Unfortunately most distributional data are only provided as presence-absence records at regional or national scales and cannot be used for making local conservation decisions. To date, two methods have been proposed for estimating local abundances and area of occupancy from coarse-scale presence-absence data. Kunin (1998) proposed the use of the fractal method, which assumes that species dis…
