The most threatened plants receive the least scientific attention

PLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...
