Fig. 1: Rates of recent change for all proxies of identified threats to trees.
From: More than 17,000 tree species are at risk from rapid global change
Human land use changes include cropland expansion (exp), tree cover decline (decl), built-up area expansion (exp), and deforestation. Climate change includes minimum and maximum temperature (Temp), vapor pressure deficit (VPD) and its seasonality (Seas), and precipitation and its seasonality (Seas). While the bars highlight the total number of species on a log10 scale, the colored lines show the kernel density estimates per conservation status group. Rates of recent change are expressed in percentages of the species’ extent per year, and for the climate variables the change is indicated by °C, Pa or mm change per year. Since this study on recent change rates has been done with data ranging from ~2000 and ~2020, one should keep in mind that the total amount of change over this time period should be multiplied by ~ 20: where a 2% decrease in extent may not seem relevant, a 40% decrease during the last 20 years can be quite alarming. The vertical gray line indicates no change. At the bottom of each plot, colored dots indicate rates of recent change per conservation status group when only one species has that value and black ticks identify the 5th and 95th quantile.
