Translated from national park De Hoge Veluwe in the eastern Netherlands:
In the Park, nipple lichen has been discovered during an investigation of sand dunes by the universities of Amsterdam, Wageningen and Nijmegen in various sand dune areas in The Netherlands, including the Hoge Veluwe.
This lichen had recently become extinct in The Netherlands; however, now it has been found again in the Park.
It is a small specimen, less than one square decimeter in size.
Nipple lichen (Pycnothelia papillaria) is a mountain species, which is in trouble because of global warming.
Also, acidification and too much fertilizer has really hurt the species.
Probably, the species will not last long at De Hoge Veluwe; yet, finding it is spectacular.
There are many lichens at De Hoge Veluwe.
Many of its open plains are so called lichen steppes, which have become rare in western Europe.
