Abstract


Knowledge on stem quality and assortment structure in forest is highly important for policy makers and the timber industry for different time periods. Sal (Shorea robusta) is important species in lowland of Nepal due to its incredible use and species richness. Present study was carried out in two community forest in Makawanpur district to find out the forest quality for timber production by analyzing forest condition and other quality indicators. Forest Inventory was conducted with 0.5% sampling intensity with systematic random sampling design following the community forest inventory guideline approved by the government of Nepal. The site variable measured (pH, Organic Matter, NPK content and soil texture) explained the soil condition of forest. Both community forest were of good in quality with timber volume of 86m3/ha and 151m3/ha in Chuchekhola CF and Neureni-Chisapani CF respectively. The ranking of preferred species for timber purpose was done to prioritize the species by users and hypothesis testing was done by using Friedman two-way ANOVA test to test the validity of this ranking. Shorea robusta followed by Terminalia tomentosa was found to be most preferred timber species. The most disturbing factor was forest fire followed by tree cutting and plant disease as the least disturbing factor identified by using Likert scale and Weighted Index Value Awareness on forest pest, disease and proper fire management plan have been recommended for the effective management of both Community Forest in sustainable basis.
