Case studies
Africa’s elephant population has crashed by an estimated 111,000 in the past decade primarily due to poaching. 2016 estimates suggest there are 415,000 elephants across the 37 range states in Africa.
The maned wolf, along with other large mammals including the giant anteater, is threatened by the increasing conversion of grasslands into farmland for grazing and growing crops in the Brazilian Cerrado.
The hellbender salamander underwent population declines of 77 per cent across five locations in Missouri between 1975 and 1995. Degradation of habitat from the effects of agriculture and the recreational use of rivers is believed to be the main cause of the decline.
Orca populations in European waters are under threat from persistent organic pollutants (POPs). Despite legislative restrictions on their use, these pollutants are still present in orcas’ blubber at levels that exceed all known marine mammal toxicity thresholds.
The leatherback turtle has become increasingly rare in both the tropical Atlantic and Pacific. For example, it declined by 95 per cent between 1989 and 2002 in Las Baulas National Park in Costa Rica. This decline was caused mainly by mortality at sea due to individuals being caught as by-catch and by development around nesting beaches. Similar trends have been observed throughout the species range.
The European eel is declining due to disease, overfishing and changes to its freshwater habitat that impede its migration to the sea to breed.
The White-backed vulture, long-billed vulture, slender-billed vulture and the Himalayan griffon have been decimated throughout South East Asia over the past 20 years due to the widespread use of the anti-inflammatory cattle drug diclofenac. The drug causes kidney failure in birds that eat the carcasses of recently-treated cattle.
The Yangtze river dolphin has declined largely due to incidental mortality by collisions with fishing vessels and entanglement in fishing gear An intensive survey carried out in China in 2006 failed to find any evidence that the species survives.
Gharial – India and Nepal: degradation of its habitat, accidental bycatch in fishing nets and harvesting of eggs have led to declines of this critically endangered species of crocodile.
Amphibians – global: A species of fungus that causes chytridiomycosis, a disease of amphibians, is implicated in the steep decline or extinction of more than 200 species.
Major Mitchell’s cockatoo underwent a precipitous population crash in Australia, largely due to the illegal taking of eggs for the pet trade. The population is now slowly recovering due to better enforcement of the law, but the species remains at risk from the clearing of woodland habitat and the destruction of nesting trees.
Tigers – Asia: around 3900 tigers are left in the wild facing threats of habitat destruction, climate change, and human wildlife conflict. The species is critically endangered
Amur Leopards - Asia: As few as 70 Amur leopards are left in the wild, facing threats of habitat destruction and human wildlife conflict. The species is critically endangered.
Giant Panda – Asia: 1864 giant pandas remain in the wild. Threats include human wildlife conflict and climate change. The species is listed as vulnerable.
Mountain Gorillas – Africa: 880 of the critically endangered mountain gorilla remain in the wild facing threats of habitat destruction and human wildlife conflict.
Conservation measures including the preservation of habitat and strict controls on hunting have led to population increases in Europe for the brown bear, grey wolf and Eurasian lynx. Populations have increased by 108 per cent since 1960, 303 per cent since 1970 and 495 per cent since 1963 respectively.
