Altitude: 490–495 m above sea level
Area: 3 ha
Material: washed fine substrate from the copper ore processing factory

 

Copper ore was mined mainly during the 1950s and 1960s at the Bohumír mine, which closed in 1965. Ore was also imported from Slovakia. The substrate from the ore processing factory contains toxic substances that inhibit the development of vegetation. Due to these specific conditions, only a sparse population of dwarf pine and birch trees and sometimes also heather grows there; large areas of vegetation are completely devoid of vegetation. The area is partially flooded and thus provides conditions for the occurrence of wetland species. Management of the site (cutting of trees, mowing of vegetation) has been carried out since 2014 by ČSOP Jaro Jaroměř.
