摘要: The grey partridge became extinct in the province of Siena (central Italy) late seventies, whereas red‐legged had already disappeared by beginning twentieth century. Some reintroduction attempts both species carried out 1980s gave encouraging but not definitive results, and failed after an initial success. This was probably due to low number birds released, small size re‐introduction areas, their isolation, farm‐bred origin partridges, hunting. In Siena, for first time Italy, a large‐scale program partridges experimented. project started up 1995 with seven areas four partridge, extended 19 (22,562 ha) 7 (6858 2002. Population viability analyses showed that if reintroduced populations were isolated they would be few years. Theref...
