The ubiquitous boyo-boyo, an invasive tree species common in the mountains of Mindanao, could be economically and environmentally beneficial after all if managed properly.
Dr. Thomas L. Cardente, a forester at the Department of Environment and Natural Resources – Region 12, bared this in his study on the potentials of boyo-boyo or spiked pepper tree (Piper aduncum) as part of his doctoral dissertation research.
Cardente revealed results of his research in a recent seminar organized by the Los Baños-based Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) headed by Dr. Gil C. Saguiguit Jr.
His seminar is based on the results of his PhD dissertation research entitled “A Management System for Watersheds Dominated by Spiked Pepper in Southern Mindanao, Philippines” that was funded by SEARCA through its PhD research scholarship.
Spiked pepper tree is a native tropical American species that was introduced in the southern part of the country through bird migration. It is considered an invasive tree that dominates forests, rocky terrain, and former cogon and hagonoy (a weed) areas in some parts of Mindanao.
Despite its now ubiquitous presence in Mindanao, very little information is available on spiked pepper tree. This prompted Cardente to study the species, particularly its potential in reforestation and watershed management.
In a statement released by SEARCA, Cardente noted that as boyo-boyo can overrun vast swaths of cogon and other fire-prone and less-useful grasses and weeds, it can improve the micro-climate in such areas and thus help mitigate climate change. [Bong S. Sarmiento / MindaNews]
