Abstract

Identifying REGENERATION characteristics is a decisive prerequisite in forest stands management. Therefore, the objective of this research was to 1) present the most appropriate tree species for reforestation within stand GAPs and 2) study the effect of RELATIVE LIGHT INTENSITY on REGENERATION characteristics. Quantitative characteristics were measured in 10 GAPs at district one of LOVEH forest in Golestan province. Results showed differing frequencies of species depending on GAP positions and relative light intensities. Except checker (Sorbus torminalis (L.) Crantz) REGENERATIONs, no significant difference was observed between mean of spring shoot length within GAP positions. Annual height GROWTH of checker was maximum for 40% RELATIVE LIGHT INTENSITY, while the annual diameter GROWTH of hornbeam (Carpinus betulus L.) and wild cherry (Prunus aviumL.) were maximum for RELATIVE LIGHT INTENSITY ranging between 30 and 40%, respectively. No significant difference for relative light intensities was observed between other spices characteristics. Therefore, the study concludes that the highest attention should be paid to species mixtures and their ecological requirements for reforestation within the GAPs.
