THE Ecosystems Research and Development Service of DENR Region V won third place in the search for Best Paper (research category) during the 20th Regional Research, Development and Extension Highlights conducted by the Bicol Consortium for Agricultural Resources Research and Development (BCARRD) at Camarines Norte State College in Daet, Camarines Norte last August 21, 2008. The winning paper, “Survey and Identification of Typhoon Resistant Reforestation Species” was presented by Science Research Specialist Alejo N. Balaguer. The study determined and compared the susceptibility of four reforestation species to typhoon damage; identified typhoon resistant reforestation species planted in the Bicol region; and developed a selection index for appropriate reforestation species in typhoon prone areas. Five different damage categories assessed were: defoliation, breaking of branches, breaking of stem, leaning and uprooting. Results of the study showed that agoho (Casuarina equisetifolia) was typhoon resistant; mahogany (Swietenia equisetifolia) moderately resistant; yemane (Gmelina arborea) and river red gum (Acacia auriculiformis) were non-resistant species.

        Based on the response of the four species to the different damage categories, an index of resistance was developed as guide in choosing species to be planted in typhoon prone areas. Mr. Balaguer explained that when practically applied to actual situation, a species-site matching for typhoon prone areas can now be possible. For instance, agoho can be safely planted in typhoon prone areas, even on top of mountains, while mahogany, yemane and river red gum would grow best in sheltered, low lying areas, he added.

        Dr. William Palaypayon, Regional Technical Director for Research, recommended that the selection index criteria developed in the said study be adopted by the government and private sectors involved in reforestation projects. He explained that cost of typhoon-related damages will be minimized if species are properly chosen. Furthermore, species currently used in reforestation programs, either exotic or indigenous be subjected to the same screening procedure.

        The two other major winners were from the Department of Agriculture for the study, “Optimizing Productivity in Rainfed Lowlands through Varietal Development” and Camarines Sur State Agricultural College for the study, “Management of Rice Blackbug in Camarines Sur”. Another eight papers were presented for development category. The RDE Highlights is an annual activity of BCARRD that provides an avenue for dissemination and discussion of research breakthroughs and significant findings to end-users. This was participated in by technology generators, communicators, extension workers, and policy-makers from various agencies and areas in the region.
