Biyo-Inusukan LCA

The forests of Inusukan and Biyo have been identified as priority areas for conservation in Patnanungan, Quezon.

Inusukan forest lies at the northwest portion of the island across the boundaries of barangays Amaga and Patnanungan Norte.

Biyo forest on the other hand is found towards the northeast portion of the island, adjacent to Inusukan forest, and is situated between barangays Kilogan and Patnanungan Norte.

The Biyo-Inusukan LCA spans the northern section of the mountain ridge of Patnanungan Island, and covers some flat low-lying areas on its western portion.

It has a total land area of 614 hectares and contains about 339 hectares of forest (or 55% of its land area). It is situated over four barangays, namely: Kilogan, Luod, Amaga, and Patnanungan Norte.

The largest portion of the total land Lumong-Tibalao LCA area of the LCA with 419.9 hectares (68.4%) is situated in Brgy. Patnanungan Lumong and Tibalao have also been identified as priority Norte, followed by Brgy. Amaga with areas for conservation in Patnanungan, Quezon. 159.3 hectares (25.9%), Brgy.

Rizal Wetlands LCA

Situated at the southwestern portion of Jomalig, the Rizal Wetlands covers the largest marshland found on the island. It is completely within the jurisdiction of Brgy. Talisoy, and is similarly confined to the Bigwangan Watershed.

The runoff from relatively higher sections of the watershed drains into the marsh (at Bigwangan River) before flowing out into the sea. Rizal Wetlands has a total land area of 207 hectares, composed mainly of wetlands. The size of the marsh is approximately 118 hectares (about 57% of the total area of the LCA).

Portions of the marsh include abandoned fishponds, formerly along the fringes where mangroves can be found. Some inland mangroves, grasslands, forest patches, and coconut groves are also found within the LCA, which surround the marsh. Grasslands are the second dominant vegetation within the LCA, covering 49 hectares (24%), while forests make up about 13 hectares (6%) and mangroves at 4 hectares (2%) of the Rizal Wetlands LCA.

The marshlands are ideal habitats and one of the country’s last remaining strongholds for the endemic and vulnerable Philippine Duck (Anas luzonica), and also serve as a habitat for the resident Wandering Whistling Duck (Dendrocygna arcuata).

The wetlands also support as a feeding The concept of a Local Conservation Area was originally ground for several migratory waders and developed in the Polillo Group of Islands to mainstream local shorebirds including various species of curlews, governments and other relevant stakeholders in the sandpipers, plovers, and the conspicuous Black- management of biologically important sites. The LCAs were winged Stilt (Himantopus himantopus). assessed as to their importance in terms of habitat functions to endemic species and ecosystems services, such as watersheds, In early 2013, the local government of and declared through participatory approaches using the Local Jomalig declared the Rizal Wetlands as a Local Government Code as the main policy framework. The LGUs passed ordinances declaring these LCAs. Conservation Area.

About 60% of or 958.8 hectares of the LCA in Lumong-Tibalao is forest land.

Aside from its significance in establishing a forest corridor for habitat restoration, Lumong- Tibalao also plays a key role in maintaining and improving watershed functions since it holds sizeable forest areas within several watersheds.
