Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building.

In the tundra landscape, they nest on the ground and during hot weather, they could go out of the nest seeking shelter from the sun. If weather then rapidly changes to the thunderstorm (which is common in the Arctic) nestlings could die without parent protection in a short time in 3–5 m from the nest. [ 35 ]
During April and May, the Arctic fox also preys on ringed seal pups when the young animals are confined to a snow den and are relatively helpless. They also consume berries and seaweed, so they may be considered omnivores. [21] This fox is a significant bird-egg predator, consuming eggs of all except the largest tundra bird species. [22]
The Siberian crane (Leucogeranus leucogeranus), also known as the Siberian white crane or the snow crane, is a bird of the family Gruidae, the cranes.They are distinctive among the cranes: adults are nearly all snowy white, except for their black primary feathers that are visible in flight, and with two breeding populations in the Arctic tundra of western and eastern Russia.
In 1997, there was a decline in the Arctic wolf population and its prey, muskoxen (Ovibos moschatus), and Arctic hares (Lepus arcticus). This was due to unfavourable weather conditions during the summers for four years. Arctic wolf populations recovered the next summer when weather conditions returned to normal. [28]
[7] [42] A more detailed glance at Finnish Lapland showed that amongst 2,062 prey items, 32.5% of the foods were Norway lemmings (though in some years the balance could range up to 58.1%), 28% were grey red-backed voles (Myodes rufocanus) and 12.6% were tundra voles, with birds constituting a very small amount of the prey balance (1.1%).

The carcass of a large cub estimated to be about 3 weeks old was found encased in a block of ice in the Republic of Sakha, located in Russia's Far East, along the Badyarikha River in 2020 ...
The degree of feeding activity depends on the tide, weather, season and the behaviour exhibited by the prey. [33] In New Zealand, female L. l. baueri has a probe rate of 26.5 probes per 4 minutes period which is 1.6 times higher than that of males but the feeding success is observed to be similar in both sexes.
