Last Thursday we were back at High Chart, carrying out some birch thinning and finishing off a round of “tree popping”on the heathland opposite the Carpenter’s Arms.

You might be wondering: what on earth is tree popping?

It’s the removal of unwanted saplings that “pop up” all over the place. If left, these young trees quickly take hold and can be much harder to manage once they’re established. To tackle them, we use a handy tool called a tree popper—a bit like an oversized pair of pliers with a long lever arm. The jaws grip the stem, and with a push and pull of the handle, the entire sapling—roots and all—is lifted clean out of the ground. It’s an efficient way to do the job, without all the heavy digging and straining.

Why focus on birch?

Silver birch is a pioneer species: fast-growing, quick to colonise, and highly competitive. Left unchecked, it can outpace slower-growing trees like oak, reducing their growth and quality. By thinning birch, we help ensure oak and other species have the light, space, and nutrients they need to thrive.

On heathland, birch poses another challenge. Heaths can turn into woodland surprisingly fast if birch saplings are allowed to spread. Removing them helps preserve this rare and valuable habitat.

Get involved!
