Why are conservationists releasing deer for Amur tigers?

Question

Accepted Answer

Conservationists are releasing deer to bolster the prey base for the endangered Amur tiger population in northeastern China.

Conservation efforts in northeastern China involve releasing deer into the wild to increase the food available for the critically endangered Amur tiger. This initiative aims to address the severe decline in the tiger population, which is largely attributed to a scarcity of prey. The Amur tiger, also known as the Siberian tiger, faces a precarious existence with only approximately 20 individuals estimated to remain in the wild in China.
Low Prey Numbers Threaten Tiger Survival

The Amur tiger population in China has been significantly impacted by a lack of sufficient prey. Conservationists highlight that the number of prey animals, such as deer and wild boar, in China is notably lower compared to other regions where Amur tigers are found. For a single Amur tiger to survive, it is estimated to require approximately 50 deer or wild boar annually. To sustain such predation rates, a prey population around ten times that number is considered necessary.
Efforts to Rebuild Prey Populations

Organizations like the World Wide Fund for Nature (WWF) are actively involved in projects to increase deer numbers within protected areas, such as the Jilin Wangqing National Nature Reserve. In 2012, 37 deer were released into the area, and a similar number were released in the month preceding the report. These releases are part of a broader strategy to support not only the Amur tiger but also the even more endangered Amur leopard.
Habitat Protection and Corridor Connectivity

The Wangqing reserve is strategically located as part of a crucial corridor that connects Amur tiger populations in China and Russia. To support this connectivity and the recovery of tiger populations, significant steps have been taken to reduce logging activities in the region. Furthermore, initiatives are in place to provide alternative income sources for forest workers, thereby diminishing reliance on logging and its impact on tiger habitats.
Historical Context and Global Tiger Decline

Historically, Amur tigers once roamed Manchuria in the hundreds, but human settlement, logging, and poaching have drastically reduced their numbers. Worldwide, wild tiger populations have fallen from an estimated 100,000 a century ago to between 2,700 and 3,200 today. While Russia has seen an increase in its Amur tiger population due to protection efforts, China faces the challenge of rebuilding its own population, emphasizing the need to avoid infrastructure projects that could fragment vital tiger habitats.
