The given pie chart illustrates how plant species are endangered globally, whereas the bar graph showcases what level of risk they face in various environments.
Overall, it is clear that most plant species in the world are safe. Also of note is that tropical wet forests are the most dangerous place for plants, while the opposite is true in the case of deserts.
To elaborate, according to the former chart, more than half of plant species in the world are in safe condition (64.10%), far exceeding the 20.44% of vulnerable flora. The figures for endangered plants, those with insufficient data, and critically endangered ones account for insignificant shares of the total, at 6.92%, 4.62%, and 3.92% respectively.
Regarding the latter, 63% of endangered plants reside in tropical wet forests, nearly six times as much as the figure for tropical dry forests. The figures for dry savanna, tropical dry grassland, and wetlands are much lower, standing at 7.7%, 4.5%, and 4.3% respectively. Finally, tropical wet grasslands and deserts have the lowest rates of plant extinction, with figures not exceeding 2%.
