If you could only plant one tree in your lifetime, plant an oak. No other tree does more for the world around it - or sticks around long enough to prove it. Oaks have been growing in the Northern Hemisphere for millions of years, and there are around 500 species of them spread across Europe, Asia, and the Americas.
They come in all shapes and sizes — from the giant spreading English Oak to compact evergreen varieties you can grow in a smaller garden. What they all share is an almost stubborn desire to live for a very long time, and an incredible ability to support the wildlife around them. And it can get very old!!
Ecological Role
Here's a number that should stop you in your tracks: a single mature oak can support over 2,300 species of insects, birds, mammals, and fungi. No other native tree comes close. Jays, squirrels, badgers, bats, woodpeckers, rare beetles — they all depend on oaks at some point in their lives.
Even a dead oak keeps giving. Standing deadwood becomes a hotel for hole-nesting birds and specialist beetles. Fallen branches rot slowly and feed fungi, which feed more insects, which feed more birds. The furrowed bark alone is home to dozens of species of moss, lichen, and overwintering insects.
If you want to do something genuinely good for local wildlife, planting an oak is one of the best things you can do. It won't happen overnight — but oaks are patient, and so is nature.
