Perspectives on wildlife health in national parks: concurrence with recent definitions of health.

A Delphi exercise involving 17 senior national parks' biologists in the United States of America and Canada examined how evolving concepts of wildlife health resonated with Parks' needs. Participants examined wildlife health as a multi-factorial cumulative effect that provides capacity to cope with a changing world. They agreed that this concept of health was consistent with Parks' goals and provided insight on various aspects of wildlife health in national parks. Social and environmental determinants of health were perceived to be greater threats to wildlife health than etiological hazards such as pathogens, the more typical focus of wildlife health efforts. While social and anthropogenic factors are primary drivers of these threats, participants did not explicitly rank social variables as the more important drivers of wildlife health nor did the majority view health as a social construct. The results clearly show support for moving toward a contemporary approach of wildlife health management, as opposed to disease management, and for the need of collective, team-based approaches to protecting the suite of determinants of health.
