Survey and Characterization of Edible Fruit and Ethnomedicinal Trees in the Forest Landscape of Apayao Province

Abstract

This study was conducted in the six municipalities of Apayao Province, namely, Luna, Pudtol, Flora, Conner, Kabugao, and Calanasan. This aimed to survey and characterize the edible fruit and ethnomedicinal trees in the forest landscape of Apayao province. It determined the geographical location, morphological characteristics, ecological status, DNA sequencing, phytochemical contents, uses, and threats of the edible and ethnomedicinal trees in the forests of Apayao. The methods used were qualitative and quantitative research. Fifteen (15) edible and 10 ethnomedicinal trees were surveyed with sixteen (16) families were identified.Out of 25 edible and ethnomedicinal trees, the conservation status is endangered, threatened, rare, vulnerable, and least concerned. Out of 25 edible and ethnomedicinal fruit trees, most are with identity results that range from 93 to 100% identity. Flavonoids, tannins, and sapotin compounds are mostly present in edible and ethnomedicinal trees. The community members are using 15 different ethnomedicinal trees to address 32 health-related conditions. The results of the phytochemical analyses provide support evidence to support the traditional uses of ethnomedicinal trees. All surveyed trees are susceptible to pests, diseases, and destruction brought by natural phenomena such as the effect of climate change. A policy recommendation for the conservation and protection of edible and ethnomedicinal trees is then proposed.
