Large mammals such as rhinos, elephants and even deer are at high risk of extinction in some of the world’s poorest national parks, according to new international reports.

Studies have found that worldwide, strong protected areas show levels of decline in mammals. This was not the case in Asia however, where national parks had a high rate of poaching and the decline of species.

During the Pleistocene, 40,000 to 10,000 years ago, North America lost more than 50% of its large mammal species. These species include giant sloths, mastons, mammoths and many others.

The large mammals extinction risk is higher. This is often thought to be simply because the methods of endangered species, such as low birth rates, are measured by body size.

In the four continents surveyed, 294 different species of mammals were found hunted in national parks designed to protect them. Studies of birds and mammals have shown that those with large bodies are more likely to die.

The types of disasters facing poor countries are likely to be exacerbated by the lack of conservation resources. To protect biodiversity, governments and policymakers need to focus on tackling human poverty, researchers urged.

In a detailed analysis of the risk of large mammals extinction, two additional patterns in the size selection of extinction species have been found.

First, the effects of both internal and external factors are greatly increased beyond the physical limit of approximately 3 pounds. Second, while the risk of large mammals extinction is driven by environmental factors, the larger species are driven by a combination of environmental and internal factors.

Therefore, the magnitude of the large size and the future loss of a variety of large mammals may be much faster than expected.

The review, which looks at 81 studies conducted between 1980 and 2020, found that poaching causes a disturbing decline in many large mammals extinction in the world’s protected areas, especially in poor countries.
