Definition

Wetland restoration is the manipulation of a former or degraded wetland's physical, chemical, or biological characteristics to return its natural functions.1 Restoration practices include:

  • Re-establishment, the rebuilding a former wetland; and
  • Rehabilitation, repairing the functions of a degraded wetland (US EPA, 2007a).

Wetlands protection is defined as removing a threat or preventing the decline of wetland conditions (US EPA, 2007a). 2

Restoration and protection efforts can be either regulatory or voluntary. Regulatory restoration and protection results from federal, state, tribal, or local laws and regulations that prohibit, condition, or compensate for permitted impacts to existing wetlands. Examples include 401 certification, zoning, permitting programs, and mitigation requirements. The Regulatory core element includes actions to develop the regulatory aspects of wetlands restoration and protection. Voluntary restoration and protection refers to activities not required by statutes or regulations. Examples include land trusts purchasing titles or easements to wetland areas, community groups removing invasive species and planting native vegetation, and conservation programs that pay landowners to change practices such as cultivation or grazing that alter wetland areas. While by definition voluntary protection is not required, it can be secured through legally binding agreements, such as conservation easements.

Both regulatory and voluntary wetland restoration play a role in states and tribes broader implementation of Clean Water Act (CWA) and Safe Drinking Water Act programs. For example, CWA Section 319 grants provide funds and technical assistance to state and tribes to develop plans and implement them to promote the reduction of non-point source pollution. Strategic wetland restoration can play an important role in implementation of state and tribal non-point source plans. In some cases, voluntary restoration and protection can strengthen regulatory programs. For example, states and tribes can share maps of vulnerable or rare wetland resources with regulatory programs so that permit applications receive heightened review. They can also suggest areas prioritized for restoration as compensatory mitigation sites.

Whether as a stand-alone effort or as a complement to a state/tribal regulatory program, voluntary restoration and protection efforts help stem the loss and create a gain in natural wetlands and their associated functions. Voluntary restoration and protection is the subject of this core element, with particular focus on restoring or protecting natural wetlands to maintain or attain a high level of overall wetland function/condition. Many states and tribes rely on voluntary restoration and protection activities as a basis for their wetlands programs. Voluntary projects achieve important protections while providing opportunities to build partnerships, share data and pool resources with agency, community, and nonprofit groups. Voluntary projects can provide an excellent opportunity to educate the public about the value of water resources. States and tribes with regulatory programs may choose to supplement these efforts with voluntary restoration and protection activities.

1Council of Environmental Quality, White House Wetlands Working Group Report. 2000.

2The White House Wetlands Working Group (WHWWG) also defines two activities related to but distinct from restoration: establishment (also known as construction or creation): developing a wetland where one did not previously exist; and enhancement: manipulating the physical, chemical, or biological characteristics of an undisturbed or degraded wetland to heighten, intensify, or improve specific functions such as pollution control, flood water retention, and provision of wildlife habitat. This chapter does not address these activities as they do not return a wetlands to its natural functions as defined above. (US EPA, 2007a).

Goals and Benefits

States and tribes enjoy numerous benefits of restoration and protection due to the many functions that natural wetland systems perform. Wetland restoration and protection is important to maintain critical wildlife habitat, help meet state and tribal watershed goals, and contribute to economic well-being. To achieve these goals, a number of States have invested in programs that help implement, support or coordinate local restoration efforts. For example, Natural Heritage programs often rely on state support and work though partnerships to protect wetlands as part of their habitat goals.

Wetlands provide critical habitat, breeding grounds, and sources of food for shellfish, fish, birds, amphibians, and other organisms (US EPA, 2007b, 50-51). More than one-third of the threatened and endangered species in the U.S. live exclusively in wetlands and nearly half use wetlands at some point in their life cycle. Consequently, species recovery plans commonly include targeted wetlands protection and restoration to provide habitat for threatened species. Wetlands play a crucial role in many state and tribal fishing economies. Approximately 70 percent of the nation's $111 billion commercial and recreational fishing industry is generated from wetland-dependent species. Wetlands are also preserved to provide feeding and resting grounds for migratory birds and to create habitat corridors for wildlife populations. These services generate state and tribal commercial, recreational, and aesthetic benefits as well.

Wetlands also control erosion, limit flooding, moderate groundwater levels and base flow, assimilate nutrients, protect drinking water sources, and buffer coastal areas from storm surges (US EPA, 2007b, 50-51). States may pursue wetland restoration to improve water quality and comply with Total Maximum Daily Load (TMDL) pollutant allocations in impaired waters and watersheds. Researchers are studying the rate at which different types of wetlands can store nutrients, sediment, and carbon, as well as any unintended consequences of using wetlands to perform these services. Some programs are restoring wetlands to store floodwaters and reduce the height of peak river flows. Many coastal communities are evaluating their wetlands' ability to absorb storm surges and the potential for wetlands protection and restoration to reduce hurricane damage. These actions illustrate how that wetland restoration and protection can play an important role in helping states and tribes adapt to changing weather patterns potentially including future impacts of global climate change.

It is important to recognize that an accurate and up-to-date inventory of wetlands is very valuable when embarking on a restoration program. If comprehensive data is not available, a program can start with available maps and data and expand from there.

States and tribes can pursue any or all of the following objectives as they develop voluntary restoration and protection efforts:

  1. Clearly and consistently define restoration and protection goals throughout state or tribal territory;
  2. Protect wetlands from degradation or destruction;
  3. Restore wetland acres, condition, and function; and
  4. Track progress over time, document results, and modify practices as appropriate.

Program Building Activities Menu

Most of these program building activities will be relevant and should be linked to existing watershed plans (both quantity and quality focused) and critical environmental area plans. States and tribes can carry out the following actions and measures of progress to achieve their restoration and protection objectives.

Objective 1: Clearly and consistently define restoration and protection goals throughout state or tribal territory.

Actions Menu of Activities
  1. Establish goals that are consistent or compatible across relevant agencies
  • Coordinate with relevant agencies that outline restoration/protection goals and strategies and timeframes
  • Develop multi-agency body to coordinate restoration/ protection efforts
  • Gather information on wetland location, class and condition/functions
  • Set restoration goals based on agency objectives and available information .
  1. Consider watershed planning, wildlife habitat, and other objectives when selecting restoration/ protection sites
  • Identify rare, vulnerable, or important wetlands and prioritize for restoration/protection
