We spent the autumn adapting the 27 Kampinos cellars to accommodate overwintering amphibians. The basic and most important measure was to make the exit clear by building ramps on the existing stairs. This will enable the animals to get out of the cellars unhindered in spring. In addition, we provided them with convenient shelter inside the cellars by placing wooden gangways, decaying wood, leaves and ceramic elements. This measure is aimed at improving the amphibian population in the Kampinos National Park, primarily the great crested newt, which has taken a liking to parts of the cellars for wintering. Of course, in addition to it, other amphibian and reptile species will also benefit.
