Carved hollows are proving an asset in conservation practice.
Spring is always an exciting time to be in the field, but 2025’s wildlife monitoring has been particularly rewarding. An impressive variety of native species have been observed using hollows Habitec created through arboricultural carving techniques. These observations reinforce what many in the industry already recognise: arborists have a powerful role to play in restoring lost habitat.
As nature intended
During recent monitoring, Habitec recorded a range of species including owls, sugar gliders, brushtail possums, microbats, galahs, cockatoos, eastern and pale-headed rosellas, kookaburras, wood ducks, and both scaly-breasted and rainbow lorikeets making use of carved hollows. Some hollows showed multiple occupants or sequential use by different species over time, an encouraging sign of how quickly these artificial refuges are being accepted.
For decades, the shortage of natural hollows has been one of the leading factors contributing to the decline of many hollow-dependent species. Traditional habitat restoration methods, such as nest boxes, remain valuable tools, but carved hollows offer a more natural, durable, and arborist-driven solution that integrates seamlessly into tree management and risk-reduction works.
Each carved hollow mimics the natural decay processes that can take centuries to occur in mature trees. When done correctly, the results are immediate, safe, and functional hollows that provide shelter and breeding opportunities without compromising tree structure or public safety.
By the book
The Habitec team has spent years refining the methods and tools behind successful hollow creation, from site selection and species-specific design, through to chainsaw technique and post-installation monitoring. Those lessons have been compiled into the new publication Carved Hollow Creation, a practical guide written for arborists, land managers, and conservation professionals.
This season’s results are a strong reminder that carved hollows are more than just an ecological experiment.
They’re a proven, scalable technique that allows the arboriculture industry to actively rebuild habitat where it’s needed most. Every carved hollow represents a small act of restoration, and together they’re making a measurable difference for wildlife that depends on arborists to think beyond removals and into long-term habitat creation.
