The service

Natural tree hollows can take decades to form, yet they provide important shelter and nesting opportunities for native wildlife. Where appropriate, we create habitat in two ways: by enhancing suitable existing features within standing trees, or by carving purpose-built hollows from larger salvaged timber and securely installing them back into the canopy.

Two ways of creating useful habitat.

Method one: enhance suitable existing features or cavities in standing trees where a useful hollow can be created or improved. Method two: create a purpose-built hollow from suitable larger salvaged timber and securely install it back into a tree for native wildlife.

Is my tree suitable?

Every hollow depends on the tree and the site.

Our goal is to retain and create useful habitat wherever the tree and site allow it. The first step is a look at the tree — request a quote and we'll take it from there.
