The Brown Pelican inhabits parts of the Caribbean and the United States Atlantic coast. They were registered as an endangered species nearly forty years ago due to a wipeout caused by a pesticide known as DDT. This toxin caused the pelicans to lay alarmingly thin-shelled eggs that would crack during the incubation process, pushing the Brown Pelican to the brink of extinction. Luckily in 2009, the U.S. Fish and Wildlife Service was able to remove the Brown Pelican from the Federal List of Endangered and Threatened Wildlife. Their population levels have reached historic highs and have put the minds of scientists at ease. They are a vital part to the success of coastal environments and we should be happy that they have made such a comeback!

The vaquita is a small and rare porpoise that is found in the gulf between California and Mexico. With less than 150 vaquita left, protective measures are being taken to save the dwindling population. Because of commercial and antisanal fishing, 40 to 80 of these adorable porpoise are killed yearly. To fix this problem, laws have been implemented to eleminate the gillnets and shrimp trawls as well as a wildlife refuge for the porpoise population.
The American peregrine falcon breeds only in North and Central America. Prior to the 1940s, there were approximately 3,875 nesting pairs of peregrines in North America. From the 1940’s through the 1960’s, however, the population of the peregrine crashed after the introduction of synthetic pesticides. By 1975, there were only 324 known nesting pairs of American peregrine falcons in the U.S.
ReplyDeleteScientists investigating the peregrine's decline found unusually high concentrations of DDT in the falcons. In 1970, the American peregrine was listed as endangered and the use of DDT was banned in Canada in 1970 and in the United States in 1972. This was the single most significant action in their recovery. Also, offspring that were held in captivity by falconers were released.
By 1998, the total known breeding population of peregrine falcons was 1,650 pairs in the United States and Canada and other recovery goals, including estimates of productivity, egg-shell thickness, and contaminants levels, had been met. The America Peregrine was delisted in 1999.

Australian Sea-lion
"Having been hunted almost to extinction, the Australian sea-lion is a protected animal. It is rare and vulnerable, and it is estimated that there are about 5000 Australian Sea-lions altogether."

Bald Eagle
ReplyDeleteDirk Kempthorne announced the removal of the bald eagle for the list of threatened and endangered species at a ceremony June 28 at the Jefferson Memorial in Washington, D.C. After nearly disappearing from most of the United States decades ago, the bald eagle is now flourishing across the nation and no longer needs the protection of the Endangered Species Act.
The bald eagle first gained federal protection in 1940, under what later became the Bald and Golden Eagle Protection Act. The eagle was later given additional protection under the Migratory Bird Treaty Act. Soon after passage of the Eagle Act, populations stabilized or increased in most areas of the country. However, the eagle population fell into steep decline in later decades, due primarily to widespread use of the pesticide DDT after World War II. DDT accumulated in eagles and caused them to lay eggs with weakened shells, decimating the eagle population across the nation. Concerns about the bald eagle resulted in its protection in 1967 under the predecessor to the current Endangered Species Act. The eagle was one of the original species protected by the ESA when it was enacted in 1973.
The legal protections given the species by these statutes, along with a crucial decision by the Environmental Protection Agency to ban the general use of DDT in 1972, provided the springboard for the Service and its partners to accelerate recovery through captive breeding programs, reintroductions, law enforcement efforts, protection of habitat around nest sites and land purchase and preservation activities. The eagle responded dramatically to these actions. From an all-time low of 417 breeding pairs in 1963, the population in the lower 48 states has grown to a high of 9,789 pairs today. Fortunately, the bald eagle has never needed the protection of the ESA in Alaska, where the population is estimated at between 50,000 and 70,000 birds.

Giant Panda
Today, the giant panda's future remains uncertain. As China's economy continues rapidly developing, this bamboo-eating member of the bear family faces a number of threats. Its forest habitat, in the mountainous areas of southwest China, is increasingly fragmented by roads and railroads. Habitat loss continues to occur outside of protected areas, while poaching remains an ever-present threat.
Great strides have been made in recent years to conserve the giant pandas. By 2005, the Chinese government had established over 50 panda reserves, protecting more than 2.5 million acres - over 45 percent of remaining giant panda habitat – protecting more than 60 percent of the population.

The boreal Toad in Colorado is on the brink of extenction. It is an endangered species and it had to wait a long time just to be put on the list. It is a toad that is mostly isolated from other ecosystems and is confined to the high altitude wet habitats. Due to the pollution that is occuring today, the toad's habitat is diminishing and it is becoming endnagered. Furthermore the toad had to wait a while to be put on the list becuase the wild-life officials refused to acknoledge at first the declining habitat of the Boreal Toad.
Polar bears are cool like guys. When the mom has her cubs shrle usually has one to two cubs at a time. The baby cub usually stays with the mom for about to and a half years then they lieave their mom. But sometimes the babies dont even make it through the first year. They usually eat seals but because the waters are getting warmer this messes with the patterns of where they are during the winter so the bears sometimes cant get enough food dor the winter. To protect them we are putting them under the endangered species act and also trying to limit the global warming problem to protect their habitat

The golden toad was described in 1966 by a scientist in Costa Rica, where at one point, the golden toad was abundant. This toad had a glossy orange appearance, and no doubt, played an important role in the environment. Since then, major climatic change due to human carelessness has pushed this species to extinction. Not a single one has been spotted since 1989.

The Dodo bird was a flightless bird found in areas around the Indian Ocean. First discovered in the early 1500's and believed to be extinct by the end of the 17th century. Their extinction is believed to be directly related to human activities as the dodo bird didn't recognize humans as a predator, making it very easy for them to be hunted. Often used as the model for extinct species because it was the first recorded extinction to be related to human activity.

The Baiji Dolphin was declared functionally extinct, that is too few breeding pairs remained, therefore they were bound for extinction. After hunting and pollution seemed to have destroyed their habititate, this species barely spent any days off the endangered species this. Because these dolphins only resided in the Yangtze river in China, they were simply destined for extinction. Only a few years ago, scientists set out on an expedition to find evidence of the baiji dolphin. After unfortunately discovering nothing, the baiji dolphin was pronounced extinct.

Tasmanian Forester Kangaroo
ReplyDeletesince the 1800's the tasmanian forester population has declined by 90% due to the hunting for its meat and loss and fragmentation of their habitat due to clearing for agricultural expansion. they are competing with other introduced herbivores and livestock for survival. disease, road deaths, climate change, and poisonous baiting are also threating their survuval. they are protected under a law of the austrailian government and most of their range is on private property allowing their population to grow.

In february 2007, for the first time in U.S., and probably global, history a fish identified as endangered has been shown to have recovered -- and in the Hudson River, which flows through one of the world's largest population centers, New York City.
The population of shortnose sturgeon, which lives in large rivers and estuaries along the Atlantic coast of North America, has increased by more than 400 percent in the Hudson River since the 1970s. However, the shortnose sturgeon is still endangered in other rivers, Bain said, and will not necessarily be removed from the endangered species list by the U.S. government.

ReplyDeleteOnce upon a time...haha just kidding!
I actually didnt know that tigers were an endangered species. They are actually considered to be critically endangered. Of the eight original subspecies of tigers, three have become extinct in the last 60 years, an average of one every 20 years.The Bali tiger became extinct in the 1930's. The Caspian tiger was forced into extinction in the 1970's. And the Javan tiger followed in the 1980's. The tiger is killed for its skin and because its body parts are used in traditional chinese medicine.

In a world not too far away, there lived a plant named Mimulus glabratus var.michiganensis. His name was a little long...so...the locals called him the Michigan Monkey Flower. Now in this world, these giants with two legs crunched away with feet unclean on Mr. MMF and his family: Mrs. MMF, MMF jr., MMF III, MMF IV, et cetera. The giants of what they were called homo sapiens aka people. These people built with the idea of recreation and residential development destroyed a lot of the habitat of Mr. MMF and his family. Mr. MMF's aquatic home were being preserved finally by the act of a little boy named Brandon Dillman. Day by day he replanted these things. And then in 1996 Mr. MMF and his family were no longer in danger of extinction. THE End.

California Condor
ReplyDeleteA resident of the Grand Canyon area and the western coastal mountains of California, the carrion-eating California condor (Gymnogyps californianus) has a lifespan of 50 years, making it one of the world's longest-living birds. Because of poaching, lead poisoning, and habitat loss, however, it's also one of the world's rarest bird species--one that was almost wiped out completely in the 1980s. With the help of conservation efforts, 332 condors are now known to exist, including 152 in the wild.

ReplyDeleteThe tree kanaroo was a population of fewer than 100 individuals in 2001. However, ecologists are working the local citizens to reduce hunting and to protect forest habitats. The tree kangaroo's population has sharply increased in population as result of the cooperation.

ReplyDeleteYEA FOR STORY TIME!!!!!!!!!!!!!!!!!!!!!!!
Once upon a time there was a mammal called a Lemur in the land of far far away Madagascar. There where taboos aginst killing these delightful creatures, but the humans destroyed their homes, and let their famalies starve in the wilderness untill they all died. So much for happily ever after.
The Sea Turtle. Sea Turtles are hunted and killed for a lot of reasons. In some countries, people think that sea turtle is a delicacy, so they kill the turtles for their meat. Some countries also use sea turtle to make boots and pretty clips for girls hair. Some people accidently kill sea turtles, for instance, when people are boating on the open ocean and they hit something. What did they hit, well, they hit a sea turtle and there is a super huge gash in its shell. Sea Turtles are still endangered, but their numbers are getting a little larger, so hopefully they will make a come back and not become extinct.

ReplyDeleteThe Vancouver Island marmot is among the world's most endangered and compelling animals—a counterpart, in rarity and cuteness, to China's giant pandas. No wonder an unlikely coalition that includes everyone from schoolchildren to a ski resort is making a last-ditch effort to save it.
For as word of its imminent demise has spread, an unlikely coalition of marmot lovers—including everyone from biologists and families to loggers and ski resort developers—has come to the animal's rescue. Kids have helped wage a successful public relations campaign replete with children's books, stuffed animals, and marmot drawings taped to parents' refrigerator doors. Businesspeople have kicked in money and land to help create a costly captive-breeding program. Motivated by a mixture of love and enlightened self-interest, the marmot's champions are making a desperate effort to bring it back from the edge of extinction—an effort made all the more challenging by the appetite of other island animals. Just when the marmot's prospects looked most promising, predators took a big bite out of the wild population. Now the next move for the marmot protectors is one fraught with controversy.
The marmot's star qualities, it's that it isn't the type to give up without a fight—after all, it has thousands of years of survival under its belt already, much of it through dramatic geologic and climatic change. When scientists began intensely studying the animal in the 1970s, they discovered Marmota vancouverensis—with its unique chestnut and white coloring—to be distinct from the 14 other nonthreatened marmot species that live throughout North America, Europe, and Asia. It was separated from its closest cousins—the hoary and Olympic marmots—when an ice bridge that linked Vancouver Island with Canada's mainland melted about 10,000 years ago. Over time this marmot has survived periods of cold so intense that much of the land was encased in ice, driving other island animals, such as mountain goats, to extinction.
But while it persevered, the Vancouver Island marmot never flourished, and its eventual scarcity—a mere 68 individuals were recorded between 1896 and 1972—prompted the Canadian government to declare it an endangered species in 1978. Then things started to look up. Between 1981 and 1984 annual counts nearly doubled, to about 235 animals.
The reason for the baby boom was, at first, a mystery. After all, the marmots' surroundings had undergone radical change in recent decades, and not for the better. Chainsaws had opened gaping holes in the once-pristine conifer canopy, and logging roads had zigzagged up and down the mountains as far as the eye could see…….

Hunting quotas and egg collection programs cracked the gator decline in the southeastern United States. Landowners collect eggs, when alligators are most vulnerable to predators, sell some of them to gator ranchers, and return the rest of the hatch to the wetlands.

Cougars, not women who pray on younger men, but an animal from the cat family is losing numbers. Cougars having been living in mountainous areas for years and yet we as humans are bring them down. cougar's homes are being destoryed all the time with the building of homes and the over hunting of this population. when a female cougar is killed it's cub dies with it, whether it was hunted or because it can't survive due to the loss of it's mother. also the endangeredment of the white-tailed deer is having a ripple effect on cougars. this is one of their primary food sources and it to is being over hunted.

Florida manatee
ReplyDeletehttp://www.esasuccess.org/reports/
The Florida manatee (Trichechus manatuslatirotris latirostris) lives in freshwater, brackish and marine environments and inhabits shallow coastal waters, estuaries, bays, rivers, and lakes [1]. Florida manatees occur in waters of the southeastern United States, primarily in Florida and southeastern Georgia, but individuals can range as far north as Rhode Island and probably as far west as Texas [2]. During winter, cold water temperatures keep the population concentrated at warm water sites in peninsular Florida [2].
Collisions with boats represent the greatest current threat to Florida manatees but water control structures also account for significant mortality. Habitat loss caused by residential and commercial development also remains a problem and the loss of warm water refuges could pose a significant threat [2].

ReplyDeleteThe black footed farrot was being over hunted and was also losing its home because of building but then 1967 they were put on the endangered species list. They where so close to extinction but eventually because of the endangered species act there population is slowly coming back but its still a work in progress but there has been much improvement.
