Step from the heat of the day into the forgiving shade of trees, and you’ll appreciate just what a blessing trees are. There’s more going on in tree shade than in other such cool spaces. On days of sticky humidity, the shade of trees is refreshing. When everywhere else is parched and dry, it often remains softer and damper beneath the trees.
Trees in our urban environments help bring the temperature down. This can be a life saver – high temperatures kill. It also brings down the cost and the amount of energy required to keep a space at a temperature humans prefer. Tree cover reduces our cancer risk as well.
In urban parks on hot days, it’s the tree shade that attracts people.
Without trees you don’t get much of a dawn chorus. You don’t get moths or bats, both of whom need trees to shelter in. Urban trees can support a surprising amount of wildlife. Where there are urban trees, there can be large flocks of sparrows for example – one of the many species we’ve pushed towards the edge.
While the utility of trees is something we need to take seriously, there is far more to a tree than its usefulness. Most will live far longer than an individual human. They are powerful, transformative influences in any landscape and simply, they have the right to exist. They do so much for us, and yet we measure them in terms of any mild inconvenience they may cause.
