    A population model for the spot-tailed quoll
    Aarons, Jeremy ( 2007)
    This project describes the construction of a population model for the spot-tailed quoll (Dasyurus maculatus). The modelling uses the stochastic population modelling software ESSE1VTL4L (Endangered Species Survival and Extinction Analysis) (Todd et al., 2001). The model takes an age classified approach (Caswell, 2001), modelling yearly age classes, and is based on available data on survival, fecundity, and dispersal, and incorporating the effect of density dependence. The model is based on all available demographic data for this species. Much of the data is specific to the Badja and Tallaganda State Forest regions of southern NSW (eg. Belcher, 2003), and the model is designed to apply specifically to quoll populations located in this area. Some of the most detailed data available concerns the Northern Spot-tailed quoll D. m. gracilis (Burnett, 2000), which is closely related to D. m. maculatus and exhibits similar ecological traits to the southern quolls, but is significantly smaller and has a shorter life span.
