Experts from the three countries agreed that a lynx population counts 60-80 adults.
Šumava National Park and Bavarian Forest collaborate on research lynx since the nineties and since 2009 across the board uses a method called. Fotomonitoringu - use cameras with an automatic trigger that allows individual recognition of individuals.
"Based on the results of our joint long-term monitoring, we can say that the number of individuals have shot and also identified on both the national parks has long been essentially unchanged. Adult lynx cat inhabits a territory with an area of about 350-450 km2, then the cat 120-150 km2, population density varies between 1-1,6 individuals / 100 km2, "says zoologist Administration Sumava NP Elisa Belotti.
Due to the size of their territories, lives most of the features only in national parks. Their home ranges are partly or completely outside of protected areas (see map ) is therefore to identify the entire population sizes necessary mapping of individuals outside the core area, ideally in the area of occurrence.
"As part of the Trans-Lynx, implemented in 2013-2015, we have to pay attention to the question of the overall population size. Collaboration of experts from the Czech Republic, Bavaria and Austria enabled us to calculate features in the outlying areas, including the features of the border - that is, those who live in the territory of two or even three states. We found that the total population size is 60-80 individuals, and this number does not increase the population stagnating, "says Tereza Mináriková of ALKA Wildlife.
The results of the monitoring of the 90s of last century, when the lynx population in the peak phase of expansion, we know that lynx used more territory cross the mountains than it is today.
"In the last decade, but some outlying parts of the lynx disappeared. In addition, the small size of the Czech-Bavarian-Austrian lynx population is still relatively isolated, which significantly increases its vulnerability. So that the population could survive, it is necessary to be able to expand further. But this is currently not the case. "Says Elisa Belotti.
"On the territory of national parks with features quite successful. Every year there seeing reproduction, and shows how our collective fotomonitoring, bobcats here live longer than individuals surveyed in the framework of the Trans-Lynx outside national parks. Only national parks but to rescue the entire population is definitely not enough. It is important to ensure good conditions for their survival and outside protected areas. Here it is necessary to solve the problems of poaching and especially road transport, "says zoologist Administration of NP.
Monitoring of protected species is one of the basic activities associated with the mission of the national park. Long-term monitoring of the development of the population not only information about ongoing natural processes, but also relevant feedback Business Administration Sumava NP is entrusted territory.
"I am very pleased that this work continues and gets results. We would like to research and monitoring feature further develop and shift to the European level. Together with partners from Bavaria, Austria, Italy and Slovenia so long ago we created together and brought international projects under the grant program Interreg Central Europe, "concludes head of the Nature Protection Department of the National Park Sumava old Martin
