How Broad‐Scale Studies of Patterns and Processes Can Serve to Guide Conservation Planning in Africa
2007
FJELDSÅ, JON
Analysis of large‐scale biodiversity patterns can uncover general relationships and problems that need to be taken into account when conservation strategies are developed. Nevertheless, these large‐scale patterns need to be supplemented with information from local studies that can identify specific problems and determine how the land can be divided between conservation and development interests. I analyzed biodiversity patterns at three different scales to show how various scales of research contributed to conservation planning. A gap analysis for all of sub‐Saharan Africa revealed that the network of wildlife reserves provides insufficient protection of narrowly endemic and threatened species, mainly because such species are aggregated in certain areas with dense human populations. A more fine‐grained analysis of the distribution of forest birds of eastern Africa generally confirmed the results obtained with coarse‐scale data and added precision by identifying forest tracts where conservation actions should be concentrated. Detailed local distribution data for one of the prioritized areas, the Uluguru Mountains in Tanzania, suggest that the actions to halt the loss of biodiversity should be concentrated in the submontane zone, immediately adjacent to densely populated areas. To achieve conservation on the ground, these general planning tools must be supplemented with other kinds of research concerning land‐use and local knowledge and with approaches that promote more sustainable development. Different types of institutions will be needed for these different tasks, but it is essential that researchers maintain a dialogue with planners in this area.
