Description
Worldwide, tropical landscapes are increasingly dominated by human land use systems and natural forest cover is decreasing rapidly. We studied frugivorous butterflies and several vegetation parameters in 24 sampling stations distributed over near-primary forest (NF), secondary forest (SF), agroforestry and annual culture sites in the Northeastern part of the Korup region, SW Cameroon. As in other studies, both butterfly species richness and abundance were significantly affected by habitat modification. Butterfly richness and abundance were highest in SF and agroforestry sites and significantly lower in NF and annual crop sites. Butterfly species richness increased significantly with increasing tree density, but seemed to decrease with increasing herb diversity and density in annual crop farms. A significant negative correlation was found between butterfly geographic range and their preference for NF sites. Our results also showed that agroforestry systems, containing remnants of natural forest, can help to sustain high site richness, but appear to have low complementarity through loss of endemic species confined to more undisturbed habitats. Our study also indicated that the abundance of selected restricted-range butterflies, particularly in the family Nymphalidae, appears to be a good indicator to assess and monitor forest disturbance. © Springer 2006.
