Summary

Many of the impediments to successful conservation management faced in countries such as Sri Lanka stem from a fundamental lack of data and analysis skills for interpreting biodiversity trends in relation to land use, management practices, and ecological or environmental factors such as invasive species and changing climates. Alternative metrics that can be useful in many situations where abundance is an infeasible metric include proportion of area occupied (PAO) and species richness (SR). PAO and SR are not new ideas, but methods that account for imperfect detection are, relatively, more recent. This chapter briefly outlines recently developed ’occupancy models’ that could be used in either situation. It illustrates some of the key ideas for application of PAO by considering a conservation issue from Sri Lanka, that of the red slender loris (Loris tardigradus).
