A preliminary report on the diversity of foliage arthropods of Quezon National Forest Park, Quezon, Philippines

Abstract

Quezon National Forest Park is composed of secondary and old growth forests. However, the park is located close to human dwellings and the national highway runs through part of the park as well. Arthropod diversity monitoring was conducted in the area to assess the effects of anthropogenic activities as indicated by terrestrial arthropod diversity. Foliage arthropods were assessed mainly by sweep net sampling at four plots along a 2-km transect. Diversity indices were high in comparison with previous values generated from nearby agricultural communities. The high diversity of forest foliage-dwelling arthropods in the park may be largely due to the diverse vegetation even among patches of secondary growth. Arthropods, as expected, depend largely on the surrounding vegetation for their food and habitats in which they spend various activities ranging from foraging, resting, mate-finding and mating to egg laying, etc. The trends in the biodiversity indices of foliage dwelling arthropods provided baseline data for comparison on the possible effects of human activities, including power-generation, on the surrounding agricultural and other disturbed ecosystems.
