Summarize this article for a 10 year old
Pleistocene Park (Russian: Плейстоценовый парк, romanized: Pleystotsenovyy park) is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to re-create the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period.[1][lower-alpha 1]

The project is being led by Russian scientists Sergey Zimov and Nikita Zimov,[3][4][5][6][7] testing the hypothesis that repopulating with large herbivores (and predators) can restore rich grasslands ecosystems, as expected if overhunting, and not climate change, was primarily responsible for the extinction of wildlife and the disappearance of the grasslands at the end of the Pleistocene epoch.[8][9]
The aim of the project is to research the climatic effects of the expected changes in the ecosystem. Here the hypothesis is that the change from tundra to grassland will result in a raised ratio of energy emission to energy absorption of the area, leading to less thawing of permafrost and thereby less emission of greenhouse gases.[8][9] It is also thought that removal of snow by large herbivores will further reduce the permafrost's insulation.
To study this, large herbivores have been released, and their effect on the local flora is being monitored. Preliminary results point at the ecologically low-grade tundra biome being converted into a productive grassland biome and at the energy emission of the area being raised.[10]
