Assessing the Nature Reserve Management Effort Using an Expert-Based Threat Analysis Approach

In this note, we suggest the adoption of expert-based approaches for threat analysis to allow an assessment of the magnitude of efforts of wildlife management actions. Similar to what is proposed for expert-based quantification of threat events, in wildlife management this approach can be applied by assigning a score to the extent of the areas affected by management, their frequency and intensity of action, supporting the decision-making process and optimizing the management strategies, both ordinary (for example, in the operational management of nature reserves) and extraordinary (for example, within specific target-oriented conservation projects). Quantifying and defining priority ranks among management events can be useful: (i) to compare managed areas with each other or the same areas in different times; (ii) to adjust the allocation of resources among alternative management actions (assigning more or less resources in terms of time, budget, operators, and technology). Finally, similar to what is done in the threat analysis approach, managers could compare the effort (magnitude) of management at different times. We report, as an example, a first quantification for a case study carried out in a coastal nature reserve.
