Trees in our environment improve mental health. Walking, and being amongst trees can also help with mental health. Trees are good for us. They don’t solve everything – if your brain chemistry needs changing, a tree won’t do that for you. If the rest of your environment is hostile, stressful and making you sick, then the reprieve of tree time won’t fix that. However, we do all benefit from access to trees.
Trees are good company. They don’t judge, criticise or demand. They’re usually full of birds and other wildlife. They give us soft, generous light, protected for the greater part from sunstroke, heatstroke, and sunburn. In autumn they bless us with colour. They are beautiful as they age, beautiful when diseased, when gnarly, or twisted, or stark in winter. They help us challenge our limited ideas about acceptable physical shapes.
One of the big problems with mental health care at the moment is the emphasis on individual responsibility for good mental health. Let’s look at the tree issue again. Access to trees is not purely an individual issue. If your council cuts down all your street trees, the loss is yours, but the choice wasn’t. Planning decisions that destroy green spaces are often beyond our control, however much we might protest. Industrial landscapes where there are no trees probably aren’t your choice either, but you may have to work there. Affordable public transport to access green spaces isn’t something you get much say in. Accessible treed spaces for people who are less mobile are also not individual choices.
Our mental health is profoundly affected by the physical environments we inhabit. The role of green space in alleviating stress and promoting good mental health isn’t factored in anything like enough. Being in poverty increases the chances that you’ll have trouble accessing green space because you just won’t be able to afford to get there. It’s no good telling people to walk under trees to help with their mental health if they don’t have any trees they can get to. It’s no good assuming that everyone has a car and can afford to drive it to their nearest wood.
Our systems aren’t run to maintain good mental health in the populous, and what happens around trees is an example of this. We tell people to spend time with trees, but governments don’t enable that in any way. Trees should be readily available to all people, you should not need to make an effort to seek them out.
