Large carnivores are key components of forest ecosystems in the Carpathians, hosting one of the most abundant native populations of lynx, wolf and bear in Europe. However, whether populations are stable or growing is unclear as data are not collected in a harmonised way across borders, with no shared regulations and policies on large carnivores conservation (eg. poaching prevention), and no shared understanding and coordination between stakeholders. Clear is, however, that perceived and real conflicts between humans and large carnivores are on the rise. In order to promote coexistence with local stakeholders, to enable viable large carnivores population structures, natural expansion and recolonisation of large carnivores, to establish evidence-based and coordinated practices in the Carpathian countries, and to contravene misconceptions, LECA wants to to raise awareness, educate, engage and influence target groups such as hunters, foresters, farmers, livestock and beekeepers, police investigators (poaching), ministries, municipalities and the broad public. The project aims are (1) a consistent and efficient monitoring approach involving local stakeholders; (2) up-to-date population information in cross-border regions; (3) effective conflict prevention measures to be rolled-out at Carpathian level; and (4) an improved participative cooperation of key actors at local, regional and transnational level. A Thematic Guidance on large carnivores conservation and coexistence in the Carpathians will be created and validated via pilot actions in cross-border pilots (Tatras (SK/PL), East Carpathians (SK/PL/UA), Slovak Karst - North HU Mountains (SK/HU), Beskydy-Kysuce (CZ/SK)) and reference areas (SL/RO), driving pilot area strategies, national recommendations and an IT app for the public. The Guidance will cover novel, unified tools for harmonised Monitoring, Poaching investigation and Conflict prevention.
