Résumé
This thesis adopts landscape ecology as the conceptual basis for describing the interpreting the relationship between pattern and process in the Souss-Massa National Park (SMNP) southern Morocco. Specifically the main aim of the thesis was to produce a hierarchical landscape ecology classification and map of the SMNP, that could be effectively used in predictive modelling of feeding habitat suitability for the critically endangered northern bald ibis (Geronticus eremita L.). A spatially referenced GIS database was constructed by the classification and mapping of specific landscape attributes. A land cover classification was produced using NDVI and MSAVI multi-temporal SPOT HRV satellite image composites. Following hierarchical data integration a four level landscape classification was produced with associated maps. In order to extend the database for bald ibis modelling, a knowledge-based approach to predictive vegetation mapping was adopted, based on vegetation communities identified by TWINSPAN classification of field vegetation data, the spatial landscape ecology output and other layers in the database. A predictive model of bald ibis feeding habitat suitability was developed using logistic regression modelling, a probability surface was interpolated from the results using kriging and a feeding habitat suitability map was produced. The landscape ecology map was an effective predictor of bald ibis feeding habitat suitability in multivariate models, the results of modelling demonstrating that feeding habitat can be accurately predicted and mapped at the landscape scale. ?? The results of habitat suitability modelling and mapping have clarified bald ibis feeding habitat requirements in the SMNP both in terms of quality and distribution, and shows that only 16.6% of potentially suitable habitat can be regarded as optimal.
