La loutre sur la Drôme : analyse des facteurs limitants

Description :
The species still exists in this river basin, as well as in the Rhône, close to the mouth of the Drôme, forming two population isolates. The scarcity of otters in this area is probably not ascribable to changes in water quality or prey availability, but to anthropic factors. Proposals are made to ensure a better protection of these relict populations.
