Pleistocene Park is a protected area located near the Arctic Circle in the Eastern part of Russia. It was established by Sergey Zimov and his team in order to perform an experiment on the restoration of the environment that existed there during the Pleistocene period. It was expected that low-productivity boreal habitats would be replaced by highly-productive grasslands resembling African savanna. This experiment was launched in 1988, and its continuation is planned for the indefinite future. The territory of the park was surveyed recently and its actual state was characterized.

俄罗斯更新世公园的现状（在北方环境中恢复巨型动物的实验）

更新世公园是位于俄罗斯东部北极圈附近的保护区。它由谢尔盖·齐莫夫 (Sergey Zimov) 和他的团队建立，目的是对更新世时期存在于那里的环境进行恢复实验。预计低生产力的北方栖息地将被类似于非洲大草原的高生产力草原所取代。该实验于 1988 年启动，并计划在无限期的未来继续进行。最近对该公园的领土进行了调查，并对其实际状况进行了表征。
