Mapping of events of the presence of the Marsican brown bear

The database returns the events of the presence of the Marsican brown bear in the regional territory in the form of a grid of 2 km x 2 km. The events of presence are defined on the basis of the signs of presence detected and then validated by the contact persons of the Regional Monitoring Network of the Marsican Brown Bear according to the standards set out in the technical document “Criteria for the planning of the monitoring of the presence of the Marsican brown bear in peripheral areas of the distribution area in the Lazio Region”. Attendance events span a time span from the 1990s to 2021. The grid does not represent the distribution of the population on the regional territory but the events of presence documented and validated to date. The presence events integrated with the cartography of distribution models and environmental suitability for the species (downloadable from the site of the Ministry of the Environment and the Protection of Land and Sea at http://www.minambiente.it/pagina/piano-dazione-la-tutela-dellorso-marsicano-patom) are an indispensable information layer for the territorial management aimed at the conservation of the Marsican Brown Bear population. Since 2015, the Association Salviamo l’Orso collaborates with the activities of the Regional Monitoring Network of the Marsican brown bear through a joint monitoring programme in the Ernici Mountains area.
