What problems does the Hollowhog solve?

The loss of tree hollows throughout the landscape is well documented both here in Australia and in many other parts of the world. Hollows provide homes for at least 300 types of Australian animals including a reported 17% of bird species, 42% of mammals and 28% of reptiles. Worldwide more than 1000 species are known to depend on hollows for nesting and roosting.

Entrance Size

Many fauna prefer to squeeze through the smallest entry possible

Thermal Properties

Tree hollows have been demonstrated to remain cooler on hot days and warmer on cool ones than thin-walled nest boxes. For some fauna this attribute is critical for their ability to survive in harsh conditions.

Cavity Size

The internal cavity of a hollow needs to be large enough to accommodate either a single animal or multiple adults and their growing offspring.

Some of Our Work

There are many variations to the size and shapes of hollows that can be achieved using the Hollowhog. The tool is just as efficient at making salvaged log hollows and habitat for ground dwelling fauna.
