Abstract:
We investigated the influence of forest fragment size and isolation on the bird assemblages in the species- and endemic-rich
sand forests of the Maputaland Centre of Endemism, southern Mozambique. Point-centre surveys were conducted across 12
sand forest patches that varied in size and isolation. Patch size and isolation had little influence on bird species richness, but
the number of individuals decreased significantly with increasing isolation. Furthermore, bird abundances were correlated to
a combination of the size and isolation of patches. Many forest specialists, in particular large-bodied frugivores, were highly
sensitive to reduced patch size and increased distances between patches. Further fragmentation of the landscape may
therefore impair the ability of these forests to support viable populations of forest specialists.
