Poisson generalised linear mixed models of the number of animals in each occupied hollow tree.

Candidate explanatory variables included the number of hollow trees per site, tree form and forest age class. Non-significant terms were dropped from the full models. For categorical variables (e.g. Tree form) the significance test results for the variable are presented on the line of the first category. For Leadbeater’s possum, we present a model that includes a marginally non-significant interaction between forest age and hollow tree count for comparison with models in tables 2 and 3. Likewise, hollow tree abundance and tree form explained no variation in the number of greater gliders per occupied tree: we present the model for comparison with the site abundance and tree occupancy models.*Or variance component estimate for random terms.
