Tec-Door Wildlife Hollow
(chainsaw hollow)

Treetec designed Tec-Door with Tec-Spout. Arborists use chainsaws to create a narrow introduced wildlife hollow with Tec-Door entry plate on rough barked tree.

Our Treetec team have developed the Tec-Door introduced wildlife hollow methodology over some years of experimentation.  It provides a range of advantages and eliminates a few problems but it’s still a work in progress.  The narrow width reduces wound impact whilst allowing generous internal dimensions, the Tec-Doors reduce issues related to ventilation, drainage and longevity.

A narrow slot is cut into the tree, the wider internal cavity is then created with a chainsaw or other tools and then a pre-made Tec-Door is fitted.  This methodology allows enough access for internal excavation but keeps the wound narrow which is a key issue for protecting tree structural integrity. We’ve installed thousands of these cavities.

In partnership with ARI (DELWP) as part of a research project we’ve installed over 100 Tec-Door wildlife hollows into fast growing Mountain Ash of the Central Highlands Victoria, these hollows were designed to suit Leadbeater’s Possums.  The research on occupancy, cavity microclimate and tree response is ongoing.
