Site description Mt Irid and Mt Angilo are located on the boundaries between the provinces of Bulacan, Quezon and Rizal, about 40 km to the north-east of Metro Manila, in the southern Sierra Madre mountains. Despite the close proximity to the city, there are very few roads into these rugged mountains, and they are sparsely populated. An extensive stand of what appeared to be old growth dipterocarp forest was located there (above 400 m) during a recent forest mapping survey (SOURCE?). Mt Irid rises to 1,448 m and Mt Angilo to 1,315 m, so there must be areas of montane forest around their peaks, but there are also likely to be substantial areas of lowland forest on the slopes.
