Large trees store up to half the above-ground biomass in tropical forests, reiterating their importance in buffering against climate change, finds a study published in Global Ecology and Biogeography. The research, which involved dozens of scientists from more than 40 institutions, is based on data from nearly 200,000 individual trees across 120 lowland rainforest sites in Africa, Asia, and Latin America. It found that carbon storage by big trees varies across tropical forest regions, but is substantial in all natural forests.
