  The research design of elimination trail has performed in the form of randomized completely blocks design with 3 replications and 8 treatments ( species of needleleaves) in Kohsarkande forests of Neka, Mazandaran(North of Iran). For investigation of the plant biodiversity the treatments of needleleaves in this elimination trail, the aforestation of hard woods(Maple) and the bare area were selected. For determination of characteristics of top soil(0-10cm), a total of 24 samples of treatments were taken(per treatment 3 samples) and topsoil chemical properties such as EC, pH, T.N.V, caso4, P, K and organic matter were analized. To determin of plant biodiversity in these treatments Simpson´s index, N2 Hill´s index, Mc Arthur´s index and Shannon-Wiener function were used and for determination of species richness of these treatments Margalef ´s index and Menhinick´s index were employed. The results of this research showed that the treatments of the bare area, Cryptomeria japonica and Pinus pinaster with minimal survival and at least litter covering percentage have the highest biodiversity of plant covering on the floor of these treatments. The treatments of Pinus teada and the aforestation of hard woods(Maple) with maximum survival and the highest litter covering percentage have the lowest biodiversity of the plant covering on the floor of these treatments.
