LBA-ECO LC-02 Biophysical Measurements of Forests, Acre, Brazil: 1999-2002

This data set provides diameter at breast height (DBH) measurements for 1,063 trees located at the Catuaba Experimental Farm, and 812 trees located in the Humaita Forest Reserve. Both sites are in the state of Acre, southwest Amazonia, Brazil. Measurements were made on individuals with DBH between 10 and 35 cm and individuals with DBH > 35 cm.

The Catuaba Experimental Farm is part of a forest fragment of approximately 800 ha. The Humaita Forest Reserve is located in a 1,500-ha forest band with dominant bamboo characteristic. Ten-ha areas were inventoried at both sites.

There is one data file in comma-delimited (.csv) format with this data set. There is also one companion data file with supplemental Catuaba site tree height and biomass data.

本数据集提供了位于巴西西南亚马逊地区阿克里州Catuaba实验农场和Humaita森林保护区共计1,063棵和812棵树木的胸径（DBH）测量数据。两地的测量对象胸径范围介于10至35厘米之间，以及胸径大于35厘米的个体。Catuaba实验农场隶属于约800公顷的森林片段，而Humaita森林保护区则位于一个1,500公顷的森林带中，该区域以竹林为主要特征。两处地点均对10公顷的区域进行了清查。数据集包含一个以逗号分隔的(.csv)格式的数据文件，以及一个补充Catuaba地点树木高度和生物量数据的伴随数据文件。
