Bhutan Local Studies
Presented below are early results from a study conducted by the Jakar lab to understand something about the impacts of grazing on forest growth. This is a very difficult question to ask in Bhutan for there are few forests, near settlements, that are devoid of grazing impacts at one time or another. Exclusion and inclusion studies are being designed now to include tree-ring analysis. This first study looked at tree-growth response for a 5 year period (1990=1995) when the number of grazing bulls was regulated within a fenced enclosure. Trees within and outside the enclosure were sampled and their growth compared.
