A world map of plant diversity

Why are there more plant species in some places than in others? Why is diversity highest in the tropics? What is the connection between biodiversity and environmental conditions? To help answer these questions, an international team has reconstructed the distribution of plant diversity around the world and made high-resolution predictions of where and how many plant species there are. This will support conservation efforts, help to protect plant diversity and assess changes in the light of the ongoing biodiversity and climate crises.
