The Philippines hosts a wide range of wetland types, classified as inland, coastal and human-made wetlands. These diverse types of wetlands benefit the country and its people through its support to the diversity of ecosystems and the resources within, while performing an array of ecosystem services. The direct and indirect benefits include those critical for human survival, such as being the source of drinking water, food, shelter, and livelihood activities, as well for adaptation and mitigation from disasters like flood, storm surge, tsunami and drought. Few examples of these wetlands and the benefits they provide are: the Taal Lake, is known for the “Tawilis” (Sardinella tawilis) which is found nowhere else in the world, and the delicious “Maliputo” (Caranx ignobilis) which may be the same species as the ordinary “Talakitok”, but is valued more when grown in the lakewaters of Taal; the scenic and geological beauty of the wetland complex composing the Puerto Princesa Subterranean River, which has captured the attention of both national and international tourism industry; the coastal lagoons, marshlands, and mangroves of the Las Piñas-Paranaque Critical Habitat and Ecotourism Area, which has hosted various waterbirds, enough to be considered a worthy bird-watching paradise in an urban setting; and the vast mangrove stands of Guian, Samar, which studies had proven, had much dissipated the impact of storm surges during the typhoon “Yolanda” to adjacent communities.

The Biodiversity Management Bureau, along with its many efforts to instill awareness on the importance of these invaluable wetlands, had embarked on a Wetlands Conservation Program which includes the identification, inventory, profiling, as well as management plan preparation and implementation of the many wetland habitats in the country. The Atlas of Inland Wetlands in Mainland Luzon, Philippines is a major step in fulfilling the objectives of this Program. Once the list of wetlands in the whole country is updated, baseline information on the location and types of wetlands can better inform policies and/or site specific management decisions or interventions.

The Atlas is intended to be a user-friendly reference presented in thematic and composite maps. Although limited to inland wetlands, and to the mainland of Luzon, it provides an initial structure to build on a complete nationwide wetland database and mapping system. It contains 756 inland wetlands, classified into lakes, swamps/marshes, rivers and river systems, water storage areas and ponds which are presented in eight (8) thematic maps, including a map of potential Ramsar sites. It is also provided with clear maps which can be manually overlain into the thematic maps to identify locations of wetlands within different conservation schemes and prioritization such as the National Integrated Protected Area System, Critical Habitats and Key Biodiversity Areas.

The development of the Atlas further warranted the conduct of a more comprehensive and ground-verified wetlands inventory. In addition, to complete the effort in mapping out all the wetlands in the country, it is envisioned to become a continuing DENR activity, which would proceed with the inland wetlands in Visayas and Mindanao, including the smaller islands.

With this, I would like to extend our heartfelt thanks to the Ramsar Regional Center-East Asia for the support and for all those who extended their assistance to make this publication possible.

Let us wisely use our wetlands. Wetlands are our main source of water and water is life.

Wetlands are areas of marsh, peat or water whether natural or temporary, with water that is static, flowing, fresh, brackish, or salt, the depth of which at low tide does not exceed six meters. It is classified into coastal wetlands (tidal flat, reef flat, seagrass bed, saline lagoon and mangrove), inland wetlands (estuary, river, marsh, swamp forest and lake), and, human-made wetlands (irrigated ricefield, fishpond and dam).

The Philippines, consisting of more than 7,000 islands and islets, has a wide range of wetland types. It is composed of three (3) major islands, Luzon, Visayas, and Mindanao, which is divided into 17 administrative regions. Luzon is the largest island covering eight (8) administrative regions, namely, Cordillera Administrative Region (CAR), National Capital Region (NCR), and Regions I to V, with Region IV divided into IV-A and IV-B.

The Atlas of Inland Wetlands in Mainland Luzon, Philippines is a preliminary updating of existing inland wetlands in the country. It focused on mainland Luzon and excluded Batanes and some islands in Cagayan of Region II; some islands in Quezon of Region IV-A; all provinces of Region IV-B; and, Catanduanes and Masbate provinces of Region V. The information in the Atlas was generated from existing BMB list of wetlands, interview results, and published and unpublished literature. The location of the wetland sites were mapped using Geographic Information System. Data validation was done through consultation-workshop, coordination with concerned agencies and DENR Regional Offices, and to some extent site visit.

A total of 756 inland wetlands were identified in mainland Luzon. Out of these, 86% are rivers and river systems; 11% are lakes; 2% are human-made (dams); and about 1% are marshes, swamps and ponds. Four hundred ninety two (492) inland wetlands were identified within National Integrated Protected Area System (NIPAS) sites, declared Critical Habitats, Key Biodiversity Areas, and potential Wetlands of International Importance or Ramsar Sites
