Butardo, M.Z.M.
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. Cultivation decreased soil pH, organic matter content and total nitrogen and available phosphorus and potassium of the soil. Kaingin-making has resulted in the lowering of species diversity and change in growth form and species composition from woody to herbaceous and from forest to grass dominated stands
