The Indian Paintbrush is one of 13 plant species endemic to the Island of San Clemente, California. A survey of the entire island conducted in 1979 found less than 500 plants. The decrease was mainly due to grazing and trampling by feral goats and pigs. After actions to protect the species were taken, in 1997, another survey was conducted. This survey showed the population of this plant increased greatly, there were about 3,500.

Golden Toad
ReplyDeleteFrom 1966 to 1983, 1500 adult toads were found. By '88, only 10 or 11 were seen. The spring of '87 was very warm and evaporated the temporary breeding pools (before the tadpoles could mature) which were being studied by an American biologist. in '88, only one male frog was found and seven males and two females at another site. In 1989, only one male was found. No golden toad has been found since. The toads were being kept at the Monteverde Cloud Forest Preserve.

The Hawaiian Goose was listed as an endangered species in 1967. They have increased their population from 400 birds in 1980 to 1,275 in 2003. Because of excessive hunting they almost came close to extinction. In 1951 there were only 30 birds remaining. Mongoose, cats, dogs, and rats were the main threats to this population. Conservation work was being done and that helped to increase the population of these anmials and then they were released back into the wild. But then in the 1970's and early 1980's the releasing of the birds was stopped because they were dependent on releases of captive-bred stock to keep their numbers in the wild up. But ever since the stoppage of these birds the numbers have recovered because of the trapping of predators and supplementing the population in the wild.
ReplyDeleteThe red wolf was once found throughout forested regions from southern New England to the Gulf Coast. By 1920, the red wolf was considered extirpated from the Southern Atlantic States. By 1970 the population had declined to less than 100 wolves and was confined to a small area of coastal Texas and Louisiana. These declines were the result of aggressive predator control programs and the loss of forest habitat.
ReplyDeleteEarly recovery attempts were largely unsuccessful and as the last Red-wolf population continued to decline, remaining individuals began mating with coyotes. As a result of such hybridizations the number of genetically pure Red wolves decreased and further contributed to the species decline. In a final attempt to save the species, 17 genetically pure red wolves were eventually captured for captive breeding efforts.
The red wolf captive breeding program established at the Point Defiance Zoo and Aquarium in Tacoma, Washington was able to successfully breed 14 of the original wolves and the first reintroduction occurred in 1978 on Bulls Island off the coast of South Carolina. In 1980, the last remaining wild Red wolves were brought into captivity and the species was declared extinct in the wild. The captive breeding program continued, however, and has now expanded to include 38 zoos and nature centers in 23 states. In 1988 the first wild-born litter since reintroductions began was found at Alligator River National Wildlife Refuge, North Carolina.
Red wolves have now been re-introduced into areas in North and South Carolina, Great Smokey National Park in Tennessee, and on three islands off the Atlantic and Gulf Coasts. Introductions to the coastal islands have acted as a stepping stone between captivity and the wild; although the islands are too small to support wolf populations, they provide an opportunity for the wolves to breed and exist in the wild and to produce animals for future mainland reintroductions.
In 2003, approximately 100 Red wolves existed in the wild with another 157 held in captive breeding facilities (this includes two island propagation programs). In 2004, 11 of 22 packs had created dens.

Once upon a time....Asian Elephants were all over, living their lives as normal animals would. One day, their lives started to take a turn for the worse. People started moving into their territories and turned their homes into factories and other needless items. The first of the elephants started to die. After that, the people started to get hungry...with greed. They started killing elephants for food. They even killed them for their ivory and many other valuable parts. Their greed got the best of them until one day, a little girl poped out of nowhere and begged the people to stop. She told them to look around them and see what they have caused...to look at the pain and suffering they were giving the elephants. When they looked up and saw, they were shocked. The people got together and found a way to stop what they were doing and decide to help the elephants as a way of paying back for their greedful deeds. To this day, the Asian Elephant is still alive, but in very small numbers. The people are still there, making sure that no more harm comes to the elephants...all because of the words of a little girl.

Red Wolf
ReplyDeleteHunting and habitat loss reduced the red wolf to fewer than 100 individuals by 1970 and by 1980 the species was considered extinct in the wild. In 2003, approximately 100 red wolves in 22 packs existed in the wild with another 157 wolves held in captive breeding facilities.
The Guadalupe fur seal was overhunted in the 1880's. The species was thought to be extinct until a male was found on San Nicholas Island, California in 1949. 14 seals were found there and were put under protection and and have now recolonized the California area.
ReplyDeleteBald Eagle
ReplyDeleteThe bald eagle declined throughout the Lower 48 states due to habitat loss and DDT application. The banning of DDT, increased habitat protection, and aggressive captive breeding and translocation programs caused the number of bald eagle pairs in the Lower 48 to soar from 416 in 1963 to approximately 9,789 in the latest census between 2004-2006.

The tree kangaroo population had decreased because of hunters. They couldn't reproduce as fast as humans were killing them. After noticing that the kangaroos were dying off there was a law passed to stop the hunting of kangaroos. The kangaroo population increased after the law was passed. The hunters no longer kill or hunt kangaroo for the skins and other things. Kayla sanderson prd 4
ReplyDeleteBald Eagles
ReplyDeleteAs of June 28th 2007, the bald eagle is no longer on the endangered species list. After being placed on the list around 1940, populations have stabalized over time. This was due to federal protection of the animal against hunting as well as placing them in wildlife reserves. A ceremony was held at the Jefferson memorial in Washington DC to celebrate the removal of this symbolic bird from the endangered species list. Although it has been removed from the list, the bald eagle will still be protected under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act.

The grey wolf (Canis lupus) was placed on the endangered list in 1974 after the animals were almost eliminated in many U.S. states. They have now been removed thanks to conservation efforts its numbers now reach some 4,000 in the Great Lakes region, which includes Michigan, Minnesota and Wisconsin, and there are more than 1,300 in the Rocky Mountain states of Idaho and Montana. There are also between 8,000 and 11,000 grey wolves in Alaska. In all these states wolves can now be hunted again according to strict regulations.

One endangered species is the southwestern willow flycatcher. It is a type of bird that has become endangered due to flooding and human development. However, people are trying to help and are putting in place a plan that targets farmers and private landowners because most of the bird's habitat is on privately owned land. This plan will focus available conservation dollars and wildlife expertise for their recovery.
ReplyDeleteThis is an adorable bat...
ReplyDeleteSAVE THE ALADABRA FLYING FOX
One of the only four mammals found on Aldabra Atoll in the Seychelles. This animal is protected and its habitat is no longer allowed to be touched by human hands. Without this protection they fear this animal could become extinct.
Since they have changed the regulations on this little bats habitat the bat has been doing considerably well.
The bald eagle became endangered when habitats were was lost when virgin forests were cleared
ReplyDeleteAnimals that eagles eat we're killed.
Eagles were shot because they were thought to threaten livestock
DDT, made eggs too thin and caused reproduction rates to decline.
They recovered only when we banned DDT, banned killing them, improved water quality And guarded their eggs
The bald eagle finally soared off the endangered species list through a lot of help to recovery.

The polar bear has always been a material, spiritual, and cultural life of Arctic indigenous peoples, and polar bears remain important in their cultures. The polar bear has become an endangered species mainly due part to environmental changes of the ice melting earlier each year. they have a predicted path of extiction in this century about half way through it.
ReplyDeletein order to save the endangered species we must kill them??

The North Carolina Flying Squirrel:
ReplyDeletethis squirrel is a relict of the last ice age. It cannot actually fly, but it uses extra skin that stretches the length of its body to somewhat glide. It is found on high mountain peaks in western carolina. Threats of the species include urbanization, exotic pests introduced, pollution, and limited range of living.
The Northern Right Whale was given its name in the nineteenth century because it was then deemed "The Right Whale to Kill". Northern Right Whales are slow swimmers, floated when dead, and produced plenty of baleen and oil, making them the perfect prey for whale hunters. Northern Right Whales are baleen whales, and though they are now protected from being killed by whale hunters they are now being affected by climate change because that affects krill, the fish they feed on. They are also relatively slow to mate, staying with their mothers for two to three years and reaching sexual maturity at the age of ten. Typical females will give birth every two to seven years.
ReplyDeleteThe gorillas are huge animals. The male gorilla grows to about six feet high, and weighs up to six hundred pounds. The female gorilla grows to about five feet high, and weighs up to two hundred pounds. The gorilla is put on the endangered species list due to the projected population declining to at the highest 50% due to a decline in area of occupancy.
ReplyDeleteThe bald eagle was placed on the endangered species list on July 4, 1976. At this time there were around 416 pairs of bald eagles and had almost disappeared from the entire country. In 2006 there population had grown to over 9000 pairs. Now they are found in every state except Hawaii. They can be found throughout the wild and in many zoos that continue to help protect them and let their population grow.
ReplyDeletered wolves - the reason for their endagered species status is due to over hunting because intensive predator control programs set back in the 1960s, and due to loss of habitat.
ReplyDeleteThey recently have just started to recover, the few hundred remaining left were captured and kept in a controlled area where they can eventually repopulate and thrive once more.

The Hawaiian Monk Seal has an estimated population of 1,100 at a decreasing rate of 4% each year. The reason for their endangerement is due to entanglement, predation and malnutrition. The Marine Mammal Center has worked closely with government agencies and nonprofit organizations in Hawaii for the past decade to to provide medical assistance to monk seals.
ReplyDeleteThe Yangtze River Dolphin became endangered in the 1970s, when there was only about 500 left. Twenty years earlier there was over 5,000. It was declared functionally extinct in 2006, when researchers couldn't find any left in the wild. The main causes of their decline are entanglement in fishing gear, collisions with ships and boats, habitat loss, pollution, and being hunted for their flesh and skin. There have been a few sightings since they were declared functionally extinct, but if there is only a few dolphins left it can't save their species from true extinction
ReplyDeleteBizant River Sharks
ReplyDeleteThe Bizant River Shark is called many names. It's scientific name is the Glyphis glyphis. Little is known about it becuase of it's rarity. There are very vulnerable to extinction because of their very specific habitat, low productive rate, and of course, human inteference. They die very often from line fishing, gill netting, and habitat destruction. They are frequently confused with Bull Sharks due to similarities in habitat, since Bull Sharks are commonly known as THE river shark, without clarification that there are other river sharks. This causes people to kill the Glyphis glyphis out of hate for the Bull Shark, which has been known to openly attack people. If we continue to harm the Glyphis glyphis, they will soon go extinct, and we will never learn the mysteries behind this other river shark.

RED
ReplyDeleteThe red panda is dwarfed by the black-and-white giant that shares its name. These pandas typically grow to the size of a house cat, though their big, bushy tails add an additional 18 inches (46 centimeters). Their avereage lifespan is 8 years. The red panda has given scientists taxonomic fits. It has been classified as a relative of the giant panda, and also of the raccoon, with which it shares a ringed tail. Currently, red pandas are considered members of their own unique family—the Ailuridae. Red pandas are endangered, victims of deforestation. Their natural space is shrinking as more and more forests are destroyed by logging and the spread of agriculture. Red pandas are so important, they are the symbol of the International Tea Festival in Darjeeling, these kind of pandas are threatened by hunting (both for fur and for skin), deforestation (it cuts sources of food and places of living).

southern sea otters was almost to extinction because of its fur but in 1911 they passed a National fur treaty to protect the remaining otters and then in 1977 they were placed on the endangered species list. They keep declining but in 1996 their population incresed and they have been slow incresing since then.

the cape seahorse, native to south africa, is only found in a few estuaries. there are laws protecting it but the development or the area and the pollution are causing them to still die. in a few short years the will be completely extinct.
ReplyDeleteonce upon a time there were Tree Kangaroos living happy and free. but one day hunters decieded to kill them. the kangaroos couldnt make other kangaroo babies as fast as they were being killed. the tree fairy saw this and decided to pass a law saying that it is not right to kill these poor animals!

ReplyDeleteThe Alexander Archipelago wolf is an island wolf. These distinct wolves roam the islands and coastal mainland in the Alexander Archipelago, a network of more than 1,000 islands, glaciated peaks, and deep river valleys in remote southeast Alaska. This region is also home to the Tongass National Forest, the largest national forest in North America, with some of the largest remaining stands of old-growth, temperate rainforest in the world. But the wolves and their rainforest home are under continued threats from industrial logging, road building, overharvest from hunting, and large-scale habitat loss as the U.S. Forest Service continues to plan big timber sales in key wolf habitats.
The Center has been working to save the Alexander Archipelago wolf since 1996, when we and allies first petitioned to protect the wolf under the Endangered Species Act. After we filed suit against the U.S. Fish and Wildlife Service for failing to protect the wolf under the Endangered Species Act. Since then, officials have continued to deny the wolf Endangered Species Act safeguards, relying instead on the inadequate general protections bestowed under broader national forest regulations — so in 2011, with allies, we petitioned again to protect the wolf. In December 2009, we filed suit to save roadless areas on the Tongass National Forest, which make up 80 percent of the wolf’s habitat.
The Archipelago Alexander wolf needs all the help it can get. Over half of the old-growth forests that the wolves rely on for hunting, denning and raising pups are now gone. With the new Tongass forest plan, another 30 percent of the remaining old-growth forests in southeast Alaska could be gone within the next 20 years. More people live on islands with wolves, increasing legal hunting and trapping of wolves to unsustainable levels. Because of a number of severe winters, and a lack of old-growth forests for protection, the wolves’ primary food source, the Sitka black-tailed deer, are also in decline. The time to save to the Alexander Archipelago wolf is now.
Florida Panther
ReplyDeleteHunting and habitat loss reduced the Florida panther to a single population of 30-50 adults. By 2003, the number of known panthers increased to 87 and the panthers began to range over a larger area.

Giant Chinese pandas unfortunately are on the list of endangered species. One way to combat their distinction was the idea of cloning. This weighed heavily as a potential solution at one point because of the Dolly the Sheep. As this plan was thought out in long term, the government realized that this just might hold the problem off a little longer but not really solve. The real problem is that they were killing the habitat of the pandas so as long as they continue to do so the pandas will eventually go extinct.

ReplyDeleteThe Great Lakes piping plover once prospered throughout the central and eastern United States as their numbers fluctuated between 500-700 pairs during the 1800s. Because of hunting, egg collecting, furthering of public recreation, and general shoreline development the plovers' numbers decreased to a pitiful 19 pairs in 1985. Those 19 pairs were all concentrated in the state of Michigan. "Luckily", they were put on the endangered species list and aggressive management programs were put in place to monitor their breeding and prevent any predators or land development form killing the rest off (1993). Since then, they have recovered well and may soon be on the way to glory as in ye days of old.

During the late 19th century american buffalo were hunted nearly to extinction. The main or primary reason for the bison's near-demise was commercial market hunting. Bison skins were used for clothing such as robes, rugs and, for industrial machine belts. The current American bison population has been growing rapidly, and is estimated at 220,000 compared to an estimated 60 to 100 million in the mid-19th century.

The blue hyacinth macaw is a very pretty big bird with long feathers hanging from its tail.Unfortunately these beutiful birds live in third world countries and are sold for a profit for its long beautiful feathers or sold as pets. We can help these beutiful parlant birds by refusing of illegal trade of pets and if you own one help them keep this specie longer by giving it to an organization that protects macaws and will help reproduce the population of macaws.
ReplyDeleteThe African Skimmer is a skimmer that lives in Senegal to northern Congo River and southern Nile Valley, southern Tanzania to the Zambezi Valley, and then to Natal and Angola.
ReplyDeleteThey have very long wings. The back, hind neck, and crown are black. The forehead and rest of the body is white, with a bright, long, orange beak that ends with a yellow tip. Their short forked tail is white, and their legs are bright red. The average size is about 15 inches(38 centimeters) long. Their voice is a sharp "kip-kip". Their bill structure is unique. The lower mandible is much longer than the upper mandible, and flattened sideways like scissor blades.
Most seals are at home in frigid waters, but the Hawaiian monk seal is a rare tropical exception.
ReplyDeleteHawaiian monk seals live in the remote Northwestern Hawaiian Islands. These small islands and atolls are either uninhabited or little-used by humans. They are also surrounded with teeming coral reefs, which serve as great foraging grounds for skilled seals to swim and dive for fish, spiny lobsters, octopuses, and eels. Monk seals spend most of their time at sea, but come ashore to rest on beaches and even utilize fringe vegetation as shelter from storms.
The monk seal is named for its folds of skin that somewhat resemble a monk's cowl, and because it is usually seen alone or in small groups. Hawaiians call the seal `Ilio holo I ka uaua, which means, "dog that runs in rough water."
Mother monk seals are dedicated and remain with their pups constantly for the first five or six weeks of their lives. They don't eat during this challenging time and may lose hundreds of pounds.
Like the other species of warm-water monk seals, the Mediterranean and Caribbean monk seals, the Hawaiian monk seal has a tenuous grasp on survival. The Caribbean monk seal, in fact, is believed to have been extinct since the 1970s. Perhaps 300 to 600 Mediterranean monk seals and about 1,300 to 1,400 Hawaiian monk seals survive.
Humans have moved into many of the desirable coastal habitats that these animals once frequented, so open coastline is at a premium. Monk seals have also been victims of fisheries, though they are usually accidental bycatch and not a targeted species. Sharks also prey on these seals, and males sometimes kill females of their own species in group attacks called "mobbing."
Today, Hawaiian monk seals are endangered and, although many protection efforts are in place, their numbers are believed to have fallen more than ten percent per year since 1989.
