Conservation and control strategies for the wolf (Canis lupus) in western Europe based on demographic models.

摘要: Securing the long-term acceptance of large carnivores such as wolf (Canis lupus) in Europe and North America raises a difficult challenge to conservation biologists: planning removals reduce depredations on livestock while ensuring population viability. We use stochastic-stage-structured models investigate dynamics assess alternative management strategies. Among various strategies advocated by agencies, zoning that involves eliminating wolves outside restricted area should be designed with caution, because probabilities extinction are extremely sensitive maximum number packs zone can support slight changes stage specific survival probabilities. In zoned population, viability is enhanced more decreasing mortality rates all classes than increasing size. An adaptive management, where there no limit pack but control operated whenever some predefined demographic conditions met. It turns out an strategy removes moderate percentage (10%) following each year 5% total growth would provide visible actions addressing public concerns keeping probability low.
