By Center for Conservation Innovation/Conservation Strategies Unit, 2002, World Wildlife Fund (WWF) This sourcebook has been designed to give practitioners guidance in how to undertake or collaborate in population-related assessments and actions. It includes the following: information on how population dynamics affect ecoregions and a summary of current and projected population trends; a set of questions to help assess population-environment interactions at ecoregional and site-based levels; suggestions for specific actions to address population dynamics, including information on partnerships; information on what impacts can be expected from specific interventions, and in what time frame; and resources to support practitioners' efforts to act on population-conservation connections.
