Woody plant encroachment is well-documented in savannas and could represent a significant anthropogenic carbon sink through the response of woody plants to increased atmospheric CO2 and manipulation by rangeland management.

Data from four continents suggests extreme drought events coincide with extensive tree death. An analysis of randomly located individual sites in an… CONTINUE READING
