The use of models by ecologists and environmental managers, to inform management decision-making, has grown exponentially in the past 50 years. Due logistical, economical, theoretical benefits, model users frequently transfer preexisting new sites where data are scarce. Modelers have made significant progress understanding how improve generalizability during development. However, always imperfect representations systems constrained contextual frameworks used their Thus, need better ways evaluate possibility unintentional misapplication when transferring sites. We propose a method describing model's application niche for selection process. Using this method, synthesize information from databases, studies, and/or transfers create performance curves heat maps. demonstrated using an empirical developed predict ecological condition plant communities riverine wetlands Appalachian Highland physiographic region, U.S.A. assessed transferability across (1) contiguous U.S.A., (2) wetland types (3) With methodology discussion its critical steps, we set stage further inquiries into development consistent transparent practices model.
