Preliminary Collection and Inventory of Crustose and Physcia Species Diversity in Mount Hamiguitan, San Isidro, Mati, Davao Oriental

A preliminary survey of lichen diversity in Mount Hamiguitan Range Wildlife Sanctuary identified seven species across four families, with Physciaceae emerging as the dominant group. The study, conducted at approximately 1,200 meters above sea level, revealed a moderately diverse and ecologically balanced lichen community, characterized by indices suggesting stability typical of montane ecosystems. Researchers collected specimens from substrates such as tree trunks, rocks, and decayed logs using transect lines, documenting morphological characteristics validated by a specialist. The findings highlight the site's rich lichen flora, emphasizing the need for continued biodiversity monitoring to inform conservation efforts in this protected area.
