Setting population targets for mammals using body mass as a predictor of population persistence ArchiMer
Hilbers, Jelle P.; Santini, Luca; Visconti, Piero; Schipper, Aafke M.; Pinto, Cecilia; Rondinini, Carlo; Huijbregts, Mark A. J..
Conservation planning and biodiversity assessments need quantitative targets to optimize planning options and assess the adequacy of current species protection. However, targets aiming at persistence require population-specific data, which limits their use in favor of fixed and non-specific targets, likely leading to unequal distribution of conservation efforts among species. Here we propose a method to derive equitable population targets, which are quantitative targets of population size that ensure equal probabilities of persistence across a set of species, and can be easily inferred from species-specific traits. We applied population dynamics models across a range of life-history traits representative for mammals, and estimated minimum viable population...

The Ghost of Extinction: Preservation Values and Minimum Viable Population in Wildlife Models AgEcon
van Kooten, G. Cornelis; Eiswerth, Mark E..
The inclusion of a minimum viable population in bioeconomic modeling creates at least two complications that are not resolved by using a modified logistic growth function. The first complication can be dealt with by choosing a different depensational growth function. The second complication relates to the inclusion of the in situ benefits of wildlife into the analysis. Knowledge about the magnitude of the in situ benefits provides no guide for policy about conservation management. Simply knowing that people are willing to pay a large amount each year to protect a species says nothing about whether one should manage habitat to protect or enhance the species’ numbers, unless the species is in imminent danger of extinction. If willingness to pay is to be a...
