TOPOGRAPHY
Cavite is divided into four (4) physiographical areas, namely: the lowest lowland area,
lowland area, the central hilly area and the upland mountainous area.
The lowest lowland area is the coastal plain in particular. These areas have extremely low
ground level of EL. 0m to EL. 2m compared to the high tide level of about EL. 0.8m from the
Mean Sea Level (MSL). These are the municipalities of Bacoor, Kawit, Noveleta and Rosario.
The lowland area consists of the coastal and alluvial plains. These areas have flat ground
slope of less than 0.5% and low ground elevation of EL. 2m to EL. 30m. The alluvial plain can
be found in the municipality of Imus and southern part of General Trias. Into these
municipalities forms the transition area between the coastal plain and the central hilly
area. It also covers some areas of Bacoor, Kawit, Noveleta, Rosario and Tanza.
The third topography type is the central hilly area, generally found on the mountain foot
slope. It forms the rolling tuffaceous plateau. This topography includes steep hills, ridges and
elevated inland valley. The plateau is characterized with ground elevation ranging from
30m to nearly 400m. Its ground slope ranges from 0.5 to 2%. The city of Trece Martires and
the municipalities of Dasmarias, Indang and Silang have this kind of topography.
The last topography type is upland mountainous area, found in Amadeo and Tagaytay
City. They are situated at a very high elevation above EL. 400m with slopes of more than
2%. The Tagaytay ridge has a peak elevation of 650m.

8.72 percent of CALABARZONs total land area, 2.74 percent of the
regional land area and 0.48 percent of the total land area of the
Philippines which is 299,404.00 hectares. The municipalities of Maragondon
and Silang have the biggest land areas comprising 16,549 hectares and
15,641 hectares, respectively while the municipality of Noveleta has the
smallest land area as indicated by 541 has. or 0.38 percent of the
provincial total land area (Table 3.2).

Forest Lands
Cavite Province lies in the western monsoon forest zone. This location is
very beneficial for the formation of tropical rain forests which are
characteristically made through natural vegetation. In 2007, the
existing forest area within the province totalled to 8,624.956 hectares.
These forest areas were categorized as Protected Landscape under
R.A.7586 otherwise known as National Integrated Protected Area
System (NIPAS) and the unclassified forest (Non-NIPAS). By virtue of
Proclamation Number 1594 on 26 October 1976, a total of 4,000
hectares located in Ternate and Maragondon, Cavite was
proclaimed as national park, now known as the Mts. Palay-Palay and
Mataas na Gulod Protected Landscape. The park lies in the border of
Cavite and Batangas and has three peaks, Palay-Palay, Pico de Loro
and Mataas na Gulod. Still, there were five (5) unclassified forests
found along Tagaytay Ridge, Maragondon, Magallanes, Ternate and
Alfonso (Table 3.3). With regards to the records of mountains, seven
were named such as Pico de Loro, Mt. Palay-Palay, Mt. Buntis, Mt.
Mataas na Gulod, Mt. Nagpatong, Mt. Hulog and Mt. Gonzales (Table
3.4).
The richness of Cavites forest provides the abundance of different
forest products (Table 3.5). Grass in nature, bamboo, is one of the most
available forest products being found in the municipalities of Ternate,
Magallanes, Maragondon and General Aguinaldo throughout the
year.

As mentioned earlier, Cavite lands are divided into two classifications, forest lands and
alienable and disposable lands. These lands are being used in various ways, either for
agriculture, residences, open areas, etc. These actual uses are termed as land-use.
Based on the Cavite Provincial Physical Framework Plan 2005-2010, Cavites alienable and
disposable lands are further classified into production lands and built-up areas. Production
lands in Cavite are intended for agriculture, fishery and mining. On the other hand, built-up
areas are mainly for residential areas, commercial, industrial and tourism areas.
Production Land-Use
Majority of production land-use is into agriculture. Considering that 50.33% of the total
provincial land area is engaged into agriculture, it can be generalized that in spite of rapid
urbanization in the province, Cavite remains to have an agricultural economy that makes
food security attainable. Some of the major crops being produced in the province are rice,
corn, coffee, coconuts, cutflowers and vegetables.
Included in the agricultural land use are livestock farms that range from piggeries, poultries,
goat farms and cattle farms. The climatic suitability of Cavite makes the province ideal for
integrated farming, having crops and livestock rising in one farm.
Fishery is also another major component of the agricultural sector. Having rich marine
resources and long coastlines, the province is home to numerous fishery activities. This
industry has provided livelihood to many Caviteos. In some lowland and even upland
areas, fishery, in the form of fishponds are also producing considerable amount of fish
products. Some areas in Cavite are also engaged in fish processing and production of fish
products like fish sauce.

Mining is the third component of production land-use in the province. As of 2009, there are
15 mining and quarrying areas operating in Cavite. Extraction includes filling materials,
gravel and sand.

The Province is dominated with production area that accounts for 50.33% of its total land
area. It is followed by built-up areas that cover 39.99% of Cavite. Lastly, 9.33% of the
province is considered protection lands such as natural parks and forests.
Maragondon and Silang are relatively agricultural municipalities with 10,266 and 9,732
hectares of production land, respectively. Tanza, Imus and Gen. Trias are the municipalities
with most area intended for urbanization. Meanwhile, despite relatively small land area,
Bacoor and Trece Martires City are dominated with built-up area with only 604 and 523
hectares considered as production land, respectively (Table 3.6).

SOIL
Cavite is composed of several soil types according to soil surveys conducted by the Bureau
of Soils and Water Management (BSWM). Classification of soil types in a specific area is a
very important consideration in identifying its most fitted land-use. This way, utmost
productivity can be achieved.
The lowland area of Cavite is generally composed of Guadalupe clay and clay loam. It is
characterized as coarse and granular when dry but sticky and plastic when wet. Its
substratum is solid volcanic tuff. These types of soils are suited to lowland rice and corn while
those in the upland are suited for orchard and pasture. Guadalupe clay adobes are
abundant in the southern part of Bacoor and Imus bordering Dasmarias. The soil is hard
and compact and difficult to cultivate that makes it generally unsuitable for diverse
cropping. It is very sticky when wet and granular when dry. Forage grass is advised for this
type of soil. Hydrosol and Obando sand are found along Bacoor Bay. The shoreline of
Rosario, Tanza, Naic and Ternate are lined with Guadalupe sand.
The central area principally consists of Magallanes loam with streaks of Magallanes clay
loam of sandy texture. This is recommended for diversified farming such as the cultivation of
upland rice, corn, sugarcane, vegetables, coconut, coffee, mangoes and other fruit trees.
The steep phase should be forested or planted to rootcrops. The eastern side of Cavite is
consists of Carmona clay loam with streaks of Carmona clay loam steep phase and
Carmona sandy clay loam. This type of soil is granular with tuffaceaous material and
concretions. It is hard and compact when dry, sticky and plastic when wet. This type of soil
is planted to rice with irrigation or sugarcane without irrigation. Fruit trees such as mango,
avocado and citrus are also grown in this type of soil. Guingua fine sandy loam is found
along the lower part of Malabon and Alang-ilang River at Noveleta.
The type of soils that dominate the upland areas are Tagaytay loam and Tagaytay sandy
loam with mountain soil undifferentiated found on the south-eastern side bordering Laguna
province. Also on the southern tip are Magallanes clay and Mountain soil undifferentiated
with interlacing of Magallanes clay loam steep phase. The Tagaytay loam contains fine
sandy materials, moderately friable, and easy to work on when moist. In an undisturbed
condition, it bakes and becomes hard when dry. About one-half of this soil type is devoted
to upland rice and upland crops. On the other hand, Tagaytay sandy loam is friable and
granular with considerable amount of volcanic sand and underlain by adobe clay.
Mountain soil undifferentiated is forested with bamboos found in the sea coast. Cavite also
has the Patungan sand characterized by pale gray to almost white sand with substratum of
marine conglomerates which are found at Sta. Mercedes in Maragondon and in some
coastlines of Ternate.

THE MOUNTS PALAY-PALAY AND MATAAS NA GULOD PROTECTED LANDSCAPE
Cavite is very fortunate to have an area which is considered to be a biologically rich. In
1976, by virtue of Presidential Proclamation No. 1594, the Mounts Palay-Palay and Mataas
na Gulod were declared to be national parks. The declaration aims to preserve the natural
biodiversity of the area as part of the advocacy to preserve the countrys natural heritage.
The national park was later named as the Mounts Palay-Palay and Mataas na Gulod
Protected Landscape.
4.
This is an area with significant habitat and specie value. This zone is subjected to
management practices so as to maintain specific condition or habitat for rare,
threatened and endangered species. Human habitation and sustainable use
maybe allowed if they play a habitat management role. A portion of the stretch
of the Palicpican River is located in this zone.
The entire landscape is composed of more or less 4,000 hectares. The preservation of its
natural biodiversity is a strategic move considering the rapid urbanization happening in the
province of Cavite and the nearby Metro Manila. Known to be a good source of water, it is
of utmost importance to preserve and rehabilitatethe damaged portions of the national
park.
The national park is approximately located within the geographic coordinates of 14o12 to
14o17 north latitude and 120o38 to 120o42 east longitude. The park covers four (4)
barangays (Sapang, Pinagsanhan, Patungan and Papaya) and seven (7) sitios (Malauyas,
Caynipa, Caytako, Cacabay, Magabe, Murangdalig and Hamilo). Different portions of the
park can be found in three municipalities (Ternate, Maragondon and Nasugbu) under two
provinces (Cavite and Batangas).
5.
The Mounts Palay-Palay and Mataas na Gulod Protected Landscape Management Zones
The Park is divided into 10 management zones that ensure a balanced land-use for the
park. These are as follows:

REFORESTATION PROJECTS
In order to maintain and enhance the natural resources of the Province, the Department of
Environment and Natural Resources in coordination with the Provincial GovernmentEnvironment and Natural Resources Office are conducting various reforestation projects.
Reforestation projects are concentrated in municipalities where protected areas currently
exist like in Maragondon and Ternate. It is in these two municipalities where the Mts. PalayPalay and Mataas na Gulod National Park can be found. These areas also made possible
the presence of bulk-water resource in Cavite and thus, have to be maintained.
