Author(s): Christoffersen B

Dataset Information

Site ID: XX-PTr

Site Name: Pantropical site

Variables: Sapwood Area

Date Range: Jan. 1, 1977 - Jan. 30, 2015

Description: This data package containsata synthesis of pantropical sapwood area as a function of tree size (height or DBH) for trees ranging in sizes 1 - 140 cm DBH and 6 - 44 m tall. Data span both natural tropical forests and plantations and rainfall gradients from deciduous dry tropical forests to everwet tropical forests, and come from the following countries: Queensland, Australia; Costa Rica; Panama; Sulawesi, Indonesia; Venezuela; Ecuador; Brazil; French Guiana; Bolivia. Three CSV files are included: SA_headers.csv: description of variables in the two files below SA.csv: tree size (DBH or height) sapwood area SA_references.csv: citation, bibliographic reference, and DOI for the published references from which data were extracted

QA/QC: None

Methods Description: For methods information please see the referenced publication.
