable seed, threw it down and hoped for the best! This meant that for a further two years we had an impressive amount of flowers. The cornfield annuals faded but with the grass still thin much of the other seed emerged. Certain species such as borage, red and bladder campion, hedge and ladies bedstraw, teasels, wild carrot, St John’s wort, ribwort plantain, knapweed, yarrow, salad burnet, the clay grass mix, lesser amounts of vetch and wild mignonette appeared. The rest of the seed didn’t appear at all. We likely didn’t sow at the correct time for all the species, or conditions weren’t suitable for germination, or perhaps some of the seed in the clay wildflower mix wasn’t so fresh or viable. Unfortunately, the Deschampsia also didn’t emerge on the banks. I think there wasn’t enough moisture for it to establish on the dry banks, and the seed was at least a few years old by the time we used it. There was also too much competition from the massive seed bank of wild plants already present and likely from all the other seed I also added.

The second year, but now the beautiful annual borage, and red campion and many other wild plants have replaced the cornfield annuals. In the background a much larger area of red campion on the re-seeded north banks has appeared. This short-lived perennial sustained itself well until we had a few incredibly hot summers which killed it all off. It then struggled to re-establish from whatever seed had fallen as the previous bare and cultivated soil was now a thick sward of grasses and wildflowers better suited to local conditions.
Bladder campion

Forward a few more years and the balance of plants has changed again. Now the campion, borage and some of the other sown wildflowers have slowly reduced to the odd plant here and there, rather than a great but rather artificial, wall of colour. The soil and climactic conditions clearly aren’t suitable for large quantities of these plants to persist over time. It was a lovely and colourful experiment but longer term, nature will have its way. Clay soil once firm is not very friable so many seeds can’t get into the soil to germinate, or successfully germinate if they do, and most importantly, the clay soil holds onto nutrients so the grasses thicken up over time giving less space for the flowers, as well as forming a barrier to the seed reaching the soil in the first place. Despite us cutting and raking up much of the hay, the range of plants is slowly reverting back to plants that can handle the compacted but rich and quite heavy soil, that can compete with the thick grass and also that can complete their life cycles despite the incredibly hot and dry summers we increasingly have in London.

The grasses are increasingly thick and varied. I still need to try to identify all the species of grass present, what came up from what was sown, and what has appeared from seed already in the soil or blown in by the wind. My eyesight is increasingly poor and the grasses all look very similar without precise or patient enough identification skills!

Summer 2023. Despite cutting low and collecting the cuttings pretty thoroughly each year the balance of plants has changed again. There is much thicker grass but still a large amount of flowers. There are more trees and those planted have hugely increased in size. These will increasingly suck away some of the moisture for the meadow itself, but will have other benefits such as capturing large amounts of carbon dioxide and concealing the road and some of the fast-growing buildings beyond. There is some of the best suited seed of what was sown still appearing, but also copious seed in the soil germinating more suited to the local conditions. Notable plants include chicory (Chicorium intybus), charlock (Synapsis arvensis) and wild carrot (Daucus carrota). The wild carrot was sown and the chicory has quickly spread from the south banks of the mounds. The charlock (a member of the mustard family) is common in London, but is more of an initial coloniser and prefers thin grass or disturbed ground and is slowly pushed out as the grass thickens.
A thick tangle of wild carrot, chicory, and charlock, summer 2023. These are some of the wild flowers suitable for our site. We can start to look at these plants and think about why they are suitable. The chicory and wild carrot has a taproot that can grow under the thick grass to find moisture and nutrients. The small bullet like seeds of chicory seem to be able to find their way through the grass to the soil, which it needs to do to persist as it is biennial. Wild carrot also lasts for two years, but again somehow its copious tiny, bristly seeds also find their way back to the soil. 

We currently have a large amount of flowers and the meadow isn’t too high to problematically block sight lines and, for example, attract too much anti-social behaviour. The soil in this area doesn’t yet have such a high percentage of seed from taller more invasive plants that our more established wild areas in the east of the park have. The various banks of the nearby mounds are also full of wildflowers that can now possibly spread to this new area of meadow. The main one so far is chicory. I was hopeful that some of Hitchmough’s plants from nearby banks would also spread into this area, so, for example, we collected vast quantities of aster seed a few years ago and spread it through the whole area to try to extend the meadow’s flowering season, but none has emerged. Brockwell Bake and ancient wheat expert Andy Forbes also tried to establish a few old varieties of wheat, including one with an attractive, purplish seed head. These patches did great in the first year, but didn’t resow themselves the following year. 

But our work isn’t done, nature has further plans for our meadow, and we have reached the most challenging stage of maintenance. Ideally we would like to keep the meadow as it is at this stage, but there are many more vigorous and potentially problematic plants that want to establish and outcompete the plants currently growing. 

One particularly significant plant is mallow (Malva sylvestris). This year this species has begun to dominate in places. It has pretty purple flowers, but not a particularly attractive structure once it is fully grown, and it both spreads by roots very quickly to form dense clumps as well as dropping copious seed. This would be difficult to eradicate even by spraying; this plant is here to stay. The only way I can think to control it is to cut down and remove all the seed laden stems once it has finished flowering to limit its further spread. But it is a very useful plant for wildlife (and for people foraging for edible leaves in the park).

Mallow (Malva sylvestris) growing through Hitchmough’s azure asters on a west bank of the mounds, close to our new meadow. The meadow itself has increasingly huge amounts of this pretty-flowered but rather ugly-shaped species. It was there all along in remaining root fragments and seed in the soil and is now quickly dominating. 

But there are a great array of taller and even more problematic plants that want to establish in our meadow and re-seeded banks. These include: 

Gallium aparine (cleavers) forms a great mat of foliage over other plants which is hard to remove and looks a mess, though it creates habitat and keeps the soil below moist. We have given up trying to remove this as it comes up en masse in spring, but luckily then withers and completely fades away by early summer. 

Calystegia sepium (Hedge bindweed) Most gardeners will be well aware of the joys of trying to control bindweed. It does seem to prefer richer soil and flowerbeds and hasn’t spread so fast on the three north banks as I worried it would, though it is a problem in places, as is Convolvulus arvensis (hedge bindweed). On another north bank next to the car park, we worked incredibly hard to remulch the failing slope and replant densely but after a few years where it looked really good, a great carpet of bindweed spread quickly through the thick mulch and totally ruined our work. We are now trying to work out how to get rid of it without killing everything else.

Urtica dioica (stinging nettle). This is a great wildlife plant and we have allowed large clumps to establish on the slopes for certain butterflies. But now it is also appearing in the flat areas of meadow, making it less attractive, more stingy for humans and potentially outcompeting the plants we have already described. Hopefully, it will be kept in check by the thick grass and many other plants competing for nutrients but it is hard to eradicate. 

Cirsium arvense (creeping thistle) Like stinging nettle, this spreads by a great network of roots and is very difficult to kill without herbicide. The roots run deep with this plant. It has formed large, tall clumps in various places along the various slopes and has appeared at the far end of the meadow. It has also established in great clumps in places on the new, low nutrient meadow, due to the roots running deeper than the soil replaced. Again it is used by our wildlife including butterflies, but it’s not very pleasant to try and walk through a great clump of it or to have whole meadows turn to thickets of thistles. 

Arctium lappa (greater burdock) Another wonderful wild plant for wildlife and medicinally for us, with an impressive structure, pretty little thistle like flowers and giant leaves with great potential to use as a mulch. But it has the most irritatingly spiky and clingy seed which it produces in massive quantities, a massive root system that is impossible to remove, and can grow two metres high. It emerged in a few places on the second north bank, and quickly became a 50m2 thicket, shading out all the plants below. All we can really do without chemicals is cut it down once it is seeding and remove all the seed and cuttings, ideally using the cuttings as a mulching material elsewhere. 

Artemisia vulgaris (mugwort), similar to burdock, another useful medicinal plant with an impressive structure, but also very tall and very quickly spreading into huge clumps. 

Rumex obtusifolius (broad leaved dock). Another wonderful plant for wildlife but again, grows very tall and can produce 7,000 seeds on one plant. I like the rusty-coloured stems in autumn, but it is another plant that can grow to head height and quickly outcompete other plants. Again, I think the only solution is to remove enough of the stems before all the seed drops each year. 

Conium maculatum (hemlock). Another giant, again useful for pollinators with its copious and attractive white umbel flowers, But a very poisonous plant to us, that will grow into huge tall thickets if not kept in check. Again, all we can do is cut down all the seed laden stems before the seed drops so it doesn’t spread across our new meadow. 

Rubus plicatus (wild blackberry / bramble). Bramble is the most difficult plant to deal with in the park though, of course, provides copious fruit for us and wildlife as well as habitat. But one plant can send out multiple giant stems that can each grow several metres in a season. The stem quickly loops back down to the soil. It then scrambles along, often hidden under the herbaceous layer. 

Adventitious roots quickly appear where the nodes on the endless stems are touching the ground. So one plant can easily become 50 plants in a year. The roots themselves also quickly become huge, deep and difficult to remove and also quickly spread through the soil. We are battling to control this plant in all of our meadows and wild areas in the park. 

Bramble is appearing all over the various slopes next to our new meadow. We hack out the roots and remove all the stems as best we can, but longer term, some careful spot spraying may be needed to control it sufficiently if we don’t want the whole park to become a giant thicket of thorns!

Current Level 3 Apprentice Kiran working hard to control great thickets of emerging bramble on the third north bank. This bank was so overgrown with vigorous wild plants, with such poor soil and the Hitchmough plants mostly gone, that we didn’t bother trying to re-sow it. We did, however, add a widely-spaced planting of hawthorn, wayfaring trees, wild roses and butterfly bushes to create more habitat and another layer of canopy on all three north banks. These are sporadically establishing though have failed in places due to summer drought and increasingly poor soil. Below, staff removing dock, burdock and hemlock stems.
A wild, habitat-rich, consistent space that was formally a ‘failed’ bank and dull lawn. You can see a clump of white flowered hemlock on either side of the path. These need cutting down before the seed spreads further once the plant has finished flowering but it is a more natural space than before. On the left, a wide range of grasses, nettles on both sides for butterflies, and on the right a slope covered in Gallium album (hedge bedstraw) provide excellent ground cover and flowers later but also lesser amounts of the undesirable cleavers (Gallium aparine). 

Conclusions made 

So was all this worth it? Roughly £1500 spent on a copious amount of seed and a lot of hard work. 

We now have a diverse, constantly evolving meadow with a broad range of species, both introduced and already present. If it eventually does become too vigorous and overgrown for our recreational space it can always be cut back for a while, but hopefully this won’t be necessary. 

Before, a vast amount of time was pointlessly spent each week with most of the park staff trying to hand weed these giant banks like huge flowerbeds. With so much else to do in the park this simply wasn’t sustainable or realistic, and the banks were quickly returning to wildness however hard we worked. All we were doing by intensively cultivating these banks was preventing them from becoming useful habitats for wildlife. 

For several years we had a wonderful if rather artificially dense display of flowers that evolved over time. 

The formerly large area of short grass would have taken a ride-on mower a whole morning every 3 or 4 weeks to cut. Now it takes me an hour to whizz along the remaining paths once a month. I’ve actually made the paths a certain width, so people walking along them keep them pretty short without any cutting at all. 

But we have a few days of hard work each year cutting and raking the hay to try to remove enough hay and the build up of nutrients, to keep the grass thin enough for plenty of flowers. Increasingly over time, we will also need more time to control by cutting down and removing the seed of the more vigorous, invasive plants. 

Ideally we would cut it twice a year, not just in spring but also late autumn, but this is very difficult with so much other work such as cutting all the other meadows and picking up a vast amount of leaves each year.

Ideally we would have much better machinery than our knackered handful of strimmers and one mower to cut and collect the hay more efficiently and sensitively, but I will talk about this in later blogs. 

I think the experiment also shows that we have the soil we have, the pre-existing seed bank we have and the range of wild plants we have, suitable to local conditions. We can introduce a wider range of wild native plants by sowing seed, but often nature knows best and will try to find its own natural balance of plants over time … So then our job is to gently adjust this balance so it remains suitable for a busy park. 

And the most important thing about this project is wildlife, so has this new meadow been successful at creating more habitat and is more wildlife present? 

I often don’t have enough time to observe, so this is the job of the Southwark biodiversity team, and local ecologists and wildlife experts and enthusiasts to judge. But despite my lack of ecological expertise I can confirm that there is much more wildlife in this space. 

Bees and grasshoppers and many other insects are present in the longer grass, and the now, not constantly disturbed, north banks, are buzzing with life when I walk across them apart from in very hot periods where the plants shrivel and the insect life quickly dwindles. 

I see more butterflies and smaller moths fluttering around this space than before. Hopefully these numbers will increase over time as the range of plants most useful to them increases such as nettles and garlic mustard. 

There are multiple wrens now nesting in the shrubs or in thick patches of tall grass along the slopes. There are groups of sparrows and other small birds foraging for insects and seeds. 

A few weeks ago I saw a jay flying between the trees perhaps thinking about extending its territory. Several times I’ve seen kestrels hovering above the meadow and the slopes of the mounds. I see people foraging for food such as dandelion leaves and roots and mallow leaves or medicinal plants such as mugwort. More people walk though the space. More people sit and relax in the space now it is wilder, with more shelter from the noisy traffic of the nearby road. It would be nice to put some more large logs in this area for seating as the original ones have perished / been eaten by lesser stag beetles. In the next blog I hope to discuss all the other grass cutting experiments we have done more recently and discuss best practices and machinery for maintenance. I will also do a list of the majority of the wildflowers I have found growing in the park.

Many thanks for reading.

Birds of Burgess 2021 Review

Blog: Dave Clark

Writing this in January 2022 the focus of birding interest centres around the lake at Burgess Park. Geese, gulls and cormorants increase their numbers at this time of year as they battle to survive the natural elements and human impositions before the high energy sapping spring arrives. Spring, when the days are longer, spring, when optimism fills the air, spring, when not just the lake but the whole park resonates to the natural sounds and movements of birds. Spring is when the lifestage focus shifts from one of survival to breeding; finding territories, finding partners, building nests, laying eggs and having kids…………well chicks. With this in mind and the short winter days and long nights providing an opportune mental space for human reflection it `s appropriate to mull over and review the multitude of bird highlights that over the 2021 seasons Burgess provided.

Mediterranean Gull - Josep del Hoyo

Eighty five species were seen across the year by twenty two observers who provided hundreds of important records of these sightings. There were twelve different long distant spring migrants recorded, either staying for a few days, using the park as a feeding stepping stone or remaining until summer to breed, nine different species of warbler, seven different species of gulls, five different species of birds of prey, two different flycatchers and a partridge in a pear tree………..ahem, not really,  but a pheasant was indeed seen!

Common Redstart - eBird

Spotted Flycatcher - Saurabh Sawant

However these numbers are pretty, lifeless and unemotive without context. For the true importance of Burgess Park as an avian hotspot and green performer to be understood we should compare these figures and the interest that they have engendered to other green spaces. Eighty five is a tick list that would be expected in more `wilder` and `natural` areas or rural arcadian idylls not in an urban park, indeed in these traditionally more cosmeticized environments forty to fifty species would be a more likely expectation. Neither are these numbers just birders ticks in a little black book or competitive markers but more importantly denote what can be achieved in urban green spaces at a time when 67% of the UK`s bird species are deemed of conservation concern.

These heartening results do not come by chance. Burgess Park has locational advantages; it is not far from Thames and is characterised by superb vistas which allows birds sightlines of the lake and green areas. But it is the considered management and provision of various habitats which are the key factors in attracting the abundance and diversity of birds,  ……scrub, long grass, wild flower meadows, richly planted gardens and ofcourse the important water feature. It is no surprise that many of the rarer species encountered were found in the less sterile environments, environments which we have been institutionalized to believe as rough and unkempt. These pejorative terms mask the positives, we should be thinking rich, diverse and life affirming. Scrub is good is the mantra.

For these birds, several of which are long distance migrants, wintering south of the Sahara, to continue to be attracted, these habitats need to be retained and maintained by diligent management and hard work. Management that does not have dominion but understands that nature is at the apex of importance of any green space.

This gives us an indication of the natural health of our precious green urban space and allows us to understand the changes that occur seasonally within nature. The winter profile of the lake is one of gulls, cormorants and wintering ducks seeking, believe it or not, a warmer climate from their usual surrounds.

Being proximate to the Thames and easy for birds to see from the air, the wide vistas of the park provide a backdrop that allows avian incomers to assess the attractiveness of the lake, with food and safety being the prime instinctual drivers. This winter the lake has continued to provide a home, stopover and feeding station to the usual suspects alongside less common and in a Greater London context, rare species.

The star of the show was a White-fronted goose which quite happily fed and swam with the resident Greylag geese population, gracing us with its rare presence for around a week. White fronts, check out the white patch above the beak in the above photo, migrate to Britain during the winter to escape the bitterness of lcelandic and Russian winters with this particular bird being one of the rarer subspecies which arrives from faraway Siberia to land habitually on our coastal and estuarine environments, a rarity indeed.

Usually seen, if at all, on the large expansive London reservoirs the Goldeneye is a distinctive wintering duck from Scandinavia. A beautiful male appeared later in January for three days and was probably the same individual that appeared for the same duration on the lake before last year`s lock down.

Other ducks of note that have also been seen are the subtly plumaged Gadwall and a long standing male Pochard in all its orange-red headed glory.

On our playing fields, parkland and ponds there is always a winter build up of gulls, and on any one day during this winter there have been up to two hundred Black-headed gulls swooping and swimming at the lake. We commonly make the mistake of perceiving them as seabirds when in fact they are coastal birds and with the Thames so close the route to the coast is only 20 to 30 miles away. Along with Common gull, Herring gull and Lesser black-backed gull the lake has also attracted, on occasion, Britain’s largest gull the Great black-backed gull, a serious beast standing at 70 centimetres it is twice the size of the usuals and five times the weight!

Finally in our water bird list is the Mediterranean gull which pops in and out of Burgess Park. As suggested by their name they are used to a warmer environment and although still rare the general increase in abundance of this bird in Kent coastal areas is a sign of our changing climate. Very similar to the Black-headed gull the white wing tips and droopy beak help discriminate between the two species.

A heartwarming effect of the lake’s success is the notable increase in the number of observers who are recording sightings on the various social media platforms. I’m sure the coming seasons will add to our birding pleasure, and whether casual or serious in our intent there is no doubt in these strange times that the lake and the park are important for our well being. Keep birding!

Burgess goes wild: Gulls

Gulls in winter

by Dave Clark, Ornithologist

The abundance and species of birds change with the seasons and at Burgess Park this is as true as anywhere in the country. Take a special look at the lake during the winter where the number of gulls and cormorants increase.

We commonly call these grey/black and white birds – seagulls – but they are actually coastal and inland birds and consist of several species, look out for these four different birds during the winter:

Black headed Gull: The smallest one – look out for the red bill and legs.
Common Gull: Not as common! as the others, a bit bigger with a white head
Herring Gull: Much bigger with a large yellow beak and pink legs
Lesser Black-backed Gull: Like a Herring Gull but black rather than grey wings and yellow legs
Litter pick volunteers load a rubbish truck

Tackling rubbish behaviour one bottle top at a time

Mother and child at litter pick morning

Litter picks are every Monday morning, 7.30-9.30am and Thursday evening session 6.15-8pm. Both weekly litter-pics continue until the end of September.

FOBP provide litter-picks, gloves and bags or bring your own. Come along to any session, meet-up at Chumleigh Gardens picnic benches.

Our first session was 20 July and between 12 and 20 people have come along at each session, 50 people have done 92 volunteering litter-picking sessions. Some people have come to lots of sessions and others just to one or two but it all helps. Together we’ve picked up bags and bags of rubbish and just as importantly loads of the little stuff that gets missed; bottle tops, cigarette ends, shiny metallic balloon confetti and broken plastic cutlery.

The FOBP litter-pick is helping the park gardeners after the week-end and improving our park for wildlife. With people from the community involved and some stronger messages from the council about the unacceptability of leaving rubbish we hope to make a small difference this summer.

Volunteer collection rubbish

During the summer you can’t have missed the photos and images of rubbish left in open spaces across the country, including Burgess Park. Parks have never been so popular, but for our gardeners it has just meant mountains of rubbish to collect every morning.
With many people complaining about the rubbish Friends of Burgess Park set up a regular weekly litter-pic session. We are so grateful for the fantastic help from Burgess Parkrun and Southwark Good Gym volunteers.

Come and join Burgess Park Team Zero Waste or get in contact if you have any suggestions for reducing litter at friendsofburgesspark@gmail.com.

Postcard people and parks need sunshine

Don’t put Burgess Park in the shade

Burgess Park west (running from Wells Way to Southampton Way) is under threat.
New developments are planned all along the southside of the park on Parkhouse Street.

35-39 Parkhouse view from Burgess Park with planned buildings







Tall developments along Parkhouse Street
will block the sun

The 10 storey high blocks (about 30m) will be north facing and cast long shadows across the park. In the winter mornings the shadows will be over 100m long and reach to the main Surrey Canal path. In the summer, shorter shadows will still reach across the wildlife area, about one third the width of the park.

Overshadowing from multiple buildings* will change the character of the park. It will have a negative impact on green space, biodiversity, and people’s health and well-being.

Postcard back Jan 2020 v2Southwark Council needs to make clear in their planning policy and discussions with developers that they are taking seriously the cumulative impact of tall buildings along the park boundary.

Very little will grow in the deep shade from buildings. Some plants thrive in light shade, but wildflowers and pollinators need full sun throughout the day.

People and parks both need sunshine

Burgess Park west was created in 2018/19 with a £3.5m make-over taking out New Church Road, putting in a playground and extending the wildlife area. The new walkways through the wildlife area are already popular with children, walkers and runners bringing back into use a previously closed-off, no-go area. This is the squeezed middle of the park, less than 200 meters wide, so the extra usable space is really welcome

The wildlife will take a few years to become established. But the evidence from other areas of the park is that the mix of small woodlands, meadows and native bushes attracts and encourages a good mix of plants, insects, butterflies and birds. Sometimes this habitat mix is called scrubland. Often in planning reports it is implied as having little value. That might be the case in places with lots of green space but here in Southwark our patch of green space is important to many, many people.

Inner city green space is vital for people

People who live both nearby and further away use Burgess Park. Since the re-landscaping of 2012, user numbers have gone up and up. It is one of the major parks of the area. As Southwark’s population grows it will be very difficult to make more large, green spaces where children can run freely, play rounders and football. We must look after and keep green spaces for future generations.

Burgess Park has a vital role to play for local people. Around Burgess Park the new Aylesbury area is being built, taller blocks are planned along the Old Kent Road and the new residential developments along Parkhouse Street mean that many more people will use Burgess Park. We want the park to provide high quality green space with different landscapes for people to use and enjoy.

The real value of green spaces for people is easily overlooked

BAME respondents were twice as likely as white respondents to use parks and green spaces for team and individual sports and to meet friends.

Burgess goes wild: Sparrows, Starlings, Whitethroats, Warblers

From Africa to the Old Kent Road

by Dave Clark, Ornithologist

10 years ago I did some bird surveying for the council at Burgess Park and last week I had a revisit. Wow I was impressed! Blown away by the positive changes that have occurred in the interim. 

photo of plants
Burgess Park meadow

Wildflower and meadow areas buzzing and singing with life, amenity grassland merging seamlessy into nature friendly areas. People working out with butterflies dancing around their feet.  No inaptly named so-called ‘eco-zones’, just a park working with nature.  All this in an urban area close to the centre of London.

The beloved Cockney House Sparrow which has lost 60% of its urban population since the 1970s is thriving here, not just picking up scraps from around the cafe but flitting amongst the meadowlands for live food for their hungry chicks.  

photo of bird on a branch

I found at least 30 (last time just a pair) and to put this into some kind of context there are no Sparrows in Peckham Rye Park nor Dulwich Park.  Similarly the Starling population, compared to  other local urban spaces, is abundant. This lovable roguish street urchin of a bird, once so common it was deemed a pest, has suffered 66% losses since the mid-70s and is now a red-listed species, i.e. a species of highest conservation concern.

What was really exciting was finding seven different breeding territories of birds that had flown all the way from Africa. Five male Whitethroats busily displaying amongst the meadows and two Reed Warblers, guess where – in the reeds surrounding the lake. Both of these species travel from the Sahel, a region between the Sahara desert and the Savanna, to breed here in the UK. To find them so close to the centre of London is uncommon and a pleasure. The scratching sound of the Whitethroat and the gurgle of the Reed Warbler is deeply resonant of the exoticism of a faraway continent. Their joyous life affirming songs showing that nature can survive despite what obstacles we throw at it.

Well done, you should be proud. Burgess Park is an example of what can be achieved in an urban inner city area when ecological concerns are placed at the forefront of the agenda and not left at the bottom of the priority pile. Nature does not pick nature reserves. Nature is all around and can flourish with some care and attention. Praise should be given to Greg and his gardening team for being a large part of this environmental success despite having only limited resources and despite having to battle the conflicting interests that public parks bring.

So is this just a nature lover banging on …

Er … nope … the maintenance and improvement of the health of urban green spaces is paramount for all of us not just nature. 80% of us live in cities for a start and we also know that access and proximity to nature is beneficial to our physical and mental well being, reduces stress and reduces crime. By making nature more visible and audible the easier it becomes for people to engage with it.  Engagement with nature not only brings joy but also increases our care for our environment.

We can deny nature but we can’t get away from it, it’s the air we breathe, the food we eat, the water we drink. It’s incumbent on all of us to maintain its health.

Well done again!

Burgess goes wild: Butterflies & Moths

Nature under our noses in Burgess Park

by Simon Saville
Chair of the Surrey & SW London Branch of Butterfly Conservation

I suppose that most people don’t think of butterflies when they think of Burgess Park. But they should! Already this year (by late March) I have seen a Small Tortoiseshell, a Small  White, a couple of Commas and a couple of Brimstones.

Over the past few years, I have spotted no fewer than 16 different types of butterfly in the park. On one spectacular sunny July day, I saw more than 160 butterflies of 10 different species, plus a couple of day-flying moths.

Burgess Park has been managed quite sensitively for wildlife, and there are lots of good places for butterflies. Some of them are shown in this map:

Map of Burgess Park showing where butterfly species have been seen

1 – Elm trees, supporting some very elusive White-letter Hairstreaks
2 – Nature area, being redeveloped. This could become a nature hotspot in a few years’ time
3 – The big mounds, home to the Common Blue butterfly
4 – By St. George’s Way
5 – Grassy area with brambles
6 – South-facing slope
7 – Wooded area north of the lake
8 – Grassy area by the lake
9 – Grassy area and hedges between Waite St and Oakley Place
10 – Glengall Wharf, start of Surrey Canal Walk

The Comma is a harbinger of spring, often seen in April. They spend the winter hibernating as adults and they reappear as soon as the weather warms up. This one was in the wooded area north of the lake – a favoured spot. The caterpillars used to feed on hops, but now have a taste for nettles and this has helped them increase their range and abundance in recent years. 

Photo of a orange, black and white spotted butterfly

The Small Tortoiseshell also hibernates as an adult. This one was spotted in the middle of the Park by some brambles in April. The caterpillars feed on nettles, so it’s important that we don’t tidy the nettles away! We used to see a lot more of these butterflies. Nobody really knows why they have crashed in numbers so quickly.

The big mounds are often teeming with insect life, a result of the many wild flowers present.

Photo of striped moth

The spectacular Jersey Tiger moth can be seen flying in the Park in July and August. This photo is from Kennington, about a mile away. This used to be restricted to the south coast, but is now spreading rapidly. It can be seen all over south London. Because it is colourful and flies by day, it’s often mistaken for a butterfly.Photo of trees in winter

I haven’t seen any Painted Lady, Peacock or Ringlet butterflies in Burgess Park, but I would be surprised if they were not present, as they have been seen at Nunhead Cemetery (3km away). The Painted Lady, which is a migrant species, was also seen at Walworth Garden (1km away). There may be Purple Hairstreaks on the oak trees by Waite Street.

Moths present include: Jersey Tiger, Six Spot Burnet, Burnet Companion, Silver-Y and Sitochroa verticalis.

All this goes to show what a wonderful place Burgess Park is for butterflies. I know that Southwark Council are keen to make it even better.

Butterfly Conservation has started a ‘BIG City Butterflies’ project, supported by the National Lottery Heritage Fund. This aims to get people to engage with the green spaces near them and to discover the wildlife that’s under their noses. We’ll be using Burgess Park as one of our key sites in SW London. It’s early days, but you can read more about Big City Butterflies here.

Crows in trees in Burgess Park
By the Bridge to Nowhere – a murder of crows

A murder of crows
Perhaps, if crows were brightly coloured, they would be loved instead of feared. Part of the Corvid family which includes magpies, ravens, jays and jackdaws they are arguably the most intelligent and fascinating of all birds. I have watched them fly off with a chicken’s egg, wash the salt off a chip in a puddle before eating it and mobbing a fox. Set aside an hour to watch this brilliant documentary which will make you view crows in a whole new light.

We don’t hear so much about acid rain these days, but it’s still there, scrubbing clean the tree trunks of moss and lichen, so a treat to see this.

Photo of tree trunk
Lichen on Horse Chestnut bark near the underpass.

Not one organism, but two, a fungus and an alga that can’t live without each other. The fungus provides the structure and the algae make the sugar. There are many different species of Lichen. It’s not feeding on the tree, but is affected by the acidity of the water running off the bark . You will find Lichen on brick and stone, glass, metal ,leather surfaces too.

Lichen is used to make Litmus paper. Dies are extracted and added to filter paper so that it turns red in acid conditions and blue in alkaline. Some lichens contain Usinic acid which is anti-inflammatory, anti-microbial and attacks cancer cells. Unfortunately, it also damages the liver.

Seed heads

Still some lingering seed heads from last year’s spectacular display in St George’s Gardens. Many seeds have a protective coating and won’t germinate until they have been exposed to frost. This keeps them fresh and hydrated ready to send out new roots into the warm moist spring soil.
