Ash trees in Europe are classified as “NT” (Near Threatened) by the International Union for Conservation of Nature (IUCN). Ash forests are still found in Belovezhskaya Pushcha National Park, but they grow only on fertile soils with a specific hydrological regime.

A useful feature of this stand is the prominent moss growth on the north side of the ash tree trunks, which facilitates navigation in the remote areas of the national park.
