Estimate of Canopy Coverage and Density Plant Rahzya Stricta Decne Community Using Line Intercept Method in Kingdom of Saudi Arabia

Auther : Dr. Abdullah Bin A. AL-Saleh

     Desert areas are characterized by vegetation cover that consists of plant communities scattered and spread over large areas. This situation makes studying these communities are somewhat very difficult. However, there exist a number of methods that have been used for sampling, measuring and analyzing vegetation cover .The related literature reveals that such methods are wildly used in studying vegetation in western countries, with very few empirical studies that apply these methods in dry desert. It is the shortage of such studies in the Arab world in particular, and the importance of applied studies in the field plant in general that has brought up this study. The primary objective of the study is to estimate the property of Canopy Cover and Density of Rhazya stricta plant community in the Rawdhat AL-Masoudi At a distance135 Km Northeast of the city of Riyadh. To achieve its objectives, the study used the line object method (Line intercept method). This method has been explained in detailed both in theoretical and technical terms. This study showed an increase in coverage and intensity of Rhazya stricta plant and a lack of associated vegetation which can be attributed to overgrazing. Finally, it can be said that what happened to Rhazya stricta plant can be used as an indicator of environmental degradation. It should be emphasized that this plant has many environmental, therapeutic and economic benefits that should be utilized as much as possible by interest groups.
