Roadkills as a Method to Monitor Raccoon Dog Populations

The raccoon dog (<i>Nyctereutes procyonoides</i>) is one of the most frequently killed species on Lithuanian roads. As an invasive species, up-to-date knowledge of population size, trends and spatial distribution is critically important both for species assessment and for the planning of...
