Metrics, diversity, and dynamics of fragmented landscapes with varying intensity of land use
Short description: Natural diversity and dynamics of forest-savanna mosaics and their anthropogenic alteration are studied in direct comparison of the protected areas Comoé National Park and Lamto Reserve with the utilised countryside neighbouring them. Recent and historic remote sensing data of various sources are employed in cooperation with W01 and W02 for carrying out the analyses, for completing the BIOTA-West GIS, providing a spatio-ecological reference for all projects working in these areas, and upscaling the results onto a subcontinental level in close cooperation with W11 and IMPETUS-A3.

Impact of land use and disturbance regime on forest fragmentation and biodiversity changes
Short description: Human impact on the forest-savanna mosaic due to recent and former land use and cultural practices is studied with botanical relevés and interviews among the inhabitants in the direct neighbourhood of protection areas in order to relate the results to the ones obtained in the protection areas by the other work packages. This is achieved in the weakly populated countryside south of the Comoé National Park and in the densely populated surroundings of the Lamto Reserve. Data assessment is designed to be combined with a proposed work package on the socio-eoconomical situation and development in both regions.
Workpackage WP04.3

Edge effects and dynamics of dry forest islands
Short description: The forest-savanna border is considered to be particularly sensitive to dynamic processes in the forest-savanna mosaic. Functional relationships are determined with various edaphical, microclimatic, and biotic parameters that are recorded along eight continuous forest-savanna transects in the Comoé National Park. Their gradients are identified to determine reach and dynamics of ecotones and, hence, the influence of edge effects. The data assessment meets the requirements for designing a forest-border model in a proposed cooperation with S09.

Vegetation monitoring and biodiversity observatories
Short description: Phytodiversity is monitored in the biodiversity observatories inside and outside the Comoé National Park and Lamto Reserve according to the methodical BIOTA standards in order to contribute to the corporate analysis of phytodiversity dynamics along the continental BIOTA transect by S06. Tree individuals larger than 1 cm dbh are marked and mapped in ranged plots to gain detailed knowledge on regeneration dynamics in the forest-savanna mosaic.

Soil properties along forest-savanna ecotones
Short description: The possible impact of soil properties on distribution and dynamics of forest islands in savanna was studied in cooperation with Prof. Jörg Grunert, Geographical Institute, University of Mainz. Along six transects in the Comoé National Park, soil-physical properties were examined, and 169 soil samples were taken for carrying out soil-physical analyses in the laboratory.
