For this study, ] 0 sample plots (3600m2) estabilished and in this sample plots quality and quantity and 765 tillergroup was investigated. investigation indicated that structure of even-aged coppice of Querclic Libani. Quantity characteristic such as average double diameter at breast height (d.b.h), number oftiller in bectar, number of till group, canoppy cover in hectar, average canopy diameter, average hight, perevailing hight and average persont of canopy caver was, ] 1.8 em, 3133.9, 212.5, 4251.3m2, 4.36m, 3.61m, 4.6Im, 42.5%, respiqtively. Quantity of study mass indie'ated that do not any foult in stand, ston in this area composid of carstic lime and volcanic ston. This lime have a seam system and storage water in it.s, therfor case the solation of the limes and remine clays from the destruction of lime-cly soils. Soils of study area composid of antisojls that developed from the profils. Thus lessive prosses was cases appear caIssie horizon and development of this profile. By this reason in any divission ensiptisoils order was observed. Jeneraly becoming hevey tentur and incrised persent of T.N.N and PH of this area was weal! to average alkali and clos'nt salin restriction. For study of botany in these estabilished sample plots, investigation show that study area composid of 16 famili, S8 genus and 74 spesies.
