Wetland Restoration: Contemporary Issues and Lessons Learned (August 2017)
There is general agreement among restoration professionals that the science exists to achieve restoration goals and that wetland restoration performance will improve if certain barriers are addressed. Many lessons have been learned over the past 50 years and there are wetland professionals throughout the country who have found methods to effectively address these barriers. However, much of this information is stored in the minds of those who have learned these lessons over time. Our intent with this paper is to disseminate this information, provide guidance for improving restoration outcomes and to identify practical solutions for those who can implement them. This white paper was developed with guidance from a national expert work group in order to disseminate this information, present potential solutions to restoration challenges and barriers, and recommend specific actions that can be taken to improve wetland restoration outcomes.

ASWM Wetland Communications Case Studies Project Report (August 2017)

Ten case studies were selected, representing a range of geographic locations, target audiences, messaging goals, tools used and level of development. Each case study provides information on project need and context, timeframe, goals and objectives, target audience, messages, delivery approach, specific communication tools employed, advice/lessons learned, next steps, transferability, resource investment, partners, evaluation results and case study contact information.

New Features and Publications Challenges & Solutions in Coastal Wetlands: Findings, Gaps & Priorities (October 2016)
This white paper is divided into three topic areas addressing major threats to coastal wildlife. The three subject matter areas include: (1) wetland protection and management; (2) wetland restoration; and (3) natural coastal defenses. This paper is the final product of a one-year grant from the U.S. Fish & Wildlife Service Coastal Program and is intended to identify gaps and priorities that can be addressed in future years by the Association of State Wetland Managers and other organizations. 

Governmental Liability and Climate Change: Selected Issues for Wetland and Floodplain Managers (April 2016)
Governments may increase flood damages by failing to anticipate climate change (e.g., failing to elevate houses) in their programs and policies. This paper by Dr. Jon Kusler, Esq. is one of several designed to help government wetland and floodplain managers understand their potential legal liability for failing to consider climate change in their programs or for incorporating strengthened flood loss reduction standards reflecting climate change in their zoning, building codes, subdivision and other regulations. 

Legal Issues in Upgrading Flood Maps to Reflect Climate Change, Other Changed Conditions (April 2016)
Governments will, over time, need to upgrade flood hazard maps to reflect climate change, urbanization, erosion and sedimentation and other watershed changes. Will governments face legal problems with such upgrading? How can governments avoid legal problems? This paper by Dr. Jon Kusler, Esq. provides an overview of the types, uses and limitations of existing floodplain maps, examples of court cases dealing with floodplain maps and recommendations for avoiding problems with upgrading floodplain maps to reflect climate change and other changed conditions. 

Definition of Wetland, Floodplain, Riparian “Functions” and “Values” (April 2016)
State and federal wetland regulatory programs typically include an overall goal to prevent net loss of wetland “functions”, and “values”. However, there is only partial agreement among regulators and other wetland managers concerning the use of these terms. This paper explores the use of the terms “function” and “value” and makes suggestions for future use of these terms.

A Comparative Analysis of Ecosystem Service Valuation Decision Support Tools for Wetland Restoration (March 2016)
The Association of State Wetland Managers (ASWM) published a report in 2014 on the valuation of ecosystem services as an advantageous method for the promotion of wetland restoration. As a continuation to this effort, in 2015 we conducted an extensive review of existing decision support tools suitable for the valuation of ecosystem services for wetland restoration. This report describes six tools that maintain “off-the-shelf” capability and currently demonstrate the greatest potential for widespread dissemination and use.  

Protecting and Restoring Riparian Areas (March 2016)
This paper briefly examines the functions and values of “riparian” areas. It suggests some priority measures states, local governments, federal agencies, and not for profit organizations can take to better protect and restore riparian areas.

Model “Riparian” Protection Ordinance (March 2016)
The model ordinance provided in this paper is designed to help local communities develop their own “riparian” ordinance and has been prepared as a “stand alone” ordinance. However critical provisions could be extracted for inclusion in broader ordinances. 

Status and Trends Report on State Wetland Programs in the United States (October 2015)
ASWM’s national study was designed to: 1) assess status and trends; 2) identify models and lessons learned; and 3) document information and program development needs. Information gathered for each state includes a focus on status of programmatic elements, focusing on EPA’s Core Elements Framework. In addition to the report, a clickable map on ASWM’s Wetland Program Webpage allows users to access individual state summaries for each of the 50 states. 

Wetlands and Climate Change: Considerations for Wetland Program Managers (July 2015)
This paper explores the relationships between wetland management and climate mitigation and adaptation. These relationships are divided into three categories: the impacts of climate change on wetland ecosystems; the role of wetlands in mitigating the impact of climate change; and the role of wetlands in supporting adaptation to climate change impacts. 

Uses of Monitoring and Assessment: Considerations for State and Tribal Programs (June 2015)
This report explores the various ways that states and tribes could make better use of existing monitoring and assessment methods to obtain science-based answers to wetland management problems. While it provides an overview of many common approaches to wetland monitoring, the focus is primarily on why these methods are selected for a given purpose. 

Report on State Definitions, Jurisdiction and Mitigation Requirements in State Programs for Ephemeral, Intermittent and Perennial Streams in the United States (April 2014)
This report discusses the findings from ASWM’s national study on stream identification, delineation and mitigation in the United States. The project interviewed state staff from 47 states and provides both a comparative analysis and information on individual states.   

Ecosystem Service Valuation for Wetland Restoration: What It Is, How To Do It and Best Practice Recommendations (2014)
This paper is intended to assist those interested in using ecosystem service valuation to promote wetland restoration by: explaining what ecosystem service valuation is; framing it within the history of wetland science and policy; identifying available methods and tools; offering examples of use through case studies of watershed and/or wetland restoration projects that have utilized ecosystem service valuation; and providing recommendations for using ecosystem service valuation within the context of wetland restoration.
