The present study was conducted to compile information on species composition of moths found from Mt. Musuan, Maramag, Bukidnon. The moths were collected using a light trapping method from November to December 2014 on three vegetation types namely grassland, pine trees and mixed dipterocarp vegetations of Mt. Musuan. The study revealed the presence of 29 species belonging to 11 families and 24 genera. The species abundance was recorded highest in mixed dipterocarp vegetation with 6.681 mean individuals, followed by in pine tree vegetation with 3.085 mean individuals and 1.723 mean individuals in grasslands. Sixteen (16) species are randomly distributed which includes Asota Hubner, Amerila Walker, Carriola ecnomoda Swinhoe, Creatonotos gangis Linneaus, Nyctemera baulus Boisduval, Oenistis altica Linnaeus, Gastrina cristaria Guenée, Pingasa chlora Stoll, Taxeotis sp. 1 Guest, Hypomecis Hubner, Pingasa ruginaria Guenée, Pinara sp. 1 Walker, Persectania dyscrita Common, Noctuidae sp. 1 Latrielle, Dudusa Walker and Ourapteryx Leach. Therefore, Mt. Musuan is a home of 29 species of moth belonging to twenty-four (24) genera and eleven (11) families. There are 16 species species of moths that are randomly distributed. Less

Forest litter is an important aspect for healthy forest ecosystems. Hence, this study monitored the litterfall production and turnover in the established two-hectare permanent plots in the three Long Term Ecological Research (LTER) Sites in Mindanao, viz., Mt. Apo, Mt. Hamiguitan and Mt. Musuan. Litter samples were collected from 2w0 installed traps at each site and consequently sorted to components, processed and oven-dried. Data revealed that the estimated annual litter production was highest in Mt. Musuan with 11211.5 kg ha-1, followed by Mt. Apo with 6648.0 kg ha-1 and Mt. Hamiguitan with 4919.5 kg ha-1. Agathis philippinensis contributed the highest litterfall production in Mt. Apo, whereas Barringtonia racemosa and Artocarpus blancoi in Mt. Hamiguitan and Mt. Musuan, respectively. Highest litter turnover was observed in Mt. Musuan (5.35%/day). Litterfall production showed to have a positive correlation with temperature for Mt. Hamiguitan and Mt. Musuan. Among the studied sites, Mt. Musuan had the highest forest primary production. Results of this study support previous reports that lowland forests have high forest productivity. Further, there is a need to plant Philippine endemic and threatened trees, such as A. philippinensis since these prove to have high productivity as in the case of Mt. Apo and Mt. Hamiguitan. Less
