The presence of different wildlife species enhances the value of the lake for recreational use. Several duck species are supported by the Lake. It supports 1% of the tufted duck (Aythya fuligula) population.

8 C. Regional and Local Setting Naujan Lake National Park (NLNP) in the northeastern coast of the island of Mindoro lies within the province of Oriental Mindoro. This eastern province of Mindoro is part of the Southern Tagalog Region and covers a total land area of 4, square kilometers representing about 9.30% of the region's land area. It is bounded on the north by the Verde Island Passage, by Maestro de Campo Island and Tablas Strait on the east and Semirara Island on the south; and by Occidental Mindoro on the west.Map of Oriental Mindoro
9 C. Regional and Local Setting The Park is bordered by the municipalities of1. Naujan in the north;2. Victoria in the west;3. Socorro in the south; and4. Pola in the eastThere are twenty-four communities or barangays within the park, divided into four municipalities. Five of these barangays are located in the municipality of Naujan, nine in Victoria, eight in Socorro and two in Pola. The local people use it as a communal fishing ground
10 C. Regional and Local Setting Its watershed is drained by theMacatoc, Borbocolon, Malayas, Malabo, Maambog, Malbog and Cusay Creek in the East,Bambang, Tigbao, and Tagbakin Creek in the West;Subaan and Singulan River in the South.The water of the lake exits via its lone outlet, the Butas River.The Naujan Lake watershed is about 30,000 hectares.Communities/Barangays within Naujan Lake National Park (NLNP)
11 D. Geology and Topography The geology of Naujan Lake watershed is associated with Pliocene to Quaternary volcanic (QV), Pliocene to Pleistocene marine and terrestrial sediments (N3 + Q1) and Recent Sediments (RS).The hill on the northeastern section of the watershed that is within the territory of Naujan and Pola is believed to have been built by Pliocene to Quaternary volcanic that consisted of non-active volcanic cone of generally pyroxene andesite including dacitic and/or andesitic plugs.The hills and the mountainous uplands in the southwest were the result of the uplift of the marine terrestrial sediments of limestone, pyroclastics, sandstone, siltstone, shale, and conglomerate during Pliocene and Pleistocene.Most of the low-lying and level floodplain areas in the northwest and southeast of the watershed were the subject of continuous deposition of recent sediments consisting mostly of alluvium, fluviatile, lacustrine, paludal and beach deposits that have accumulated in various quantities.
12 D.1 ClimateThe province of Oriental Mindoro has a Type IV Climate, i.e., no pronounced maximum rain period with a short dry season lasting from two to three months. Having been blessed with year round water supply, the province is ideal for agriculture.
13 E. Park BoundariesIn 1995, after conducting a series of studies and public consultations, the DENR Region IV through its Protected Area Suitability Assessment (PASA) Report recommended that the NLNP be categorized as a “protected landscape/seascape.”Protected landscape/seascape is defined under NIPAS as “areas of national significance, which are characterized by the harmonious interaction of man and land while providing opportunities for public enjoyment through recreation and tourism within the normal lifestyle and economic activity of these areas.”
14 F. Flora and Fauna, Habitats, and Ecosystems F.1 Vegetation/Flora of Terrestrial EnvironmentThe NLNP watershed originally belonged to three major vegetation types: (1) lowland dipterocarp forest, (2) mixed mangrove swamp-beach forest; and (3) marshland type, which ran in a north-south direction and occupied the western coastline of Naujan Lake.
15 F. Flora and Fauna, Habitats, and Ecosystems Parang type of vegetation (i.e., grassland - brushland type) prevalent in the vicinity of Butas River, from Barangay Bayani and passing through Barangays Laguna, Dao, and Sta. Isabel, all within the municipality of Naujan;Remnants of old-growth lowland dipterocarp forests which are sporadically present on steep hill slopes, ridgetops in the SW sector of the watershed zone as well as in ravines and precipices along the banks of Subaan River;
16 Mixed mangrove swamp-beach forest type present in the delta of Butas River in the boundary of Barangays Melgar A and San Jose I, Naujan;Marshland type of vegetation flanking the western coastline of Naujan Lake from its northern limit in the vicinity of Butas River’s mouth in Barangay Bayani, Naujan up to its southern limit in the vicinity of Barangay Pasi I, Socorro; and
