Descripción
Riparian and aquatic ecology within the mountainous portion of the Lower Agno Watershed Forest Reserve (LAWFR) were investigated to generate scientific data for a sustainable and resilient ecosystems in Tuba, Benguet, Philippines. Participatory approach was implemented with the collaborative support Department of Environment Natural Resources, local government units, private companies and local communities including indigenous peoples. The overall riparian plants identified were 69 species, 24 families of angiosperms, 1 gymnosperm, and 6 pteridophyte groups. Nine were reportedly known as invasive, indicating level of disturbance along rivers. Aquatic life forms in all five rivers comprised of 28 phytoplankton genera under 4 phyla (Bacillariophyta, Charophyta, Chlorophyta, and Cyanophyta), where Chlorophyta was found frequently occurring and highly dense. Zooplankton consisted of 12 taxa, with one new species listed onsite as Brachionous angularis. Seventeen periphyton taxa under 4 phyla (Bacillariophyta, Chlorophyta, Cyanophyta, and Xanthophyta) were recorded. Twenty-one macrobenthos species under 12 major taxa were identified. Higher number of phytoplankton species was generally found during dry season in all sampling sites, while zooplankton was less abundant during dry season. Balog River was the only one with periphyton species across sites and sampling periods. Macrobenthos Ephemeroptera-Plecoptera-Trichoptera index was used to determine health status of the environment.
