Amphibienforschung am Monts Nimba, Guinea, Westafrika

Amphibian monitoring data on Mount Nimba will fulfil the following goals:

1. assess distribution and monitoring populations of particular species of outstanding conservation interest (i.e. Nimba Toad and other species of conservation concern),

2. establish sound baseline data for particular species / species assemblages against which future data can be compared (if possible these data should allow for a comparison with historic data sets as well),

3. identify, characterize and evaluate especially sensitive and threatened areas on Mount Nimba (i.e. foreseen mining enclave, adjacent World Heritage Site),

4. monitor amphibians as surrogate species for other organisms (i.e. stream species, primary forest specialists),

5. in the future data from points 1-4 should allow for a separation of different effects on the amphibian and especially the Nimba Toad populations (e.g. mining, fire, agricultural encroachment, grazing, global warming including a possibly altered precipitation regime),

6. establish national capacity (researchers and para-ecologists - field assistants) to undertake most of the field work and data analysis, at least over the medium-term. During the near-term perspective, foreign capacity on data collection, evaluation and analysis is irreplaceable.

In 2007 we examined the distribution of the Nimba Toad and recorded forest amphibian assemblages. Thorough plot searches were carried out systematically over the whole mountain ridge and scattered within the forests around Mount Nimba. These data allowed for preliminary detailed understanding of the distribution and habitat needs of the Nimba toads, as well as a coarse overview of the distribution and assemblage of amphibians in the World Heritage Site and the mining enclave.

The goals for the 2008 field and laboratory campaigns are:

1. to close potential knowledge gaps on the distribution of the viviparous Nimba Toad,

2. to continue population monitoring of the Nimba Toad at selected places,

3. to establish a habitat model for the Nimba Toad that will be tested in the field,

4. to start investigating population genetics of the Nimba Toads in order to evaluate the connectivity and the viability of current populations,

5. to continue monitoring target species of conservation concern within stream habitats.
