Naujan Lake
GENERAL INFORMATION
Area
: 21, 655.00 hectares
Legal Basis :
Proc. No. 335 dated January 25, 1968
Boundaries and Geographical Location
Naujan Lake National Park is bounded by the Municipalities of Naujan in the north,
Victoria in the west, Socorro in the south and Pola in the east. NLNP lies between
1304 to 1315 North latitude and 12017 to 12027 East longitude. It is located
in the northeastern coast of the island of Mindoro Island which is under the
administrative jurisdiction of the Province of Oriental Mindoro.
Historical Background
Naujan of Nauhang as the elders spoke it and how early European cartographers
spelled it, was coined even before the arrival of foreigners to the island of Mindoro,
then known to the Spanish as the island of Mina de Oro (mine of gold) and to some
Chinese scholars as Ma-i (country north of Borneo) and Min-to-lang (important port
along the coast) to others. The name Naujan was, according to some, derived from
the local legend of Nauhaw si Juan (literally Juan was Thirsty), the validity of
which is still uncertain.
The lake and its watershed are endowed both with natural beauty and with rich
biodiversity. The lake also performs numerous ecological functions, serving as
home, breeding ground and refuge and as integral part of the migratory route of
wildlife.
Accessibility
NLNP can be reached by bus for about two and a half (2 ) hours from Manila to
Batangas City. Another two (2) hours by boat going to Calapan Pier and 45 minutes
bus/jeep ride going to the Park. The Park is highly accessible by land transportation
from Calapan to Pasi, Socorro and various points of the lake and vicinity except in
places/barangays alongside the lake which is accessible only by motorized banca.
Conservation Status
Key Biodiversity Area; Ramsar site
Anatidae Site Network in May 1999
PHYSICAL FEATURES
Topography and Physiography
The portions of the area of Pola, Naujan and Socorro are rolling or hilly and
mountainous; Victoria and few portions of Socorro are relatively flat. NLNP has a
highest elevation of 300 meters above sea level and has a lowest depth of 50
meters from the surface water level of the lake.
Almost half of the Naujan Lake watershed has level to undulating slopes (0 to 8%).
Approximately 90% of these lands are used for paddy production of the remaining
10% are identified as swamp areas adjacent to the lake.
Climatic Condition
It falls under the Type III climatic condition which has no pronounced maximum rain
period with a short dry season lasting from two to three months. Having blessed
with year round water supply, the province is ideal for agriculture.
Hydrological Features
Naujan Lake is the fifth (5th) largest lake in the Philippines with an area of 8,125
hectares, rising 20 meters above sea level with a maximum depth of 45 meters. Its
watershed which covers about 30,000 hectares is drained by the Macatoc,
Borbocolon, Malayas, Malabo, Maambog, Malbog and Cusay Creek in the East, by
Bambang, Tigbao and Tagbakin Creek in the West, Subaan and Singulan River in the
South. On the other hand, the water of the lake drains via its lone outlet, the Butas
River flowing towards Tablas Strait with an outlet at Barangay Lumang-bayan,
Naujan which is located at the north of the Park.
BIOLOGICAL FEATURES
Flora
NLNP watershed has three major vegetation types: 1) lowland dipterocarp forest; 2)
mixed mangrove swamp-beach forest; and 3) marshland type. NLNP watershed
remains relatively rich composing of 613 vascular plant species distributed into 433
genera and 105 families. About 72% of the total floral species present in the whole
watershed zone are native or indigenous, 15% Philippine endemic and 13%
introduced or exotic. The present flora is composed of 46 fern species, 43 grasses,
147 herbs, 67 shrubs, 50 vines, 34 lianas, 91 medium-sized trees and 31 large
trees.
The trees bordering the lake are: dao, dita, balete, nato, amugis, red lauan and
taluto. Other tree species in the Park are ipil-ipil, golden shower, bagras, durian,
kape, acacia, talisay, anonang, pili, among others. There are also herbal species
that can be used as indigenous medicine for various ailments such as atsuete,
camaria, ikmo, sambong, albutra, and oregano.
Fauna
In 1997 Resource Profiling, a total of 98 species of vertebrates, 5 species
amphibians, 12 reptiles, 68 avian fauna and 13 mammals were recorded. Among
reptiles and amphibians, three (3) species are endemic to the Philippines and the
rest are introduced and native species. Of the 68 avian species, 22.6% or 15
species are endemic to the Philippines and 2.94% or two species are endemic to the
Island.
NLNP is also home to at least 15 species water birds. Aythya merila or tufted duck,
locally known as Pato China is by far the most sought after water bird because of
its meat value. Winter visitors such as Egretta garzetta and Dendrocygna
acruata and some avian species use the swamp for breeding if not as a permanent
habitat. Likewise, there are game birds that are abound in the area which include:
Podiceps unigricollis (grebes), Anas luzonica (mallard), Amauronis olivaceus
(swampeas), Gallimula sp. (rails/gallimules), Rallimae eurizonsides (crokes),
Dendrocyna arcuata (lesser fuluous whistling duck. Non-game birds include: Ardea
purpurea manilensis (purple heron), Bubulaes ibis coromandus (cattle egret),
Ixdorychus cinnamoneus (cinnamon least bittern), Falcaniformes (hawks),
Lake Naujan
| back | HOME |
Naujan Lake is the fifth largest lake in the Philippines. It is found in the northeast coast of the
province of Oriental Mindoro on Mindoro Island; the island is in itself considered a discrete
biogeographical region. The lake is 14 kilometers long and 6 kilometers wide and is bounded by the
municipalities of Naujan, Pola, Victoria and Socorro. The lake is home to rich ethnic and cultural
diversity. The population is composed of the Mangyans, indigenous people of Mindoro including the
Tadyawan tribe in the area of the lake, and the damuong or
non-Mangyans.
Naujan Lake is a wetland known for its rich biodiversity.
Protected fish species such as Mugil dussumieri, Caranx
sexfasciagus and Lutianus argentimaculojus, and various
harvestable species.
The lake is an important feeding or wintering ground for
large numbers of ducks and other waterbirds such as herons,
egrets, terns, rails and bitterns. The rare Amaurornis
olivaceous is a resident-breeding species found in the area.
The endemic Philippine Crocodile Crocodylus mindorensis, a
critically endangered freshwater crocodile, was recorded, but
may now be extinct on Mindoro.
