GPS inventory of timber trees from which local communities gather food resources in Cameroon, Gabon and the DRC.

This dataset contains the geograpahical coordinates of multiple-use tree species ('spp_lat' and 'spp_long'), which are used by local populations for the collection of food resources, while also commercially felled for timber in Cameroon, Gabon and the DRC ('ctry'). It focusses on Baillonella toxisperma, Entandrophragma cylindricum, Erythrophleum suaveolens, Dacryodes Buettnerii and Gambeya spp('spp'), around 10 villages ('vil', 'vil_lat' and 'vil_long') adjacent to five logging concessions in the three countries. In addition to coordinates there are columns indicating the diameter at breast height ('dbh' - cm), the altitutde ('alt' - m); the gender of the collectors who commonly visit the tree ('ntfp_col', where 'm', 'w' and 'c' indicate men, wo men and children); an indicator of how the production of the food resource at the tree has changed over the last 5 years ('prod_ind'); whether trips to collect resources from the tree are organised or not ('trips' ); other activities in the area around the tree ('agri', 'hunt', 'fish', 'ntfp' and 'other'); and whether the tree is within an adjacent logging concession or allocated agricultural zone ('overlap' and 'agrizone'). 5 male and 5 female informants were selected in each village. They led the researchers (1 male and 1 female) to the trees from which they commonly collected food resources. At each tree the geographical position was taken with a GPS, the dbh was measured and a series of questions concerning the collection, availability and accessibility of food resources from the tree. The points were mapped with polygons indicating logging concessions, indicating the type of land in which they were located (i.e. logging concession, community forest, unclassified forest estate, etc.)本数据集包含多用途树种的地理坐标（'spp_lat'与'spp_long'），这些树种既可被当地居民采集作为食物资源，也可在喀麦隆、加蓬及刚果民主共和国（DRC）被商业采伐以获取木材（'ctry'）。 本数据集聚焦上述三国境内毗邻5个采伐特许权区域的约10个村庄（'vil'、'vil_lat'及'vil_long'）周边的5个树种：*Baillonella toxisperma*、*Entandrophragma cylindricum*、*Erythrophleum suaveolens*、*Dacryodes buettnerii*及*Gambeya* spp.（'spp'）。 除地理坐标外，数据集还包含以下字段：胸径（'dbh'，单位：厘米）、海拔高度（'alt'，单位：米）；常采集该树种非木材林产品资源者的性别（'ntfp_col'，其中'm'、'w'、'c'分别代表男性、女性及儿童）；过去5年该树所产食物资源的产量变化指标（'prod_ind'）；采集该树资源的出行是否为组织化行为（'trips'）；该树周边区域的其他人类活动相关字段（'agri'、'hunt'、'fish'、'ntfp'及'other'，分别对应农业、狩猎、捕鱼、非木材林产品采集及其他活动）；以及该树是否毗邻采伐特许权区域或位于划定的农业区内（'overlap'与'agrizone'）。 每个村庄选取5名男性及5名女性信息提供人，他们带领研究人员（1男1女）前往其日常采集食物资源的树木点位。 在每棵目标树木处，研究人员使用GPS记录其地理坐标，测量胸径，并就该树所产食物资源的采集情况、可得性及可及性开展一系列问卷调查。 研究人员通过多边形图层对上述点位进行空间制图，以标注其所属的采伐特许权区域及土地类型（如采伐特许权区、社区森林、未分类森林地产等）。
