Abstract

This study was conducted to determine sites that are suitable for the establishment of Falcata (Paraserianthes falcataria (Nielsen) plantations in Bukidnon, Philippines using Geographic Information System (GIS). GIS layers of variables such as soil, topography, climate and land use/land cover (lulc) were combined to generate the desired suitability map. A total of 2,076 Falcata plantation occurences distributed across the 22 municipalities needed for the validation of results were also collected. Results have indicated that among the 22 municipalities, the greatest number of occurrences (393) was found in Impasugong, while Kalilangan had the least with only 1 occurrence. Restricted areas (unsuitable) constitute 301,187 hectares or 33% of the total area of the province. These sites include protected areas, roads, built-up areas, lakes, rivers, and forests. Highly suitable, moderately suitable and marginally suitable constitute 22%, 44% and 1% respectively. It was also found that majority of the occurrence points coincide with highly and moderately suitable sites.
