Unintentional wildlife poisoning and proposals for sustainable management of rodents.

摘要: In Europe, bromadiolone, an anticoagulant rodenticide authorized for plant protection, may be applied intensively in fields to control rodents. The high level of poisoning wildlife that follows such treatments over large areas has been frequently reported. France, bromadiolone used water voles (Arvicola terrestris) since the 1980s. Both regulation and practices rodent have evolved during last 15 years restrict quantity poisoned bait by farmers. This led a drastic reduction number cases reported French surveillance network SAGIR. During autumn winter 2011, favorable weather conditions vole densities staging several hundreds Red Kites (Milvus milvus) Puy-de-Dome department (central France). At same time, intensive with were performed this area. Although no misuse mentioned authorities following controls, 28 16 Common Buzzards (Buteo buteo) found dead surveys November December 2011. For all these birds, as main cause death was either confirmed or highly suspected. Other observations suggest possible impact on breeding population area spring protection is currently under revision, we believe event calls more sustainable management outbreaks. Based large-scale experiments undertaken eastern propose direct at low density (with trapping limited chemical treatments) mechanical destruction tunnels, mole control, landscape management, predator fostering included future because could help resolve conservation agricultural issues.
