Rewilders are not members of unions. Professional associations offer useful resources such as membership, networking events, training opportunities, and certification. Major environmental associations include the Academy of Board Certified Environmental Professionals, Ecological Society of America, Forest Stewards Guild, National Association of Environmental Professionals, Society for Ecological Restoration, Society of American Foresters, and the Society for Range Management. There are also organizations that focus specifically on rewilding such as Rewilding Institute and the True Nature Foundation.
