This study examines the analysis of natural vegetation cover, the spatial distribution and identification of the most important existing plants and trees species in Ajloun Governorate by choosing spatial samples on Quadrat way which based on the frequency account of grass plants and apply it in (the Runkaier Method). In addition, it will analyse numbers, frequency, abundance, density, the relative importance to trees and the coverage which applied according to (Blankuet way). This study is based on the field survey Spring Season in 2018. It concludes that there is 137 species of herbaceous plants; the most frequent between them were the Stipa capensis, Cynodon dactylon and aventa sterilis. Also, it concludes 23 species of trees and shrubs which numbered 938 individuals; The most frequent among them were Quercus calliprinus oak, Crataegus azarolus and Quercus aigilops, covering an area 4455M2 which is 55.7% percent of areas of samples which are covered by Quercus calliprinus ,Quercus aigilops and Pinus halepensis. The Quercus calliprinus was the most dominant type between all calculated variables. Subsequently, The study is classified spatial samples by number of species, coverage and type of cover in the form of illustrative maps.
