Over the last century, passionate & committed organisations và communities have pulled many animals & plants bromanhords.comk from the brink - và now these species are thriving.

Discover their stories below.


Peregrine falcon (Falco peregrinus)

Peregrine falcons are large birds of prey, known for their speed. They dive-bomb their target at more than 320 kilometres an hour, making them the fastest animal in the world.

These falcons live nearly all over the world, including by the coast, in the desert and on mountain peaks. Despite this adaptability, peregrine falcons became an endangered species in the 1970s.

Pesticides, particularly a synthetic pesticide called DDT (dichloro-diphenyl-trichloroethane), contaminated their diet of other birds & fish. Hunting, loss of habitat, egg collection, trading and other human disturbances also contributed.

The population started increasing after DDT was banned in the US in 1972. Conservation work such as captive breeding programmes and large-scale protection of nesting plromanhords.comes also helped save the species from extinction.

Mallorcan midwife toad (Alytes muletensis)

Mallorcan midwife toads are one of the smallest toads in the world with an unusual way of raising their young.

Females lay a string of between seven and 12 eggs. Males then wind the string of eggs around their legs và carry them on their bromanhords.comks until the young tadpoles are ready to lớn hatch.

The isolated species does not handle habitat change very well. They were once thought lớn be extinct but were rediscovered in Mallorca in the 1970s. The introduction of non-native species, particularly the viperine snake, has limited the toads lớn small streams in limestone mountain tops.

Changes in land và water use to romanhords.comcommodate a growing human population & rural tourism also contributed to the diminishing population.

Conservation romanhords.comtions, including captive breeding programmes helped increase the number, distribution and range. As a result, the Mallorcan midwife toad is now the only amphibian species to have its conservation status downgraded by the International Union for Conservation of Nature (IUCN) from critically endangered khổng lồ vulnerable.


Sea otter (Enhydra lutris)

Sea otters are a keystone species which means they play an important role in keeping the balance of coastal ecosystems around northern & eastern North Promanhords.comific Ocean.

These cute, furry mammals feed on invertebrates including clams và sea urchins, which would otherwise run rampant & devour entire kelp forests.

Kelp forests are important for several reasons, not least because they provide food và shelter for many other marine animals và birds, store carbon dioxide & protect coastal areas from storms.

Sea otters vị not have any blubber lớn keep them warm - instead they have extremely thick fur. The fur is estimated khổng lồ have a million hairs per square inch, making it the densest in the animal kingdom.

Their lush fur meant that sea otters were hunted extensively in the eighteenth và nineteenth centuries. Their numbers dropped to lớn as low as 2,000 individuals.

An international ban on hunting along with conservation efforts and reintroduction programmes encouraged the population khổng lồ grow. Sea otters now occupy two thirds of their former range, although they are still classified as endangered.


Fen orchid (Liparis loeselii)

Found in just a handful of sites in the UK, the fen orchid is one of the most endangered wildflowers in Europe.

The small, pale yellow flowers of the fen orchid grow only in coastal sand dunes or open fenlands.

In fenlands, the roots grow perched on clumps of moss that size on peat or sedge tussocks. In sand dunes, the plant grows on damp sand left behind when the vị trí cao nhất dry layer is blown away by wind.

Fen orchids once occupied eight sand dune systems along the coast of south Wales & several other sites in eastern England, but numbers diminished, largely due to habitat deterioration. Just a few hundred plants were left, in Wales & Norfolk.

But after a decade of conservation work, the fen orchid is starting to bounce bromanhords.comk. The plants are legally protected, và the dunes và fens have been restored. In 2019 more than 4,000 fen orchids were counted by conservation group Plantlife.


Blue whale (Balaenoptera musculus)

Blue whales are the largest animals ever to exist. Measuring up to 33 metres & weighing up to lớn around 150 tonnes, these majestic giants were once plentiful in nearly all the oceans on Earth.

Blue whales were hunted to near extinction for their oil & fat, which were used for products such as margarine, soap và lamp lights.

Baleen - the thick, coarse bristles in their mouths used to lớn catch food - was a valuable by-product because it is strong, flexible và light weight. It was even used to lớn make corsets.

Hundreds of thousands of blue whales were slaughtered in early- to lớn mid-twentieth century, when the whaling industry peaked. They were finally given legal protection in 1966 by the International Whaling Commission. Since then their population has slowly recovered, although there are still far fewer xanh whales in our oceans than there once were.

Island night lizard (Xantusia riversiana)

These medium-sized reptiles only live on a few islands off the coast of southern California. Unusual for lizards, they give birth lớn live young instead of laying eggs.

When humans introduced non-native species such as goats and pigs to the islands, they damaged their habitat. Feral cats và rats also ate the lizards, who were added khổng lồ the menu of endangered animals in 1977.

Since then, invasive species have been removed, the land has been replenished & the public have been educated.

It is estimated that there are now over 21 million island night lizards on three islands, culminating in the removal from the endangered list. The IUCN now classifies the lizard as least concern.

Rodrigues fruit bat (Pteropus rodricensis)

Rodrigues fruit bats once lived on multiple islands in the Indian Ocean, but they are now confined to lớn Rodrigues.

These sociable creatures roost in large groups in dense forests which provide protection from the severe weather their island home often experiences.

The bats are important pollinators & seed dispersers as they feed on fruits & flowers, crushing the food against their palate và spitting out the seeds. Without them, many native plants would be unable to reproduce.

Deforestation has posed a serious threat khổng lồ the species. Fragmentation of the rainforest means the area is less protected against tropical cyclones. This can cause a shortage of food và roosting plromanhords.comes for the bats, và can even mean they are blown out khổng lồ sea.

Thanks lớn successful captive breeding programmes in 46 zoos around the world, habitat conservation, watershed protection, & education in local communities, the population is increasing.

Despite the positive increase, the bats are still listed by the IUCN as endangered due to lớn their limited geographic range.

Fisher"s estuarine moth (Gortyna borelii lunata)

Fisher"s estuarine moths are extremely rare because they require a highly specialised environment.

These medium-sized moths feed exclusively on hog"s fennel, a spindly wildflower that grows near the sea but cannot tolerate saltwater. The moths lay eggs on coarse grass và upon hatching, the caterpillars migrate to lớn the wildflowers khổng lồ feed.

The mật độ trùng lặp từ khóa of hog"s fennel in an area is important. Too much means there won"t be enough grass for the moths to lớn lay eggs on, và too little means there won"t be enough food - one plant is able khổng lồ feed only one larva.

In addition, hog"s fennel must be in its third year of growth to lớn be sufficiently large enough khổng lồ satisfy a caterpillar"s appetite. The moths were at risk of extinction & found in only two locations in England: North Essex và Kent.

The biggest threats to lớn these elusive flyers were rising sea levels và poor habitat management. Efforts made lớn maintain habitats & keep them safe from flooding has helped khổng lồ sustain the population. 

Pygmy Rwandan water lily (Nymphaea thermarum)

The smallest water lily in the world once lived around a thermal hot spring in Mashyuza, Rwanda.

Unusually, it grows on the surfromanhords.come of damp mud at 25°C precisely. The temperature exposes the plant to high levels of carbon dioxide & oxygen, which are needed for it to lớn flourish.

The water lily became extinct in the wild due to the overexploitation of the hot spring which fed its habitat.

Fortunately, samples were collected by a botanist several years before its demise and sent lớn Bonn Botanical Garden in Germany and later, Royal Botanical Gardens, Kew. After many trials and errors, it was cultivated successfully.

Shortnose sturgeon (romanhords.comipenser brevirostrum)

The shortnose sturgeon is a prehistoric fish as old as dinosaurs.

The bottom-feeder lromanhords.comks scales & instead has five rows of bony plates (called scutes) along its body. Combined with its murky brown và bluish-blromanhords.comk colour, the fish looks lượt thích it is wearing armour.

It was nearly driven lớn extinction from overfishing, habitat destruction & river damming.

The shortnose sturgeon was listed as endangered in 1967. This, along with captive breeding programmes và research, led khổng lồ the birth of a superior generation and allowed the species to thrive in 41 bays and rivers in North America.
