It may be as a Druid that your first instinct is to protect trees no matter what. It’s a good instinct, (I would think that, because I do feel it) but at the same time, it helps to understand the historical relationships between people, trees and the landscape.
First up, wood is an amazing material. It is sustainable to use so long as we take only what we need and plant three trees for every tree we cut down. It’s also sustainable to coppice and pollard. Wood is not actually one material, different trees have different properties – alder for example resists water. Venice was built on alder. Wood is durable, beautiful, and effective.
Secondly, if the land has a history of human wood work over thousands of years, then continuing isn’t a bad idea. There are woodland flowers that don’t show up unless patches of woodland are cleared. Small scale, rotational tree coppicing results in a wealth of other wildlife being able to return. Diversity of plants increases insect populations which in turn feed birds and bats… Letting the light in will also help slower growing trees like oaks get started.
What doesn’t work is industrial scale logging. It doesn’t work to cut everything over a large area, especially if you follow through by not even replanting. It doesn’t work to take rare hardwoods out of rainforests, or to put vast monocultures of pine into places pine doesn’t normally grow.
If we are to use wood as a sustainable resource, we have to do it while maintaining the health of the overall wood. In the UK, that can mean radical cutting to get rid of invasive non-native plants. I’ve seen what rhododendron does when left unchecked. All you get is rhododendrons and all other native flora and fauna disappears. Pine plantations tend to be nearly as sterile. A wood is not just a bunch of very tall plants, it is an entire eco system.
Small scale wood cutting undertaken by people who keep working responsibly with the same wood over many years gets beautiful results. People who know the wood, and care about it, who take no more than the wood can afford to let them have. People who go in and drag wood out, or work with ponies rather than bringing in heavy machinery. People who leave their wood healthy and full of life. It can be done. I’ve seen it done in many places and read about it in even more.
If an environment has never been messed with by humans, then we should leave it alone and not exploit it. However, if an environment has been worked with by humans for thousands of years, it may have evolved around us. That’s true for many woods, for meadows and for the kind of moorland rich in orchids and wildflowers. It isn’t true for the moorlands where the heather is burned off for grouse, it isn’t true of agri-business and giant monocultures, it isn’t true of deforestation. But, working with wood need not mean deforestation.
We can be participants in the natural world. We can work with nature without exploiting it.
