Site description and location of direct measured trees in the Ankeniheny Zahamena forest corridor, Madagascar
Data were collected as part of a project funded by the Ecosystem Services for Poverty Alleviation (ESPA) programme under work package 4, P4GES project, grant references: NE/K008692/1, NE/K010115/1, and NE/K010220/1.

Provenance & quality
The selection of sites was based on the AGB values per site in relation to the representativeness of each tree size (proportion of trees per DBH class). In order to establish this relation, AGB per site was divided at three class so that each class has the same number of values (a percentage at around 33% of the total number of sites for each class). The aim is to see for each site, which category of tree (in terms of DBH) contributes the most to its biomass (ABG). Afterwards, consideration of contribution of each tree size into AGB density in Mg.ha-1 per site for each ZOI, at least 3 sites for each ZOI were selected for BGB direct measurements. The choice of sites also takes account of the accessibility, any restriction in field process in relation with this protected area zonage.
Target trees were chosen from the four dominant species sorted out from the forest inventory. Target trees were selected by considering the selection of zone, sites, diameter classes and species. Three categories of trees were considered, trees with DBH≥ 20cm, trees with 10≤DBH<20cm and trees with 5≤DBH<10cm.
Following all these process, in total, 54 target trees were selected for direct measurements of BGB: 2 zones * 3 sites/zone * 3 species per site * 3 diameter class / species.
