NEW FOREST FRONTIERS for: Jobs, Permanent Communities, A Stronger Nation FORESTED WATERSHEDS deliver clear, pure water to cities and towns and to irrigation projects and power plants.

BUT WHEN rain falls on denuded slopes, there is no vegetation to intercept it, no litter on the ground to retard the run-off.
