introduces another form of wetland found in Singapore
What is a
Can one be found in Singapore?
One answer might be: 'It should be a natural beach (not man-made) surrounded
by forests and home to many kinds of animals and native plants. And the marine
life should be rich; with starfishes, sea horses, crabs and fishes all
thriving in a community amongst seaweed and sea grass beds that hug the sandy
shore. A natural beach is a wilderness area full of "living
wonders" waiting to be explored and discovered'. To a naturalist the
answer seems obvious. A natural beach is indeed one full of natural wonders.
We do have one wilderness beach that was discovered recently in Singapore - Chek Jawa. Surprise! Surprise!
Chekjawa—a natural haven comprising of six distinct
habitats - coastal forest, mangrove, sandy beach, sandflats
(lagoon), coral rubble and a tiny island (Pulau Sekudu or Frog island)—quietly tucked away at the
easternmost corner of Pulau Ubin.
Since its discovery late last year, Chek jawa has charmed and captivated all who dared ventured
out along a two-hour (by foot) dirt track.
The list of wonders in Chek Jawa
is incredible—stick insects, Flying Dragons, Oriental Pied Hornbills, junglefowls, wild boars, otters, Seashore Nutmeg Trees,
Sea Anemones, Seahorses, nudibranchs, sea cucumbers, Cow Fishes, octopuses,
stingrays, starfishes, decorator crabs, shellfishes, sea grasses, seaweed,
and sponges, etc. And the list is ever growing! During low tide, everyone
seemed to see something that others did not, especially in the sandflat at the lagoon.
let me point out something that you might not 'see'. Operating quietly
around the lagoon are two high and protective sandbars that trap and
regulate water during low tide. They are indeed the backbones of the
lagoon. Without them, the ecosystem within cannot survive (see sketch map) . Water exits through northern tidal creeks and
southern channels, only to be slowed down by the marine vegetation, which
acts as an important refuge for animals and a trap for nutrients. It is a
miniature forest below water!
Like blood, water needs aeration to he life
supporting. Water movement creates that as well as regulating temperature
and salinity in the shallow pools.

What cannot be 'seen' are also the millions of organisms in the sand and mud. These are tiny and microscopic, but highly
significant in the chemistry and well-being of the lagoon. And there are the
bigger marine animals—such as the sea horse, sea cucumber, tube anemone, sea
pen, colourful sponges, etc which you don't need
diving gear to see—just walk on the sandbars or around the 'touch- pools'
within the lagoon during low tide! During your walks, you may even be greeted
by a friendly resident wild-pig.
Chek Jawa is a unique
nature heritage richly endowed in all things natural, located right at our
own backyard. A midget in size, only about one square kilometre in area, but
it packs a big punch in terms of biodiversity and having six natural habitats
(communities) within this small area.
Chek Jawa's is rare and
has an identity and character of its own—it reveals and transforms itself
into a natural WETwonderLAND during low tide. When
the tide comes in, it is fully submerged—its secrets and treasures are again
hidden, waiting yet to be discovered another day.
Chek Jawa is an open gym
and classroom, and a perfect poet's corner for "body, mind and
spirit" all in one. Chek Jawa—a
place in the heart—yours truly.
