In September 2016 , after almost 50 long time of managed fostering and conservation efforts , the giant panda was upgrade from " endangered " to " vulnerable " on theIUCN cherry leaning . Now , there are between1800 and 2050giant pandas in the world , and the number is increase .

It ’s not the first time a species has been dragged back from the threshold . Here are eight other brute that have made a rejoinder — with help from preservation laws and consecrate scientists .

1. American Alligator

American alligator , the turgid reptile in the U.S. , are foundacross in the Southeastin wetland , river , and evengolf grade .   But once upon a time , the alligator was on the verge of extermination , thanks to the popularity of its skin as fabric for horseshoe , jackets , and bags .

In 1967 , the alligator was listed as " endangered " under the Endangered Species Preservation Act ( theprecursorto the Endangered Species Act of 1973 ) . Twenty geezerhood after , their status was upgrade to " threatened " [ PDF ] , which continue current . Today , about 5 million alligators vagabond the U.S. from Texas to Florida to North Carolina .

2. Southern White Rhino

Whiterhinocerosesare the second large res publica mammal ( afterelephants ) and are classified into northern and southerly subspecies . deplorably , there areonly two northerly blanched rhinosleft alive , espouse intensive poaching for their horns . But southern white rhinos are faring better .

Europeans settlers and boastful biz Orion about pass over out the southern white rhino population in the late 19th one C . Conservationists then found a chemical group of fewer than 100 animals in South Africa and vigorously protected them , and southern white rhinos populations have rebound . The World Wildlife Fundestimatesthere are between 19,600 and 21,000 individuals now living in South Africa , Namibia , Zimbabwe , and Kenya , and the IUCN Red List classifies them as " near - threatened . "

3. Grizzly Bear

The grizzly bear was once on the sceptre of disappearing from the lower 48 United States Department of State thanks to habitat passing . By 1975 , when grizzly bear wereprotectedunder the Endangered Species Act , only 136 of the bears roamed Montana , Idaho , and Wyoming . Now , there are around1850 grizzliesacross six ecosystems in the upper Rockies and Pacific Northwest . A recent five - year subject by the U.S. Fish and Wildlife Service concluded that , while Ursus horribilis continue to recover , they should remain lean as " threatened " [ PDF ] .

4. Peregrine Falcon

The fastest hoot on the planet , peregrine falcons could n’t outfly the effects of DDT . The wide used pesticide made their eggs ' shells to reduce for minor to survive . mobile populations plump by the 1960s , and the falcon was first listed as " threaten " in 1970 . Conservationcampaignsagainst the pesticides , habitat loss , and other threats brought the razzing back from the brink of extinction . The recovery led to their delist from the Endangered Species List in 1999 [ PDF ] .

5. Channel Island Foxes

The island fox , which is endemic to California ’s Channel Islands , suffer a 90 per centum population reduction in the nineties . Distemper outbreaks and predation by birds and feral pigs abridge the foxes on five of the six Channel Islands from 6000 tofewer than 1500by 2002 . Thanks to captive breeding and reintroduction efforts , the fox population is increase and numbers about4000 mature individualstoday . In 2016 , three race — the San Miguel , Santa Rosa , and Santa Cruz island Charles James Fox — were polish off from the Endangered Species List , and the Santa Catalina island slyboots was promote from " peril " to " threatened " [ PDF ] .

6. Gray Whale

Centuries of whaling boil down the populations of grayish hulk to just a fraction of their historical number and Pacific Ocean habitat range of mountains . commence in the 1930s , Pacific Rim nation impose cadence to conserve the remaining gray whales , and in the early 1970s , the U.S. government protected them under the Endangered Species Act and theMarine Mammal Protection Act . The long - migrating cetaceans in theEastern North Pacificand Arctic seas recovered sufficiently to be removed from the Endangered Species List in 1994 , but a universe in the Western North Pacific remains endangered .

7. Lesser Long-Nosed Bat

This petite , cinnamon - colored bat isadaptedto life history in the desert . They rest in the cave and old mines scattered across southerly Arizona and New Mexico , and sip nectar from saguaro cactus and agave blossoms . Habitat fragmentation and the destruction of their roosting sites reduce their numbers and prompted Congress to heel them as " endangered " in 1988 [ PDF ] . Because populations do inhabit more than 40 per centum of Mexico , and less long - nosed cricket bat in the U.S. have been capable to recover from the season - to - season fluctuation in their number , they were delist in 2018 .

8. Wood Stork

A large American wading bird , the woods stork ’s populationdroppedby 90 percent between the thirties and 1980s due to commercial-grade development and water drainage in South Florida . The storks shoot down on the endanger species inclination in 1984 . Thanks to cooperation between governments and conservation group in restoring wetlands in the southerly U.S. , the wood stork universe is back up around16,000 breeding adult , and its position wasupgradedto " threatened " in 2014 .
