Résumé partiel
This study was conducted in Al Sabaloka Game reserve, as an established reserve in the dry land ecosystem. It aimed to evaluate the current climatic conditions and trend of change, to determine the current status of wildlife and their habitat in comparison with the previous time, to detect the effects of climate change on the habitat and to assess the wildlife problems in dry lands habitat. The methodology that was adopted in this study has two types of data, namely primary data and secondary data. The primary data involved climatic data for the study area during previous thirty years (1978- 2007), two Landsat satellite images for the years 1987 and 2000, ground assessment data and questionnaire. The sources of secondary data include relevant documents, records and annual reports. The data for the major climatic elements (rainfall, temperature, relative humidity and winds) for the study area were collected and grouped into three periods (1978 – 1987, 1988 – 1997and 1998 – 2007). The data were analyzed by using excel program. The assessment of habitats components (cover, food and water resources) were detected by using both remote sensing techniques and field check using GPS. The Landsat Satellite Images of 1987 and 2000 were analyzed by ERDAS software. Reconnaissance survey and field visits were made firstly then five sampling units (A, B, C, D and E) were selected systematically as the most representative sites of natural vegetation cover. The units were surveyed and checked on ground by GPS and then interpreted in the Satellite images. The ground survey information about the state of wildlife habitats in Al Sabaloka game reserve includes evaluation of trees composition, frequency and coverage, the occurrence and distribution of wild animals and surrounded hazards. The questionnaire was conducted for the local people to compare the past and present status of wildlife in the area and to evaluate the change in the climatic conditions.
