This project will provide state fish and wildlife agencies (SFWAs) with a reliable, replicable methodology for developing new collaborations with unengaged population segments and novel partner organizations, using existing staff and resources without being heavily reliant on external consultants. The need for agency-led engagement of broader constituencies has emerged from the many pilot projects led by Wildlife Management Institute (WMI) and its SFWA partners in implementing the Fish and Wildlife Relevancy Roadmap. The models most likely to succeed are those that, intentionally or not, identify and empower an existing staff member(s) to serve as a “bridge- builder”—somebody who has the interest and skills to develop and engage a specific constituency in a long-term mutually beneficial relationship with the agency. As the Roadmap was not intended to be, nor written as, an implementation guidance document, there is a critical need to establish specific and tactical approaches for SFWAs to forge relationships with new constituencies by leveraging in-house connections that, if supported, can “build a bridge” between the agency and a new partner. The project team (WMI staff and Clearwater Communications) will collaborate with at least one agency in each of the four Association of Fish & Wildlife Agencies regions in developing, implementing, and evaluating a bridge-building engagement strategy, focused on one population segment or potential partner organization per state. The team will use evaluation results to refine the bridge-builder engagement model, then distill and package tactical recommendations into a set of tools for use by conservation relevancy-related staff and practitioners. Anticipated project outcomes include enhanced staff capacity for building lasting collaborations with unengaged population segments and new partner organizations; increased confidence of agency leadership that their agency has the tools it needs to build collaborations with such populations and organizations; lasting relationships with constituency groups who have not historically engaged with agencies; and increased constituency awareness of, participation in, support for the agency’s role in conservation. Project deliverables will include tactical recommendations presented as a set of practical, accessible tools that can be implemented by staff at any level within an agency, descriptions of processes used during the project, links to resources used during the project, and an evaluation of project outputs and outcomes. The project is designed to provide lasting benefits to the four-or-more participating agencies, the population segments and potential partner organizations engaged during the project, and all state fish and wildlife agencies in need of a reliable methodology for developing new collaborations.
