Abstract : Wadi Yalamlam is known as one of the significant Wadies in the west of Saudi Arabia. It is a very important water source for the western region of the country. Thus, it supplies the holy places in Makkah and the surrounding areas with drinking water. Floristic composition of Wadi Yalamlam has not been comprehensively studied. For that reason, this work aimed to assess the Wadi vegetation cover, life-form, chorotype, diversity, and community structure. The Wadi was divided into seven stands. Species richness and dominance were calculated using both Shannon-Wiener and Simpson's indices. Geographic Information System (GIS) was used to obtain density mapping. On conclusion Stands 7, 1 and 3 were the richest with the highest Shannon index 2.98, 2.69 and 2.64 respectively. On the other hand, stand 6 has the least plant biodiversity with Shannon index of 1.8. The study also revealed the presence of 48 different plant species belonging to 24 families. Fabaceae (17%) and Poaceae (13%) were the main families that form most of the vegetation in the study area, while many families were represented only by 2% of the vegetation of the Wadi. GIS resulted in advanced alternative methods for representing vegetation maps far from regular field surveys and photo analysis. Using predicting the distribution of vegetation across a landscape based on the relationship between the spatial distribution of vegetation and certain environmental variable.
