Conservation in the United States is funded largely by hunters and anglers, however, the number of licensed hunters is exhibiting a long-term decline. Recruitment, retention, and reactivation (R3) of participants in conservation-related recreation is paramount to preserving our outdoor heritage. However, restricted funds and inadequate personnel time limit R3 efforts. Therefore, it is crucial to evaluate the efficacy of R3 programs and strategies to invest resources into the specific programs that are most effective. To address this, the Wildlife Management Institute, in conjunction with Chase & Chase Consulting, is working to develop and implement an approach to evaluating R3 programmatic impact directly by using license data from participating states to document hunter behavior across time.
