Eurasian otters originally had a distribution throughout the Czech Republic. As a result of hunting for fur, and a deterioration in water quality and food supply, there was a strong decline in numbers in the 20th century. Due to this rapid decline, the otter became classified as a protected species. Since the late 1980s, however, there has been a significant increase in their distribution area. Due to this increase, doubts are being raised about the purpose of protecting otters and the creation of a care program for this species. Despite both of these points, the Eurasian otter is still exposed to significant risk factors such as traffic growth and illegal hunting and it is for these reasons why active protection is still in place.
The aim of the project was to obtain demographic data on the population of the Eurasian otter in the Czech Republic, which will serve as a basis for quantitative models of population viability. These data and models have helped us understand how the population functions, showed us where there are risks to the population and how large they are and even allowed us to work out the evolution of the population, in simulated management measures.
The project also included setting up a nationwide collection of dead otters, creating information channels, protocols and a network of cooperating organisations.
