This proposal will use the collaborative, participatory, multi-disciplinary and multi-stakeholder approach to encompass the terrestrial ecosystem in Mt. Agad-agad, Lanao del Norte. To implement this program, the Center for Biodiversity Research and Extension in Mindanao (CEBREM) has been designated by DOST Mindanao cluster as the Mindanao Biodiversity hub. This research has chosen Mt. Agad-agad, Lanao del Norte focusing on biodiversity of the flora to elucidate the species richness, assessment and conservation with trained local researchers. The flora component as detailed herein will include the vascular plants (angiosperms, gymnosperms, ferns and lycophytes) and non-vascular plants (mosses, liverworts and hornworts). Moreover, the forest conservation and management, stakeholder’s roles, policies and needs will be assessed for sustainable development. High biodiversity sites will be identified for possible ecotourism destinations. This project will fill gaps in the biodiversity management frameworks steered by Department of Environment and Natural Resources (DENR) through studying the ecosystems in a landscape approach, which will involve the biodiversity and forest condition assessments. Interrelated data will be obtained which will serve as bases for policy-making bodies in formulating policies relevant to biodiversity conservation and ecotourism development. Likewise, capacitating stakeholders will ensure sustainability and will be a great step in monitoring and conserving the remaining threatened, endemic, economic/iconic species and their habitats. Outputs of this research project are useful to conservationists, local government units, academic institutions, indigenous cultural communities and policy-making bodies for sustainable ecotourism, protection and conservation of important biological resources and capacitate stakeholders for long-term and sustainable activities
