Connecting up trees

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/

The Northern Forest

The Woodland Trust, alongside The Community Forest Trust are undertaking to plant 50 million trees over 25 years to create a forest in the North of England. There’s details and a map on this website – https://www.woodlandtrust.org.uk/blog/2018/01/new-northern-forest/

The government are investing £5.7 million in this scheme. However, it doesn’t let them off the hook for loss of ancient forests elsewhere. It concerns me that politicians don’t seem to grasp what a wood actually is. A wood is more than just planting some trees. If you plant trees in what was previously a field, unless that field was itself ancient woodland within the last fifty years, you probably just get trees in a field. You don’t get a wood. If your field is right next to an established wood, this can also work. A woodland is also the low to the ground plants, the fungi in the soil, the birds, insects, animals. You can’t offset the cutting down of ancient woodland.

I’ve seen trees planted in fields, and they do not feel like woods. They are missing much of what makes a wood into a wood.

Given the scale of The Northern Forest it is clearly going to have sections next to existing woods, allowing the expansion of habitat for woodland plants and creatures. With the twenty five year time scale, there’s every reason to think this can be done in a way that expands existing woodland, rather than just sticking trees in fields.

I’m excited to see people in the UK talking about tree planting as a way to deal with flooding. We send experts to developing countries to tell them to grow trees on high ground to better manage rainwater, but in the UK too much of our high ground has grouse moors on it. I wonder how much land currently wasted as grouse moors will be allowed to return to a more natural condition in the areas where this is happening. The forest will surround Manchester, location of the infamous grouse moor in protest song ‘I’m a rambler’.

Articles about the project talk about improvements to air quality and to the mental health of people living in cities that the forest will embrace. This is good in many ways, but it is not the answer to either air quality or the current crisis in mental health. We need to cut pollution to improve air quality. We need to deal with causes of anxiety and stress to solve mental health problems (excellent article here – https://www.theguardian.com/society/2018/jan/07/is-everything-you-think-you-know-about-depression-wrong-johann-hari-lost-connections) And yes, tree planting is a good answer to excess rain, but we need to do more than tree planting to deal with the climate crisis causing the excess rain in the first place.

While I am always going to be in favour of tree planting, my worry is that this will be used by politicians as a way of saying they are dealing with issues. It could be a big PR and greenwashing exercise if we aren’t careful. It does not substitute for affordable public transport, reducing air pollution, dealing with an increasingly toxic work culture or tackling the root causes of climate change. Even planting 50 million trees in the UK (which sounds like a lot, I know) does not give us the freedom to carry on exactly as we are.
