GENERAL DESCRIPTION
The Mariveles Mountains
are in southern Bataan province, near the entrance to Manila Bay, and
rise steeply from sea level to 1,420 m. An area of forest is shown there
on recent forest cover map;s, which is reported to include both lowland
and montane forest, including mossy forest. This includes old reforestation
plantations in the former Lamao Arsenal and old growth forest at the peak
of Mt. Mariveles.

| Ijima's
Leaf-warbler (Phylloscopus ijimae) |

record of this non-breeding visitor from Japan. |

as rare. |
| White-lored
Oriole (Oriolus albiloris) |
R |

and 1961 respectively. |
| Isabela

were collected along the Lamao River, 5 km inland from Manila Bay,
in 1947, and at Mariveles in the early 20th century. |
Many of the threatened
and restricted-range birds of the Luzon Endemic Bird Areas have been recorded
in or near to this IBA, but there is little recent information on their
status there. This is the only site in the Philippines where Ijima's Leafe-warbler
has been recorded, although this species is difficult to locate and identify
and presumably also winter elsewhere in the islands. It is also notable
for the records o the highly threatened Isabela Oriole, and this species,
Luzon Striped-babbler and Furtive Flycather appear to have unusual disjunct,
being recorded from the Bataan peninsula and the Sierra Madre in eastern
Luzon. However, this may prove to be a result of gaps in the coverage
of some other parts of Luzon by ornithologists. A subspecies of Elegant
Tit, Parus elegans gilliardi, is only known from the Bataan peninsula..
CONSERVATION ISSUES
Potential threats
to this IBA include exploration for mining, should applications be approved.
Surveys are required
in this IBA, to investigate both the extent and quality of the remaining
habitats and the current status of the threatened and restricted-range
birds and other biodiversity.
