Maintaining the
movement of animals between populations is crucial to maintaining
their viability. In an ideal world, habitat would allow animals to
move on their own. However, populations of some species, such as
brown bears, are so fragmented that movements between populations
are impossible. In such cases humans have to assist by translocating
individuals. For example, this form of population reinforcement lies
behind the release of Slovenian bears in the French Pyrenees. in
late October 2006, the first bear was moved from western to eastern
Serbia in an attempt to reinforce the small population there. This
103 kg female, called Djura, was released on October 30th. More bears are
expected to be moved in spring 2007. |
