Initial terrestrial vertebrate diversity assessment in upland
Cavite, Philippines
Ronaldo D. Lagat* and Rubie M. Causaren
ABSTRACT

Cavite’s remaining upland forest fragments are either remnants from commercial logging activities ca. 25-45
years ago or as a direct result of land conversions for agriculture or human settlements. These forest
fragments are very significant because they represent areas where pockets of wildlife habitat still remain. The
terrestrial vertebrates are often used to assess animal diversity because they are ideal biological indicators of
environmental change and anthropogenic disturbances. The study aimed to determine terrestrial vertebrate
diversity, conservation status, and identify major anthropogenic threats in these fragments. Terrestrial
vertebrates were surveyed using a combination of strip-transect sampling, time-constrained searches, visual
encounter survey (VES), and acoustic encounter survey (AES; for amphibians only), point counts, live trapping
and mist netting from October 2014 to March 2016. Species richness and biodiversity estimation were
computed using Shannon-Wiener Diversity Index, linear regression, detection and probability modeling using
PAST, and confidence limits for nestedness (0.05α) using EpiTools. A total of 175 terrestrial vertebrates were
documented and among the vertebrate groups, the birds had the highest observed diversity. Twenty-nine (19
birds, 3 mammals, 3 lizards, and 4 anurans) species are listed as threatened. Habitat loss and degradation
due to the conversion of habitats to agricultural and/or residential areas remained to be the most prevalent
threat in the remaining forested areas in upland Cavite. Baseline data generated shall be used in the different
government biodiversity monitoring activities as the basis for impacts and mitigation and initial planning for the
management and conservation of these remaining forest patches.
