I would be curious to know where they got it from as well. Some preliminary searching doesn't turn up any solid info, but does turn up that the one person they quote by name, Jean-Marc Landry, previously worked on a project to reduce conflicts between shepherds and the reintroduction of wolves (http://www.kora.ch/en/proj/cdpnews/cdpnews001.htm#Landry), so it's plausible he'd be working on something like this.
