Alteration of plant diversity after fire in Zagros forest stands, case study: Marivan forests

Abstract

Natural plants are under risk of natural and human damages. Natural and human-made fires can change landscape and cause ecological disturbance, which can affect nature cycle of plant cover and ecological structure. The systematic random sampling method (50 x 50 m. network) was applied in two forest sites (each 15 hectares) at Marivan forests of Kurdistan province of Iran (burned and control) to layout 30 circular 2.5 acre and 30 four m-2 sampling plots on the burned and the control sites, for wooden and herbaceous plant species, respectively. Diversity, richness and evenness indices were calculated and compared, using the PAST software and Unpaired T- test method. The results showed that there was not significant difference between the two sites in respect to average sprout clumbs per plot. There were significant differences between the two sites (ρ
