Data for land use legacy effects on woody vegetation

Three zip-archived, comma delimited csv files with (1) DBH data, (2) species richness data, and (3) species composition data. For (1), columns include site ID, short name of tree species (composed of first three letters of genus name and first three letters of tree species name), tree DBH (in cm), land use history (i.e. permanent or converted farmland), and tree species type (i.e. forest specialist, generalist, or pioneer species). For (2), columns include kebele ID (GBD = Borcho Deka, GKH = Kela Harari, SDM = Difo Mani, SGB = Gido Bere, TBW = Bere Weranigo, and TKF = Kuda Kofi), site ID, land use type, total species richness, total species abundance, forest specialist species richness, forest specialist species abundance, pioneer species richness, pioneer species abundance, generalist species richness, generalist species abundance, proportion of vegetation cover within the site (in %), wetness index, historical (1973) distance (in m), current (2015) distance (in m), land use history (permanent or converted farmland), and altitude (in m above sea level). (3) is a site-by-species abundance matrix with site IDs and species represented by their short name (composed of first three letters of genus name and first three letters of species name).

本数据集包含3个经ZIP压缩的逗号分隔式CSV文件，分别涵盖(1)胸径（DBH, Diameter at Breast Height）数据、(2)物种丰富度数据以及(3)物种组成数据。
对于(1)胸径数据，其字段包括样地ID、树木物种简称（由属名前3个字母与树种名前3个字母组合而成）、树木胸径（单位：厘米）、土地利用历史（即永久农田或已改造为农田的地块）以及树木物种功能类群（即森林专性种、广适种或先锋种）。
对于(2)物种丰富度数据，其字段包括凯贝莱（kebele）ID（其中GBD对应博乔德卡(Borcho Deka)、GKH对应凯拉哈拉里(Kela Harari)、SDM对应迪福马尼(Difo Mani)、SGB对应吉多贝雷(Gido Bere)、TBW对应贝雷韦拉尼戈(Bere Weranigo)、TKF对应库达科菲(Kuda Kofi)）、样地ID、土地利用类型、总物种丰富度、总物种多度、森林专性种种丰富度、森林专性种种多度、先锋种种丰富度、先锋种种多度、广适种种丰富度、广适种种多度、样地内植被覆盖比例（单位：%）、湿度指数、1973年历史距离（单位：米）、2015年当前距离（单位：米）、土地利用历史（永久农田或已改造为农田的地块）以及海拔（单位：米，以海平面为基准面）。
(3)为样地-物种多度矩阵，包含样地ID以及以简称形式表示的物种，物种简称为属名前3个字母与物种名前3个字母的组合。
