In 1979 there was only one national park in the forested Amazon region of Brazil. In that year Brazil adopted a conservation plan for the Amazonian region, proposed in 1976 as part of a system of conservation units for the whole country. Since then a further four national parks and a number of biological reserves and ecological stations have been established. The plan, which gives priority to ecosystem protection, takes the geographic diversity of plant species into consideration but not that of the fauna. The authors examine the effectiveness of the plan in protecting the primate families Callitrichidae, Callimiconidae and Cebidae and suggest how it could be adapted by recognising the importance of rivers, which limit the distributions of many primate species and subspecies as well as those of many other mammals, birds and plants.
