Lynx were eradicated from the National Park in around 1850, but in the 1970's five to ten were released into the park, along with another 17 released in the Šumava national park a decade later. This resulted in an initially strong increase in the Lynx population in the region, but between 1995 and 2008, the population decreased significantly. This was possibly due to the illegal killing of the animals on both the Czech and Bavarian sides.
