Abstract
It is proposed to hold two workshops at NCEAS, in March of 1998 and 1999 respectively, to test and unify the emerging theory which accounts for the partitioning of Net Primary Production (NPP), and the co-existence of trees and grasses, in mixed tree-grass systems. The workshops would apply four savanna models, which reflect a range in complexity in the way they treat the tree-grass interaction, to thirty data sets from widely differing environments, in three experiments which will critically test the interaction theory. The effort is part of a SCOPE project which has identified a multinational team, the models and the datasets.
