Ecosystem Evolution Scenarios in the Ferlo Biosphere Reserve Based on the Iucn Red List of Ecosystems Criteria
Author(s): Diara Sylla*, Aissatou Sene and Aliou Guissé
This study assesses the applicability of the International Union for Conservation of Nature (IUCN) Red List of Ecosystems criteria in a typically Sahelian environment, namely the Ferlo Biosphere Reserve in Senegal. The methodology is based on the evaluation of different ecosystem types using five assessment criteria: two criteria related to spatial distribution (qualitative factors), two criteria addressing ecosystem functioning through biotic and abiotic interactions (quantitative factors), and a final criterion based on quantitative risk analysis. Ecosystems are subsequently classified into one of eight threat categories—Collapsed, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient, and Not Evaluated—according to the thresholds defined by the IUCN framework. The analysis relies on land-use and land-cover maps.. Read More»
