	Concerning this big SBEI (West of Morocco), its bioecological qualities especially its very specific and original flora has attracted naturalists for a long time. This region seems to be relatively preserved still despite the erosion and anthropogenic advanced threats. The most effective method to evaluate the degree of environmental¡¯s change caused by anthropogenic activity and climatic conditions is the multi-date study of land cover. For this, the purpose of this work is to analyze the land cover¡¯s changes evolution in this SBEI from remote sensing technics. Concerning that, we did a triachronical approach on data from 1988 to 2000 and from 2000 to 2010 (LANDSAT imagery). The land cover¡¯s maps that we got were produced from a supervised classification. The analysis of time series of LANDSAT images has shown that, during the period 1988-2000, the forests area decreased to the benefit of cultural practices (period before the creation of the SBEI), while the shrub strata distribution area has clearly increased during the period 2000-2010.
