Dear Students of Chong boonites

A TOUR TO CHEK JAWA

Our school is going to have a tour at Chek Jawa. The beauty of Chek Jawa is that several different ecosystems can be seen in one small area. These ecosystems and the plants and animals found there are no longer common in Singapore. They are also fast disappearing elsewhere in the world.The hill overlooking Chek Jawa is covered with trees and plants that shelter and feed a variety of animals.

The mangroves of Chek Jawa have many interesting plants and animals. Mangrove trees have unusual shapes and properties as they are adapted to being covered in seawater at high tide and to grow in soft mud. The new boardwalk into the mangroves bring you close to these trees as well to the wonderful wildlife. Fiddler crabs and mudskippers are the highlight of a visit to the mangroves.

The coral rubble area near the front beacon is probably the richest part of Chek Jawa and also the most fragile. Rarely exposed, even at low tide, this area shelters delicate sea creatures that prefer to be submerged most of the time. These include sponges in bewildering shapes and colours, delicate fan worms and even living corals! Octopuses, seahorses, nudibranchs and colourful flatworms are some of the other amazing residents of this special part of Chek Jawa.

Please come to Chek Jawa to experience Singapore wild marine life. You will enjoy this trip and bring back lots of knowledge.


Yours faithfully

Terrorism

I think that terrorism in Singapore is not much a threat because our goverment is vigilant and will not let any signs of terrorism get into Singapore.Athough the goverment is watching over us,we must be on a look out.If we spot any suspicious items or people we must immdiately notice the police.

Terrorism affects me lightly as i have never met a terrorist and do not wish to meet one,terrorist only comes once in a blue moon. I believe that the police by now should had exterminate all signs of terrorism but there is surely something i could do to counter terrorist.I am not afraid of terrorism unless a terrorist is pointing a gun at my head or threatening to blow up himself together with me.I will try to attack the terrorist from the back if i see one in the public.

I think the punishment for terrorist should be very harsh,terrorist do crazy things and cannot control themself so imagine what will they do again if we release them.So hanging them to death of punishing them for life in prisonment is not a bad idea. If a terrorist really change then we should give him a second chance.We can help by staying vigilant and help to fight the terrorist if you see one on the road

BROWN BEARS

After doing researh on the brown bear it made me understand more about them and urges me more to open a animal santuary in America saving those poor little creatures from extinction. We should save the earth and wildlife from pollution as we only have one earth and we share it animals not only ourself so we must be considerate to those bears.

So no more killing of bears. If we continue doing that we will devastate their population and even cause them to be extinct.All animals have the right to live so we have to respect those bears. Remind yourself to donate more to the Singapore zoo and any animals organisations. Donate as much as possible. Bear live on the earth too so they have everyright to live. We should not take away their freedom by cutting down more trees and destrution of their habitats.So we must save bears.

BROWN BEARS

Human is a major threat to brown bears,as our population grows, we encroach on bear habitat, driving them further into ever shrinking wilderness. Humans have become the single biggest threat to all wild animals.

Bears are the largest land based carnivores on the planet. However, due to their varied diet they are better characterized as omnivores. Typically, a grizzly bear's diet in the Columbia Mountains consists of less than 15% meat. The remainder is roots, herbs, berries, and insects.

Locally, grizzlies make extensive use of avalanche chutes in search of foods such as sedges, grasses, cow parsnip and various bulb-producing flowers. Aided by their long front claws and massive shoulder muscles, they rototill beds of glacier lilies and spring beauty to harvest the nutritious bulbs, and they excavate fat and protein-rich Columbian ground squirrels from their burrows. In mid-summer, grizzlies often move to huckleberry patches in burned over forests to fatten on a diet rich in carbohydrates to prepare for winter.Killing a grizzly bear in the lower 48 States in america is both a federal and state offense that can bring criminal and civil penalties of up to $50,000 and a year in jail.

Now many organisations are helping brown bears and will never let them be extinct.We can help too by donating money to organisations that help bears. We can play a part to ensure the future of the bears. We human created all these problems we must solve it too.

BROWN BEAR

Most people think that forest fire do more harm than more benefit to the brown bears but think again.Actually forest fire do benefit the brown bears
Fires that occur within remote wilderness portions of the grizzly bear recovery ecosystems, generally created a natural mosaic pattern of burned and unburned vegetation. Grizzly bears will benefit from increased diversity in the landscape and increased abundance of grizzly bear foods over time.

Survival of mammals in forest fire areas is in the upper 90% range. By creating many different food sources, these fires are beneficial to the grizzly bears. First of all, by burning away dense timber and smaller plants, it creates nutrients for future successional plants. In Montana , grizzly bear diets include huckleberries, which are successional plants. The fires also open up the canopy of trees in wilderness areas, allowing sunlight to filter in for smaller plants to be established. Some of these plants are also food sources for grizzly bears.



Grizzly bears often stay only a few hundred yards from a burning fire line. It has been observed that in these situations, they have appeared calm and unafraid of the fires. By staying close to the fire lines, bears are able to capture small prey running out of the burning forests. When the fires have subsided, grizzly bears re-enter the burn area, and obtain food sources from uncovered caches of pine nuts, homeless, small rodents, and those "barbecued" animals that were trapped by the fires. The overall long-term impact of fire is that it increases the diversity of habitats and maintains the resililience and vigor of ecosystems which is beneficial to grizzly bears

After the musk ox, the grizzly has the second slowest reproduction rate of all North American mammals, making it harder for it to rebound from threats to its survival. Females do not reach breeding maturity until they are 4 to 9 years old and generally give birth to two cubs every 3 years. On occasion, one or three cubs may be born to a female, but two is the more common number.So you see,we must stop killing brown bears or not we will never see them again...

BROWN BEARS

Brown bears are usually solitary animals with the exception of females and their cubs but at times they do congregate.Dramatic gatherings of grizzly bears can be seen at prime Alaskan fishing spots when the salmon run upstream for summer spawning. In this season, dozens of bears may gather to feast on the fish, craving fats that will sustain them through the long winter ahead.

Brown bears dig dens for winter hibernation, often holing up in a suitable-looking hillside. Females give birth during this winter rest and their offspring are often twins.Grizzly bears are powerful,top of the food chain. Nearly half of all brown bear cubs born are likely to die before they’re a year old. Some die of disease, and others die of starvation. Predators such as wolves, adult male bears—even a cub’s own father—are threats, especially to cubs that are separated from their mothers. But mother brown bears are fiercely protective, so many cubs do survive. Giving birth to 1 to 3 cubs and being hunted down by poachers i can see that the brown bears population is droping.

Some of the brown bears neighbours Elk, Moose, Cougars, Gray Wolves, Black Bear, Coyote, Dall’s Sheep.

Although grizzlies will, for the most part, avoid contact with humans, they are sometimes unpredictable and should be given plenty of room; every year, bears maul or kill humans. They move with a slow shambling walk, the low-slung head swinging from side to side. They can move very quickly, however, and even horses find it difficult to evade a rushing grizzly.So we must beware of them.We must educate the people in America let them know more about this mammals so that both bears and human can live peacefully together

BROWN BEAR

Brown bears live in almost all kinds of habitat from dense forests, to subalpine meadows and arctic tundra. In North America, grizzly bears are found in western Canada, Alaska, Wyoming, Montana, Idaho, and Washington. Historically, they could be found from Alaska to Mexico, California to Ohio. The grizzly bear was once common on the Great Plains. However, human encroachment has forced the remaining brown bear populations to move to rugged mountains and remote forests that are undisturbed by humans.


Bears live solitary lives except during breeding, cub rearing, and in areas with a super-abundant food supply such as salmon streams. Grizzly bears hibernate during the winter for 5-8 months, and usually dig their dens on north-facing slopes to ensure good snow cover.

Grizzly bears need to eat a lot in the summer and fall in order to build up sufficient fat reserves for surviving the denning period. This is particularly true for pregnant females who give birth to one pound cubs and then nurse them to about 20pounds before emerging from the den in April -May.

The females give birth from 1 to 3 cubs,the cubs will remain with their mother from 2to 4 years.

In 1975, The U.S. Fish and Wildlife Service listed the grizzly bear as a threatened species in the Lower 48 states, under the *Endangered Species Act. In Alaska, where there are estimated to be over 30,000 grizzly bears, they are classified as a game animal with regionally established regulations. The Yellowstone population of grizzly bears was declared recovered and removed from the 'Threatened' species list in April of 2007.Celebration
