Sanitary silvicultural operation in Wild Almond forest (Amygdalusscopariaspach.) (Case study: Khalilabad KhorasanRazavi, Iran)

ABSTRACT:Silviculture is the art and science of controlling the establishment, growth, composition, health and quality of forests and woodlands to meet the diverse needs and values of landowners and society on a sustainable basis. The goal of thinning is to control the amount and distribution of available growing space. By altering stand density, foresters can influence the growth, quality, and health of residual trees. Method of inventory was applied by randomized- systematic plot. Average number of trees in each base hectare (polygon of 22 hectares) is 20.9 and stem per hectares for regeneration was 13.9. The average percentage of forest cover in Amygdalus Khalilabad was 2.3 percent. In plan of Wild Amygdalus reserve we planted several time pots of seedlings but these were unsuccessful. Reforestation in this region because of climate change, rabbit and drought had not good results, then reconstruction and rehabilitation exist trees had more importance. This operation was accomplished for first time in KhalilabdTwonship in KhorasanRazavi province of Iran. Trees after sanitary cutting and pruning with basin system for water harvesting cause to promote quality of tree viability. We could conservation of old forest by silvicultural emprises.
