Tree hollows form critical habitat for fauna (Gibbons & Lindenmayer, 2002; Newton, 1994). Many species rely on hollows for purposes such as shelter and breeding, and if there are not enough of these resources in the landscape, this negatively affects the ability of populations to persist in an area (Gibbons & Lindenmayer, 2002; Newton, 1994; Smith & Lindenmayer, 1988; Woinarski et al., 2011). In addition, species may prefer to only use hollows of certain sizes (Goldingay, 2009, 2011). It is therefore essential to be able to accurately quantify the number and size of hollows across the landscape: accurately quantifying hollow density will improve habitat suitability assessments and thus better inform management and conservation efforts.
