Association of State Wetland Managers, Inc.

EIN: 03-0303870


The mission of NAWM is to build capacity for state and tribal members and foster collaboration among the wetland community of practice by encouraging the application of sound science to wetland management and policy, promoting the protection and restoration of wetlands and related aquatic resources, and providing training and education for members and the general public.

Notes from the nonprofit

In 2022, as a result of NAWM’s strategic planning process, we decided to change our name from The Association of State Wetland Managers, Inc. to the National Association of Wetland Managers (NAWM). The intention behind the change was to let our community of practice (which includes not only states, but also Tribes, local agencies, federal agencies, private consultants, non-profits, universities, and more), know that everyone has a seat at our table, in particular our Tribal colleagues. The Association’s membership was polled regarding the potential name change and responded with overwhelming support (90%). NAWM continues to robustly support state and Tribal wetland programs and be a voice for state and Tribal wetland programs in federal policy decisions and elsewhere. However, our impact is greatly magnified by providing a framework for all wetland managers to collaborate, learn from each other, and improve our collective efforts to protect and restore our nation's wetlands.

What we aim to solve

SOURCE: Self-reported by organization

Wetlands provide many important benefits for people including clean water, flood and storm surge protection, groundwater storage, biodiversity for better crop production, commercial seafood production and outdoor recreational opportunities. Wetlands also provide critical habitat for waterfowl, certain mammals and amphibians, reptiles, aquatic insects, fish and birds. However, wetland managers face a number of challenges in protecting our critical wetland resources, including: sprawl and development pressure; conversion of wetlands into use for intensive agricultural production; confusing Supreme Court cases and legal battles; climate change impacts; invasive species; and a general lack of understanding about the value of wetlands and the benefits they provide for our families and our communities. This is not just a regional or national issue of importance - it is a global issue.

Charting impact

Four powerful questions that require reflection about what really matters - results.

• Help states and Tribes develop and implement wetland regulatory and management programs.
• Improve the coordination of wetland programs and policies at all levels of government.
• Provide training and capacity building for state and tribal wetland programs.
• Facilitate the integration of wetlands into water resources and watershed management.
• Build conservation and restoration partnerships among states, tribes, local governments, nonprofits, and other
interested parties.
• Translate wetland science into fair and reasonable government policies.
• Encourage minority participation in wetland protection, restoration, and management.
• Integrate wetlands into broader landscape and resource management initiatives.

1) Identify priority needs for wetland research and applied science.
2) Conduct research and studies and publish results online.
3) Encourage the exchange of information among wetland scientists, managers, and policy makers.
5) Conduct open forums, workshops, webinars, conference calls, discussion boards and symposia.
6) Coordinate policy discussions with other state and professional associations/organizations.
7) Provide direct technical assistance to states, tribes and others requesting our assistance.
8) Analyze the implications of proposed policy changes on wetland resources from a variety of perspectives to assist and inform decision-makers.
9) Actively pursue partnerships with federal agencies, tribes, states, nonprofit organizations, the regulated community and other organizations and interest groups.
10) Increase the availability of wetland information, including providing online learning opportunities such as webinars, online training, forums and other opportunities for interested parties to share information and discuss solutions to current issues.

NAWM currently has a staff of ten. Marla Stelk, the Executive Director, is a highly qualified wetland professional with over 30 years of experience working on wetland, water, and wildlife issues, policy and research, land use planning, outreach, and leadership. Donna Downing, JD, LL.M, Esq., Senior Legal Policy Advisor, has 40+ years’ experience, was formerly the Jurisdiction Team Leader in EPA’s Office of Wetlands, Oceans, and Watersheds and has been an adjunct professor at George Washington University Law School since 1996. Jeff Lapp, Senior Science Policy Advisor, formerly EPA Region III Associate Director for the Office of Environmental Programs, has 32+ years of technical and policy experience in wetland restoration and mitigation, delineation, regulatory policy and enforcement, and senior level management. Portia Osborne, Project Manager, has 10+ years’ experience, formerly as an environmental consultant, with detailed knowledge of state and federal regulations, technical report writing and review, and conducting environmental assessments. Ian Grosfelt, Environmental Analyst, has 10+ years of experience in facilitation and environmental education, program management for environmental nonprofits, sustainable agriculture, and is trained in data analysis and geospatial mapping.

Sharon Weaver, Webmaster, has managed NAWM’s website and publications for 33 years. She publishes NAWM’s monthly ezine Wetland News Digest, weekly Insider’s Edition, and updates NAWM’s website daily. Laura Burchill, NAWM’s Office Manager for over 19 years, has extensive experience organizing conferences, workshops and providing logistical support for webinars, correspondence, membership outreach and more. Dawn Smith, NAWM’s Communications Specialist since 2012, handles all NAWM’s social media communications, external communications schedule and activities, and post-processes NAWM’s recorded webinars. Marti Northover, Accounting & HR Manager since 2018, manages NAWM’s accounting systems, oversees payables and receivables, staff payroll, staff benefits and personnel policies, and ensures all budgets and required financial reports are up to date and submitted on time. Justin Farino, Administrative Assistant, supports NAWM’s membership program, updates NAWM’s state agency contacts list, and collects weekly wetland news stories for sharing.

Collectively, NAWM staff form a cohesive team undertaking a wide variety of successful projects to build the capacity of state and tribal wetland programs to manage wetlands. NAWM’s greatest strength is its ability to develop and facilitate national expert workgroups that bring a level of expertise to NAWM’s projects that has been critical to NAWM’s success for over 40 years. NAWM staff contribute their expertise to collect, organize, analyze, and communicate workgroup findings to make them accessible and transferable.

Since 1983, the primary goal of NAWM has been to help states and Tribes build effective wetland programs. Over the years, NAWM has held multiple meetings and workshops, and published numerous reports relative to wetland science, legal issues and development of wetland programs. NAWM has added to these activities by leveraging online tools to develop a website with extensive information on how to develop and implement wetland programs and by hosting and recording multiple monthly webinars on diverse topics relevant to the development of wetland programs and the restoration, protection and conservation of wetlands and related aquatic resources.

For more than 40 years, NAWM has developed extensive knowledge and expertise about state and Tribal wetland programs that is unique. As such, state and Tribal wetland staff across the country rely on NAWM for policy and technical support. NAWM has repeatedly demonstrated the ability to provide timely, useful information to wetland managers as well as other organizations. In the past decade, NAWM has written a number of reports and legal analyses and has also held workshops on the impacts that the Sackett v EPA Supreme Court decision his having on state and Tribal wetland programs. In recent years, NAWM has issued reports and developed web pages to support development of local wetland ordinances, wetland water quality standards, wetland program plans, §404 assumption, §401 certification and permitting of voluntary wetland restoration projects.

In addition, NAWM maintains contact lists for broader communities of wetland professionals and maintains a robust communications and outreach strategy. In total, ASWM’s contacts include over 18,850 professionals, including state and Tribal wetland managers and those they work with, such as the EPA, Corps, U.S. Fish & Wildlife Service, consultants, nonprofits, academics, tribes, local government and more.

NAWM continues to identify pressing needs, information gaps and opportunities to improve wetland programs and wetland health nationwide. New initiatives include better integration of wetlands into hazard management programs, water quality programs (nutrient and emerging contaminants removal) and environmental markets (water quality trading, mitigation crediting, carbon credits, etc.)

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
