Fig. 4: The contribution of driving factors for changes in tree cover.
From: Mapping previously undetected trees reveals overlooked changes in pan-tropical tree cover
a is the relationship between the change of tree cover and the proportion of PUTC in pan-tropical, where the directions of the arrows represent the offset direction of the average coordinates of the samples in a specific grid type relative to the coordinate origin (0, 0), representing the main location of the samples of that type. b−f represents the relationship between the proportion of tree cover changes and the proportion of PUTC within different types of grids. g shows the contributions of human activities, climate change, and LUCC to the changes in tree cover in the pan-tropical region. This result was calculated from 61 independent samples selected at different spatial locations in the tropics. Data are presented as mean values ± SD.
