ОглавлениеRewilding site, Kielderhead Nature Reserve.
Kielder wildwood is a wilding project with an especially big ambition. It is a woodland restoration and creation project in its own right, but is also conceived as a means to a much greater goal – that of integrating degrees of restored natural processes across the vast landscape of forest and open land between Whitelee Moor on the Scottish border and the whole of the wider Kielder Forest and Water Park landscape. Indeed, the wider vision is to extend this wilding approach across the Scottish border and to complement the already largely rewilded Border Mires – one of the largest restored peatscapes in England.
Thus, we are working with our partner landowners the Forestry Commission and Kielderhead (cross-border) Committee and others, to make all of the area wilder by degrees, recognising that even within the commercial forestry areas, there are already integrated wild lands, such as impressive riparian corridors. If nothing else, this Kielderhead wildwood concept is ambitious and certainly landscape-scale – more a ‘future proofing’, area-wide approach, than a mere project.
Part of the vision is very much about creating a ‘forest for the future’, a more natural, open montane woodland of mainly native species, with a more complete ecosystem over the longer term. Initially, this will focus on a 94 ha area of the Scaup Burn valley, which will be planted with 39,000 trees over three seasons, all by volunteers.
We recognise we are starting not in prehistory but in the twenty-first century, in a commercially important, working forest context and we have reasonable acceptance of this in species-mix selection, management and establishment techniques.
This vast area of open land runs for over 8,000 ha up to the Scottish border. Today many of the hillsides beyond where plantation forest is still maintained are devoid of trees and, because the blanket bogs on top of the moors are important open landscapes in themselves, tree cover is actively discouraged. Large areas have special conservation designations to protect their special habitats and species, though often such land has the marks of human interference, being prepared long ago for possible forestry use.
The idea is to create ‘future-scape wildwood’, which has elements of species and habitat that thrived in prehistoric times here when the ecosystem was more complete. We aim to plant locally appropriate species such as downy birch and rowan, willow (some of which is already recolonising areas), juniper and many other species.
People are closely involved, despite the area’s remoteness. We started gathering local seed early on, including from rare old pines, growing seedlings with a view to planting to local seed stock. We draw additional inspiration from historic and prehistoric perspectives locally.
One key feature is a group of old Scots pines, the ‘William’s Cleugh Pines’, long thought be possible remnants of ancient or even prehistoric lineage – if true, they would constitute the first confirmed specimens of native English Scots pine.
Genetic work that has been carried out is inconclusive, but nevertheless the possibility remains of Scots pine being a surviving component of prehistoric forests. Evidence of the ancient forests is seen in the peat beds underlying the site and exposed in banksides and the burn – a layer of horizontal forest dated to 7000 bce, including pollen and preserved evidence of pine.
In addition to this, a branch was discovered in the side of the burn that dated to the fourteenth century and clearly exhibited beaver activity! In these historic remains we have perhaps some historical precedent, if we needed it, to develop a restored and more natural ecosystem.
Thus far we have initiated a massive volunteer effort in the middle of nowhere and started the establishment phase – the rewilded landscape is already taking shape, with 7,000 trees planted in the first year. We bid for and won Heritage Lottery funding, which is now enabling staff, volunteer effort and material planting and development of the project. We’ve brought on board world-renowned experts and undertaken micro-propagation from those old pines.
We are also addressing the cultural resonances of this remote part of the Anglo-Scottish landscape, a disputed land for centuries and perhaps also in the future, as border politics have definitely not completely gone away. Allied to the wildwood project we have successfully undertaken the Restoring Ratty project, aiming to restore water voles to the catchment.
What then might the future look like in decades to come? Ecological change is a certainty, natural processes will be restored, more natural and complete ecosystems come into effect and this should include the restoration of absent species.
Despite the very man-made nature of Kielder Forest and Kielder Water, the scale and breadth of wooded and open habitats across the whole area makes for a very natural feel, similar in character to parts of Scandinavia, and it is already surprisingly diverse relative to other areas of the UK.
Kielder already carries significant populations of key species like red squirrel (largest population in England), roe deer, badger, tawny owl, otter, wild goat and now, once again, water vole. Pine marten are recolonising themselves, golden eagle have just been reintroduced over the border and we hope may re-establish. We have osprey and other rare raptors that have come in – and a very wide range of bird, amphibian, reptile, insect and plant species, as expected.
So, in the future it can be envisaged that this rich range of species will be strengthened and extended – and joined, eventually, by beaver and even, perhaps, wildcat and other larger predators and herbivores: judiciously reintroduced after proper inclusive consultation and preparation. Reintroduction of species is only a long-term aim here and not the prime focus of the wildwood and Kielder in these early stages. Habitat restoration and development, though, will tend to lead the way to this.
This is a large, potentially resilient, forest area and, as it becomes more naturalised, will develop a sophisticated ecology. Balanced against this will always be the needs of commercial forest interests and the views of local farmers, and communities who live here and manage large areas nearby for other complementary uses. They too are part of the developing ecology of a ‘Wilder Kielder’.
