Occupancy of the land grant and the use and condition of its forest and land resource have changed the settlers' lifestyle; affected their income, nutrition and health conditions and impacted on community relationships as well as on the University of the Philippines' administration of the area. Reforestation through kaingin-making, charcoal-making and carabao-logging has resulted in the changes in microclimatic conditions.
