This IBA is in a range of low hills on the border between the densely populated provinces of Cavite and Batangas. The proposed National Park has three peaks, Palay-palay, Rico de Loro and Mataas na Gulod. The last remaining lowland evergreen rainforest in the Province of Cavite is on Mt Palay-palay in the northern portion of the park, and this habitat is reported to cover c.60% of the park. It is mainly forest on limestone. There are also areas of arable land, small settlements and rural gardens, and some kaingin.
There is no information available on the birds of the Mt Palay-palay / Mataas na Gulod National Park, but there are a few old records of threatened and restricted-range species from nearby. This IBA is likely to support several of the lowland specialist birds of the Luzon Endemic Bird Area, and it may prove to have a similar avifauna to that of Mt Makiling (PH022).
Non-bird biodiversity: No mammalian and herpetofauna surveys have been done in the area.
