Fig. 1From: Recommendations for the use of tree models to estimate national forest biomass and assess their uncertaintyDistribution of volume and biomass equation’s sample size on GlobalAllomeTree. Sample size in each location is indicative. In order to avoid double counting equation’s sample size, the highest sample size for each location was selected without summing each equation sample size. The map is based on the data of April 2014 from www.globallometree.org Back to article page
