| Abstract | ||
| The study was which included choose and delineation representative locations for rangeland which was that difference vegetation cover and that to suffer from cause and degree difference degradation : Hatra, Tal abta, Baashiqa, Tal- Kaif, Shirqat and Tlool- Albaj. And additions soil sample representative locations for rangeland. The samples were brought to the lab, to make some of determination and measurements physical and chemical on the soil sample which involves texture, organic matter, CaCO3, CaSO4. 2H2O, Ec and pH. wholly depending more than satellite images which made indexes values accounts and plant indicator, and they are(NDVI, VI, TNDVI, SAVI, MSAVI, IPVI). Besides preparing satellite images NDVI and delineation degrees of degradation by using group of programs. Noticed through the results indexes values and plant indicators which consider on the plant cover in the locations which located to the north of Ninevah which represented with Baashiqa and TelKaif, where the NDVI value occurred (0.16, 0.29)respectively, and occurred indices SAVI,MSAVI and IPVI (0.44, 0.44,1.15) in Baashiqa location, and existed that low value in Hatra location of occurred (0.09, 0.11, 1.03) respectively. The results extracted that Al-Jazera areas suffer from risks of degradation and desertification largely. So that degrees of the sever degradation and very sever degradation were common. And addition soil properties degradation of physical and chemical caused be overgrazing, processes of plowing and mismanagement . | ||
