Since 1948, the Wildlife Management Institute (WMI) has compiled information on fish and wildlife agency organizational structures, their authorities, and their priority program areas about once every 10 years. The information provided a once-a-decade snapshot of how North American fish and wildlife agencies were shaped – and how they shaped the conservation landscape. Societal changes and their impacts on fish, wildlife, and habitats – and conservation agencies – are quickening. The diversity of agency responsibilities, authorities, and programs is evolving – and agencies and stakeholders need timely information to aid in local, regional, and national program and policy decisions.
