| Abstract |
|
At present, the last native population of Western Hermann’s Tortoise in the Iberian Peninsula is located in north-west of Catalonia, within Albera Natural Park (Fèlix et al 2006). This tortoise population is critically endangered, with just 1 to 2 individuals/ha as a result of multiple extinction drivers. In recent years the “Departament de Medi Ambient i Habitatge de la Generalitat de Catalunya” and the “Agència de Gestió d’Ajuts Universitaris i de Recerca” have supported several field studies including tortoise radiotracking, habitat requirements, species distribution and new control strategies of nest predation. In the last radiotracking study (2009- 2010) we radio-marked 40 tortoises: 30 wild adults and 10 juveniles from a breeding captivity program. The radiotracking of the 30 adults has allowed us to determine which type of habitat is used every season and we concluded that the mosaic of micro-habitats is favourable. On the other hand, the study of the 10 juveniles was aimed at determining if organic vineyard can be favourable to the tortoise population. We observed that a high percentage of the young tortoise released in the vineyard used inner corridors as shelter and feed. We also modified and improved the potential distribution model generated in 2007, adding new environmental variables (neglected fields, etc). Finally, we tested the efficacy of new strategies of nest predation control (creation of new nesting areas and use of enclosures to protect them) following the results obtained in a study of predatory species identification with trail cameras.
