Male mountain nyalas (Tragelaphus buxtoni)

Species: Mountain nyala (Tragelaphus buxtoni)

Status: Endangered (EN)

Interesting Fact: The male mountain nyala is larger than the female, and has long, spiralling horns, which may grow to 118 centimetres long. As the male matures, the tips of its horns develop an ivory colouration.

More information: The mountain nyala is an elegant and rather attractively marked antelope and is endemic to the highlands of Ethiopia, where it is found to the southeast of the Rift Valley. Most active in the evening and early morning, the mountain nyala browses on bushes, trees and herbs, and will also take grasses, ferns, aquatic plants and lichens. Individuals often shelter in dense cover such as woodland and heather during periods of extreme cold or heat, and the attractive markings may help to conceal individuals from predators by breaking up its outline.

The mountain nyala population has undergone a substantial decline in recent decades, and has decreased from an estimated 7,000 to 8,000 individuals in the 1960s to perhaps fewer than 4,000 today. The range of the mountain nyala has been reduced dramatically, and the remaining populations have become fragmented, which has made them particularly vulnerable to population declines. The main threats to the mountain nyala come from the negative effects of human activities throughout its range, with increasing human and livestock populations putting ever-increasing pressure on this species through illegal hunting, competition with cattle and predation by domestic dogs, as well as habitat clearance for agriculture, grazing, firewood harvesting, and settlement. Despite being fully protected by law, enforcement of legislation is generally absent, and the mountain nyala is only effectively protected within a small area in the north of Bale Mountains National Park. The mountain nyala is a flagship species for conservation in Bale Mountains National Park, but its future survival will depend on increased protection from illegal activities, and action to reduce or manage human utilisation of the park.

Birdlife’s recent assessment of 350 newly recognised bird species, on behalf of the IUCN Red List, has found that 25 percent of these species are at risk of extinction. Around 13 percent of all known bird species are considered to be at risk, showing that the conservation of these newly recognised species needs to be prioritised.

This recent study focussed on non-passerine birds, such as birds of prey, owls, seabirds and waterbirds. There are 4,472 non-passerine birds known to science, of which 361 were found to be distinct species during this recent assessment. The identification of these new non-passerines shows that previous species counts have underestimated the true diversity of this avian group by around 10 percent.

Just a few Bugun liocichla breeding pairs have been found in eastern India and the species has been reclassified as Critically Endangered

One finding of the study was that an ostrich subspecies, the Somali ostrich, is in fact a distinct species and has now been classified as Vulnerable. Andy Symes, BirdLife’s Global Species Officer, said, “This species highlights both the need for improved knowledge of the world’s birds and the need for conservation action in some of the most challenging parts of the globe.” It is hoped that the early recognition of these threatened species will provoke action to ensure their future survival.

Despite the recovery of the lammergeier in Europe, the species is declining globally and has been upgraded from Least Concern to Near Threatened

Various species have also been reassessed to determine whether their Red List classification is currently correct. The population size of many species has dramatically decreased, leading to reclassification. In some species, such as the lammergeier, it was found that the population is becoming larger in certain areas but is declining in others.

The newly recognised Javan blue-banded kingfisher has entered the IUCN Red List as Critically Endangered

The importance of bird hotspots was also highlighted during the assessment, especially those that are home to many endemic species. These habitats, along with the bird species that live within them, are in desperate need of conservation action to ensure their future survival. Dr Stuart Butchart, BirdLife’s Head of Science, said, “The IUCN Red List is crucial not only for helping to identify those species needing targeted recovery efforts, but also for focussing the conservation agenda by identifying the key sites and habitats that need to be saved, including Important Bird and Biodiversity Areas.

Plans for a new opencast mine near South Africa’s Hluhluwe-Imfolozi reserve may increase pollution and poaching in the area, which would lead to further reductions in the size of the local southern white rhinoceros population. 

Among the most charismatic and recognisable of Africa’s mega-fauna, the white rhinoceros is the largest of the five rhinoceros species and one of the world’s biggest land animals, second only to the African and Asian elephant in size. A subspecies of white rhinoceros, the southern white rhinoceros, is currently the most numerous of all the world’s rhinos, and 93 percent of the total population is thought to occur in South Africa. This subspecies was rescued from near extinction a century ago, and represents a real conservation success story. In 1895, only around 50 individuals remained but careful conservation has increased this number to the 20,000 individuals that exist today. However, threats to the southern white rhinoceros are on the increase, and news of a proposed mining operation in close proximity to one of the most important nature reserve for this, and many other, species may spell disaster for this iconic animal.

The Near Threatened southern white rhinoceros is currently the most populous of the world’s rhinoceros species

The Hluhluwe-Imfolozi Park in KwaZulu-Natal province of South Africa is the oldest nature reserve in Africa and was established in 1895, largely to protect the remaining population of the southern white rhinoceros. Situated at the confluence of the Black and White Umfolozi Rivers, this natural reserve is home to Africa’s ‘big five’, as well as innumerable other iconic species and over 340 bird species. There are fears that opencast coal mining in close proximity to the park may pollute the air and rivers, displace local communities, and threaten the southern white rhinoceros. Local communities’ fears are founded in experience, they say that drilling and blasting at the Somkhele coal mine, six miles away, already creates pollution and affects livestock. There are concerns that not only will the toxic dust from the new mine affect the local wildlife, but the influx of people is also likely to increase the accessibility of the park to poachers.

The African leopard is also found in the Hluhluwe-Imfolozi Park

Poaching is an increasing threat to all rhinoceros species. Just 13 rhinoceros were killed in 2007, while recent figures show that over 500 have been killed so far in 2014, indicating the highest level of poaching since records began. The growing demand for rhinoceros horn is thought to be due to economic growth and increased disposable income in Southeast Asia and China, where the horn is used for traditional medicine and as a sign of prestige among the business elite. The price of rhinoceros horn is greater than that of gold, and poachers are becoming increasingly organised, and there have been many reports of helicopters and high-tech gadgetry being used in poaching attempts. It is thought that the mine could help to facilitate poaching, and increase the difficulty of policing the park. The response to the plans from local communities and conservationists worldwide has been one of concern and consternation.

The Galápagos archipelago is known for its extraordinarily rich abundance and diversity of native plants and animals found nowhere else in the world. However invasive species present on islands are threatening the Galápagos’ rare species, pushing many to the brink of extinction. To date, seven vertebrate species have become extinct, while 40% of the still existing 96 species are endangered – with invasive species as the primary threat.

The world’s only marine lizard, the endemic Galápagos marine iguana, is extremely vulnerable to invasive species which consume the young and even occasionally adults

Island Conservation began working to protect species in the Galápagos Archipelago in 2008. In 2011,  the Galápagos National Park, supported by Island Conservation, Charles Darwin Foundation, The Raptor Center, and Bell Laboratories, removed invasive rats from the islands of Rábida, North Plaza, three Beagle islets, and three of the Bainbridge Rocks to protect 12 unique Galápagos species considered by the International Union for Conservation of Nature to be threatened with extinction.  One success story from this project was the rediscovery of a land snail species on Rábida Island, which was presumed to be extinct as no live specimens had been observed or recorded since 1905-1906.

In 2012, work began to remove invasive species from another island in the Galápagos Archipelago, Pinzón Island. Over 150 years ago, invasive black rats invaded this island and began feeding on the defenceless eggs and hatchlings of the Pinzón giant tortoise. By the turn of the 20th century the island endemic tortoise was unable to establish its next generation of tortoises, resulting in a captive rearing program being set up.

By December 2012, the project to remove the invasive rat species from this island was completed. With the removal of the last remaining invasive vertebrate species threat, tortoise hatchlings are now emerging from native tortoises on the island and the Galápagos National Park have successfully returned 118 hatchlings to their native island home.

The removal of invasive species from these islands is part of a much larger project to restore other key Galápagos Island ecosystems to protect native plants and animals. The next major endeavour is to remove multiple invasive species from Floreana Island. Feral goats have already been removed from the island, but other invasive species remain which are a threat to the island’s rich biodiversity. This rich biodiversity includes the Critically Endangered Floreana mockingbird which has disappeared from the island, mainly as a result of invasive species. Now only surviving on two small neighbouring islets, the removal of invasive rats and cats from Floreana will allow for this bird to comeback from the brink of extinction.

Over 200 hundred years ago, the United States declared its independence and became its own sovereign nation. Often celebrated in America with BBQs and fireworks, the universal color scheme for any gathering today includes red, white and blue.  We thought we’d celebrate the 4th of July here at Arkive… but with our own wildlife twist!

Check out our favorite red, white and blue wildlife mascots for Independence Day this year!

RED – North Pacific giant octopus

We could actually put the North Pacific giant octopus under the red and the white category since the species contains special pigment cells in the skin called chromatophores that, when activated, cause the octopus mantle to change colors from red to white. True to its name, the North Pacific giant octopus is the largest of all octopus species and can be found off the entire Pacific coast of the US.

White – Polar bear

The most well-known of all bears, the polar bear is immediately recognisable from the distinctive white colour of its thick fur. Did you know that the only unfurred parts of the body are the foot pads and the tip of its nose? The largest land carnivore, the polar bear calls the snowy habitat of Alaska home.

Blue – Blue whale

Despite its common name, the blue whale is actually grayish-blue and can even have a yellowish tinge caused by microscopic algae called ‘diatoms’. The blue whale is found in every ocean in the world except the Arctic!

Can you name some other North American RED, WHITE and BLUE animals?  Feel free to name some in the comments section and take a look to see if you can find them in the Arkive website.

From Arkive, we hope you have a happy and safe 4th of July!
