Abstract :

Understanding the vegetation cover of the each region is foundation of ecological studies and environmental planning. This study aimed to identify the type of tree and shrubs were conducted in the region of Big Pooled in North Kherson. In this regard first, forest region map and shrub lands area were prepared using the visual interpretation with IRS-P6 satellite images and vector layers on base google earth. The tree or shrub layer cover components were separated by density classes. Therefore for identified to each Polygon using the dominant type at least half a hectare by referring to area and field visit. To improve the accuracy of perceptions about the area of each Polygon, on vector map of the areas covered by trees and shrubs were designed a systematic random sample include of 65 transect. The information that was collected includes the type and ground operations cover for each species on the samples and for the assessment final correct data type named, using this information. In this study, 25 species of trees and shrubs were identified in 35 types. The type identified species means species that have appeared as the first or second species, was formed including 11 types of Jonpierus, 7 type of Acer, 9 type of Paliurus Spina-christi and Berberis with 2 types. The highest density class was in juniper type and juniper with associated species was in the 50-75% class.
