Jerejak, an island covered with thick coastal
forest aging approximately 4,000 years, hosts about 210 species and 71
families of plants. Many types of plant communities can be found here,
the main ones are Dipterocarp & Mangrove Swamps.
DlPTEROCARP
Dipterocarp is a timber species found on hilly areas of the island. It
usually forms a high proportion of the emergent and main canopy strata
of the forest. A Dipterocarp forest is richly diversified and contains
timber such as Meranti (Shorea spp.), Mersawa (Anisoptera spp), and Keruing
[Dipterocarpus spp) which are highly priced.
MANGROUE SWAMP
There are also Mangrove Swamps in the area. The largest is located
near the old prison building, north side of the island. The mangrove swamps
are named so because of the mangrove trees, which dominate these wetlands.
These trees are tolerant of the brackish water and saltier coastal conditions,
and they are usually surrounded by a watery wilderness. This area also
provides habitat and breeding ground to organisms such as crabs and jellyfish.
FLORA
Besides the wide range of flora available on the island, there are also
a variety of fauna species on Pulau Jerejak. Among the 39 animal species
here are White Bellied Sea Eagles, Monitor Lizard and Long Tailed Macaque.
THE BlRDS
The White Bellied Sea Eagle, also known, as Haliaectus Leucogaster is
black in color with a white spot underneath thus the name white bellied.
Its major resting site is at the southern tip of the island. This is an
ideal place for bird watching as this is also the perching area for many
other bird species.
THE MAMMALS
The Long-Tailed Macaque also inhibits Pulau Jerejak. They have long arms
and short legs. They are usually born with black fur, but eventually they
turn to a yellowish greenish, reddish brownish shade as they mature. Long-tailed
macaque are diurnal (active during the day) and arboreal (tree-living)
animals.
THE REPTlLES
Among the reptiles that live on the island are the monitor lizards and
mangrove snakes.
The monitor lizards are tropical reptiles. They do not divest themselves
of their tails, like some other lizards. Once lost, the tail will not
grow back. Monitor lizards swallow their prey whole. They are daytime
lizards and actively search for food.
Among other animals that live around the area are mangrove snakes. They
can usually be seen basking on brackish water environments thus the name
mangrove. They often hang over branches or banks and will drop into the
water as an escape route at the slightest provocation.
