what is the relationship between deforestation and endangered animals

Deforestation can have a negative impact on the environment. The most dramatic impact is a loss of habitat for millions of species. Amazon's doomed species set to pay deforestation's 'extinction debt' are endangered largely because of the expansion of farmland and road. Previous analyses have used a reverse species-area relationship to worst— led to unrealistic estimates in globally endangered species that.

The endangered giant otter, found in the slow-moving rivers and swamps of the Amazon, faces water pollution from agricultural runoff and mining operations in the area. But that is going to move in the future.

Under the "business as usual" scenario, where around 62 sq miles sqkm of forest are cleared each year, at least 15 mammal, 30 bird and 10 amphibian species were expected to die out locally byfrom around half of the Amazon. Under the most optimistic scenario, which requires cattle ranchers and soy farmers to comply with Brazilian environmental laws, the extinction debt could be held close to 38 species.

Losing their homes because of the growing needs of humans

Ewers said the model reveals hotspots in the Brazilian Amazon where conservation efforts should be focused on the most vulnerable wildlife. We are talking about an extinction debt. Those species are still alive, so we have an opportunity to get in there and restore the habitat to avoid paying that debt," Ewers said.

The trend towards less deforestation might not last though. Under pressure from the financial crisis, the Brazilian government has proposed a rapid development programme in the Amazon to fuel the economy.

The move foresees the construction of more than 20 hydroelectric power plants in the Amazon basin and an extensive push into the rainforest. Reducing the rate that extinction debts build up is not enough to preserve the Amazon's biodiversity, Rangel argues.

The updated species range maps used are available on request. Abstract Tropical forest diversity is simultaneously threatened by habitat loss and exploitation for wildlife trade.

Quantitative conservation assessments have previously considered these threats separately, yet their impacts frequently act together. We do so for forest-dependent bird species, of which 77 are commercially traded, in the Southeast Asian biodiversity hotspot of Sundaland. Combined assessment of major threats is vital to accurately quantify biodiversity loss.

Amazon's doomed species set to pay deforestation's 'extinction debt'

Introduction Tropical forests are the most biodiverse ecosystem globally 1. In recent decades, there has been an extensive loss-of-tropical forests, driven primarily by the expansion of agricultural land 2 — 4.

This loss has serious consequences for tropical biodiversity, as the destruction of suitable habitat threatens the survival of forest specialist species.

Anthropogenic disturbances within remaining forest, including logging, fires, hunting, trapping, and edge effects, are also serious drivers of biodiversity declines 5. Illegal hunting of wildlife for internationally traded products, pets and as a food resource are directly responsible for the declines of emblematic species, such as elephant 8rhinoceros 9tiger 10and Bali starling
