Abstract

Natural resource management has aroused recent interest in French Gujana, with investigations initiated in various parts of the country. Impacts of habitat disturbance, mainly from hunting and timber harvest on large mammal and bird communities, are a dominant topic. Line-transects are the common field method for estimating species abundance, but sampling methods need to be standardized. There are many publications on the topic, but often with emphasis on developing theoretical considerations, and can be far from expected field results. In this paper I present a concise and pragmatic view of line-transect methods, followed by a sampling application to a rainforest area prior to timber harvesting. About 300 km of line-transects were conducted in 1998 to assess large mammal species abundances before the harvest stage. Primates were used as a case study to illustrate how the different calculation procedures from line-transect baseline data may affect the calculated densities. The study area is traditionally hunted; the hunting impact isevident on a large set of species, mainly large primates and peccaries, preferred game species of local hunters.
