Primate abundance and distribution: background concepts and methods
Primate abundance and distribution: background concepts and methods
Primate distribution, abundance, as well as their spatial and temporal population trends, are important data to collect in the aim of gaining knowledge on ecosystem functioning, but can also form the basis for management decisions and offer a means by which to evaluate the effectiveness of different conservation strategies. However, estimates of species distribution, population size, and trends may vary considerably in quality depending on the choice of survey design and the methods used. In this chapter, details are provided on the different steps involved in the planning of a primate survey, and three case studies are used to illustrate the variety of options available according to study species and survey objectives. When carefully designed, a primate survey can yield precise and accurate estimates of population distribution, abundance and trends, and thus provide an information source which supports researchers, wildlife managers and local government in decision-making processes.
