Bringing together a diverse set of stakeholders (including "states and tribes, federal agencies, nonprofit partners, wetland professionals, educators, wetland enthusiasts and many others,"), the Association of State Wetland Managers exists to study and sustain wetlands. The site has a variety of materials, from Publications such as the Wetland News Digest (a monthly compilation of wetland stories, policy updates, and relevant resources) to Law & Policy briefs explaining key regulations such as the Clean Water Act. Readers new to wetland conservation and management will want to explore the various sections of the Science tab, which provide primers on topics such as hydrology, invasive species, and watersheds. The Wetland Programs tab is dedicated to various aspects of the EPA's Core Elements Framework ("a menu of activities that states and tribes can draw from to design their own roadmap towards a more comprehensive wetland program,"). Users should note that most materials on the site are open-access, but a few are limited to members (and require a log-in).
