Woodlands in the Sudanian zone are under different management regimes, including total protection and controlled use mainly for feeding livestock and collecting fuelwood. This study conducted in Sudanian woodlands of Benin, around the Biosphere Reserve of Pendjari (BRP) aimed to: (i) determine the effect of selective stem thinning and branch pruning on the production of standing biomass of the woodlands; and (ii) assess the effectiveness of Sudanian woodlands to meet the fuelwood demand of the local population. Three vegetation units of about 80 m × 80 m each were identified, relatively uniform floristically and structurally, and representing three woodland development stages in Sudanian woodlands. Three random blocks (replications) of 20 m × 20 m each were demarcated within each vegetation unit. Each block was then divided into four treatment plots of 10 m × 10 m each. Treatments were randomly allocated and consisted of i) no thinning (T1), ii) 30% thinning (T2), iii) 60% thinning (T3), and iv) 100% thinning (T4). Standard branch pruning was applied to all remaining stems. The species name, diameter and/or height of the remaining stems ≥ 1 m height were recorded twice during the year period between 2015 and 2016. A semi-structured questionnaire was randomly applied to 150 households to record detailed information on the tree species as well as the quantity of fuelwood used or sold each day. Thinning and pruning had a positive effect on biomass production. The best biomass production (0.88 t/ha/year or 15,028.5 t/year for an area of 16,938.7 ha) was obtained with 60% thinning and pruning. Whatever the treatment, the biomass production did not meet the demand for fuelwood of the local population around the BRP. A deficit between 69.5% (T1) and 64.6% (T3) was observed. The mean per capita fuelwood needs of the households was 1.3 kg/day, and decreased with increasing household size. Extending the experimentation over a longer period (at least ten years), and establishing and using the allometric equations of recorded tree species will improve the estimation of the biomass production of these woodlands.

苏丹地区的林地实行不同的管理制度，包括全面保护和控制使用，主要用于饲养牲畜和收集薪柴。这项研究是在Pendjari生物圈保护区（BRP）周围的贝宁苏丹林地进行的，目的是：（i）确定选择性茎细化和枝条修剪对林地固定生物量生产的影响；（ii）评估苏丹林地满足当地居民薪柴需求的有效性。确定了三个植被单元，每个单元约80 m×80 m，在植物学和结构上相对均匀，代表了苏丹林地的三个林地发展阶段。在每个植被单元内划出三个20 m×20 m的随机块（重复）。然后将每个块划分为四个每个10 m×10 m的处理区。处理是随机分配的，包括：i）不间断（T1），ii）30％间断（T2），iii）60％间断（T3）和iv）100％间断（T4）。将标准的树枝修剪应用于所有其余的茎。在2015年至2016年的一年中，两次记录了剩余名称≥1 m的茎的物种名称，直径和/或高度。两次随机抽取了半结构问卷，对150户家庭进行了记录，并记录了有关树种的详细信息。每天使用或出售的薪柴数量。间伐和修剪对生物量生产有积极影响。最佳的生物量生产（0.88吨/公顷/年或15,028.5吨/年，面积为16,938.7公顷），同时进行60％的稀疏和修剪。不管怎样 生物量生产不能满足BRP附近当地居民对薪柴的需求。观察到69.5％（T1）和64.6％（T3）之间的缺陷。家庭的平均人均薪柴需求为1.3千克/天，并随着家庭规模的增加而减少。将实验扩展到更长的时间（至少十年），并建立和使用记录的树种的异速方程，将改善对这些林地生物量生产的估计。
