One of the most important things we can do for landscapes and wildlife in the UK is to connect up trees. The other, I think is to reinstate wetland. When trees are in small, isolated groups, they’re much more vulnerable to natural setbacks and damage from humans. Everything living in the trees may be cut off in tiny islands, with unviable populations. The more scope there is for tree-dwellers to get around between trees, the better their prospects.
Children’s literature may have misled us a bit – Watership Down and The Animals of Farthing Wood show creatures making long journeys to new homes when their old homes are threatened by human ‘development’. For many, there is no moving on. Dormice don’t like putting their little feet on the ground, for reasons best known to themselves. When the trees run out, a dormouse has nowhere to go. Bats are the same – I was involved in hedge replanting some years ago and part of the aim was to give bats a wider range and thus better prospects. Where the hedge stops, the bat stops.
Recently I wrote about plans to develop a Northern Forest, and I was sceptical about government involvement – because I always am. Politicians are prone to greenwash, and most seem to have no grasp of what a wood is or how it works. However, as The Woodland Trust are heavily involved in this project, there are things I feel confident will happen, because there are things The Woodland Trust normally does. I’ve been a supporter for more than a decade.
One of the surprising things I’ve learned from following the work of The Woodland Trust is how long you get to restore ancient woodlands. If land can be re-treed within fifty years, there’s enough surviving material in the soil for ancient woodland to re-establish itself. That makes a world of difference. No doubt sites where this could happen will be a real consideration for the Northern Forest.
Woods are pretty good at extending themselves if they are allowed to get on with it. One of the things The Woodland Trust normally does is to buy land next to ancient woodlands and just allows the wood to come back in. Given half a chance, nature reasserts itself, often what we need is to just stop messing with a landscape and let it return to how it should be.
Connecting up small patches of woodland creates more scope for resident populations to spread out. Again, it’s often just a case of getting things started and letting wild things sort themselves out. Tree planting can be a great way to jump-start this, and trees planted to connect existing, established woods won’t take long to develop the true diversity of woodland.
Over on The Woodland Trust website there’s an article that it makes it clear the forest will develop with this kind of thinking in mind. http://www.woodlandtrust.org.uk/blog/2018/01/a-new-northern-forest-beyond-the-headlines/
