FOBP will plan a new series of events related to woodlands over 2022. If you would like to be involved the first meeting is Tuesday 15 February 7pm (Zoom online). Ideas include – family friendly events, woodlands wildlife habitat action, walks and tree names. Please let us have suggestions (email below) or come along to the meeting. The focus is the Southampton Way woodlands running between Wells Way and Southampton Way.
Wild boar, auroch and red deer shaped our ancient woodlands. They grazed on the saplings that sprung up in the clearings caused by falling trees and kept the soil open to the sky. Wildflowers and berries thrived in the sunshine attracting more wildlife. Stone-age hunters found it profitable to hunt where the animals gathered and were able to keep the clearings open using flint axes. Later on, Bronze age people developed the clearings into places to cultivate rough pasture and crops.*
A completely closed canopy is poor in biodiversity as without sunlight, there will be no plants for forage on the woodland floor. The only insects to be found will be those that feed on decaying leaf litter and their predators. The mighty English Oak will not grow here, their seedlings grow best in more open conditions, often under the protection of a Blackberry thicket. ‘The thorn is mother to the Oak.’ When you find an Oak tree in the middle of a wood, it was there first, other trees grew around it.
Throughout the many centuries since, under-woodsmen have harvested the underwood, taking Hazel, Ash and Chestnut to make hurdles, fences, rustic furniture, firewood and charcoal. The standards, Oak and Elm were left to grow on into timber for ship and house building or to become veteran trees. Felling all the underwood may seem like vandalism, but letting the light in regenerates the woodland as the trees quickly re-grow.
The woodland in Burgess Park West is a young Broad Leaf woodland, planted to imitate ancient woodland, but it will be many decades before it develops veteran trees and the complex wildlife that they support. Similarly, with the plants that indicate ancient woodland – Wood anemone, Herb Paris, Twayblade, Purple Orchid, They need deep, moist, leaf mould interlaced with fungal mycelium and soil micro-organisms to grow in.
Sunshine is a vital agent. In a coppiced woodland, sections of the woodland called Coups are cut every 7-12 years in rotation. Under this system, there are always young tree shoots within the reach of grazing animals somewhere in the woods. Other trees and plants are mature enough to produce nuts and berries to feed animals such as dormice. Somewhere in the wood, areas of thick scrub will have sprung up into a site where nightingales can nest. Full exposure to sunlight every decade is enough to sustain bluebells and other woodland flora. In neglected woods, the flora will eventually be shaded out along with all the wildlife it supports.
Coppicing is hard work and under woodsmen a rare breed. In Blean Woods near Canterbury, things are going full circle and European Bison are being re-introduced to look after the woods. Unfortunately, natural habitats are becoming more fragmented by roads and buildings, so it will take a lot of changes to make it possible for native mammals like the hedgehog or the wild boar to return to this bit of London. The plants and trees that have lasted with us into the 21st Century have adapted to our ancient methods of managing the land and to the animals that live on it. But, they can’t keep up with our present rate of change and we run the risk of destroying these beautiful habitats if we don’t understand and fight for what it takes to keep them alive.
