There is a growing concern for sustainable forest management globally, and individual countries have been developing national policies and plans for forest management. This is the case in Nepal, but a large area of national forests is still under protection due to lack of people-centric management guidelines. In this study, diameter (DBH) and height were measured for trees, and frequency was recorded for regenerations (sapling and seedling), in concentric circular plots of 8.92 m, 5.64 m and 1 m radius respectively, in 89 plots from two community forests in the Mid-hills of Western Nepal to analyze whether the forests could be used sustainably. Regression analysis and the Mann–Kendall and Sen’s slope coefficient tests were performed to determine the composition and structure of forests in relationship with elevation which largely determines forests' type. It was found that seedling density decreases with increasing elevation, but sapling and tree density do not follow any significant pattern for elevation. The DBH size found to be inversely related to stand density for the two dominant tree species (Shorea robusta and Schima wallichii). In contrast, DBH did not vary significantly with elevation for Pinus roxburghii and Castanopsis indica. The DBH distribution of all trees (26 species) was found to decline consistently with stand age, indicating that the forests are in good condition to manage sustainably by a simple, people-centric and cost-effective regime of thinning and size-based harvesting. Results suggest that forest managers, forest users and policy-makers need to develop and implement user-friendly forest management directives.

全球对可持续森林管理的关注日益增加，个别国家一直在制定森林管理的国家政策和计划。尼泊尔就是这种情况，但是由于缺乏以人为本的管理准则，大片国家森林仍然受到保护。在这项研究中，在两个社区森林的89个样地中，分别测量了8.92 m，5.64 m和1 m半径的同心圆样地中树木的直径（DBH）和高度，并记录了再生频率（幼树和幼苗）。在尼泊尔西部中部山区分析森林是否可以可持续利用。进行了回归分析以及Mann-Kendall和Sen的坡度系数测试，以确定森林的组成和结构与海拔的关系，而海拔高度在很大程度上决定了森林的类型。已经发现，幼苗密度随着海拔的升高而降低，但是幼树和树木的密度并没有遵循任何明显的升高模式。发现DBH大小与两种优势树种的林分密度成反比（浓脂树（Shorearobista）和木荷（schima wallichii）。相反，松树和burg栗的DBH随海拔的升高没有显着变化。发现所有树木（26种）的DBH分布随着林分年龄的增长而持续下降，这表明通过采用简单，以人为中心且具有成本效益的稀疏和基于大小的采伐制度，森林处于良好的状况，可以可持续地进行管理。结果表明，森林经理，森林使用者和政策制定者需要制定和实施对用户友好的森林管理指令。
