Research: the role of monitoring in wildlife conservation
 
Progress is only possible if we know whether our activities are having the desired effects. There has been a flurry of targets and priority-setting in conservation recently, such as the Millenium Development Goal of reducing the rate of biodiversity loss by 2010. This has coincided with an increasing recognition that good quality monitoring is both essential to reducing biodiversity loss, and involves serious intellectual challenges. There is a fast-growing interest in evaluating the success of conservation interventions as well as some recent progress on evaluating cost-effectiveness of conservation action.

However, as well as monitoring to assess the outcome of a conservation strategy, two other types of monitoring are essential to successful conservation. These are monitoring of individual behaviour to ensure compliance with rules and agreements, and monitoring to detect, and act upon, ecological trends. The first of these has received particularly little attention in the literature, partly because the study of compliance is unfashionable and seen as counter to the paradigm of community participation in conservation, and partly because the intellectual tools required are within other disciplines (game theory, economics, fisheries science). Monitoring for detection of biodiversity trends has received more attention. However, monitoring is costly and more attention from both ecologists and economists, explicitly taking account monitoring costs and the costs associated with inference errors about trends of interest, is urgently needed to improve the design of effective protocols.

 

In this theme we consider the bio-economics of monitoring in wildlife conservation. Early work included an assessment of the incentives to hunt illegally for elephants and rhinos in the Luangwa Valley, Zambia. Our new work develops and extends these ideas into new areas, and has a particular focus on Madagascar.
