| Uncertainty is a dominant feature of decision making in forestry and wildlife management. Aggravating this challenge is the irreversibility of some decisions, resulting in the loss of economic opportunities or the extirpation of wildlife populations. We adapted the real options approach from economic theory to develop a methodology to evaluate a resource management decision to stop timber harvesting when a woodland caribou (Rangifer tarandus caribou) population becomes threatened with extinction. In our study area of central Labrador, Canada, both caribou and timber harvesting are valued ecosystem services. By using a decision rule, which incorporates future developments, the real options approach provides a technique to incorporate ecological and social... |

| We investigated wildfire-related effects on a slow ecological variable, i.e., forage production, and fast social-ecological variables, i.e., seasonal harvest rates, hunter access, and forage offtake, in a moose–hunter system in interior Alaska. In a 1994 burn, average forage production increased slightly (5%) between 2007 and 2013; however, the proportional removal across all sites declined significantly (10%). This suggests that moose are not utilizing the burn as much as they have in the past and that, as the burn has aged, the apparent habitat quality has declined. Areas with a greater proportion of accessible burned area supported both high numbers of hunters and harvested moose. Our results suggest that evaluating ecological variables in... |

| 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... |

| This report is intended to be a West African contribution to a global study of IIED on community wildlife management issues. Its geographic focus is the 16 member countries of the Economic Community Of West African States (ECOWAS), including 9 francophone countries (Benin, Burkina Faso, Niger, Mali, Ivory-Coast, Mauritania, Senegal, Guinea,Togo), 5 anglophone countries (Ghana, Liberia, Nigeria, Sierra Leone, The Gambia) and 2 lusophone countries (Guinea Bissau, Cape Verde). This region has more than 200 million inhabitants. Eight (8) of the 16 countries concerned are part of the Sahelian region, and are members of the Permanent Interstate Committee for Drought Control in the Sahel (CILSS)1. The remaining ones are generally considered as being better... |
