Surveys of the Nation’s Waters • Statistically valid surveys – history • National Coastal Assessment 2000-2006 • Wadeable Streams Assessment 2004-2005 • Survey Schedule 2007 – Lakes 2010 - Coastal 2008 – Rivers 2011 - Wetlands 2009 – Streams 2012 – Lakes • EPA Office of Water • Implement through state §106 Grants
Survey of the Nation’s Lakes • What percent of the Nation’s lakes are in good, fair, and poor condition for key indicators of trophic state, ecological health, and recreation? • What is the relative importance of key stressors such as nutrients and pathogens? • Lakes > 10 acres and ≥ 1 m • 5 size classes in 48 states • 909 lakes • Indicators • Trophic (water quality) • Ecological Integrity • Biota • Habitat • Recreational (pathogens)
National Wetlands Condition Assessment • EPA will collaborate with State and Tribal partners to refine the three objectives of the National Wetlands Condition Assessment: • Produce a national report that describes the quality of the nation’s wetlands, • Build State and Tribal capacity to implement wetland monitoring and assessment programs that will guide policy development and aid project decision-making, • Advance the science needed to achieve Obj. #2.
Collaboration with FWS • EPA will collaborate with FWS in designing NWCA • ensure the national condition assessment most effectively complements the Service’s Wetlands Status and Trends Study. • NWI Status and Trends documents trends in wetlands acreage • NWCA will evaluate the ambient condition of the nation’s wetlands resources. • Together these reports will offer the most comprehensive ecological evaluation of the nation’s wetlands to date and provide valuable information to support policy and resource management decisions.
National Wetlands Monitoring & Assessment Workgoup Communications with Other States/Tribes • State/Tribal Program Implementation Team • Monthly Meetings • EPA and State/Tribal Reps • Building State Program Capacity • Wetlands Mapping • Regulatory Support and Methods Development • Assessment Advisory • Team • Meetings TBD • EPA, State/Tribal, Federal Reps • Responsive to EMAP Team and OWOW • Input on specific issues related to the national condition assessment • Steering Committee • Meetings as needed • EPA HQ and Regions
NWMAWG • States/Tribes/EPA • Build state and tribal wetland monitoring programs • Foster information exchange and technology transfer • Data management and comparability • Improve wetlands mapping • Sustainable financing • Promote use of wetland assessment data to inform decision-making • Wetlands restoration in a watershed context • Compensatory mitigation performance standards • Inform CWA 401 certification decisions • Wetlands-specific water quality standards
EMAP Wetlands Team • Provide technical guidance to NWMAWG for National Wetlands Condition Assessment • Develop Sample Frame • Recommend Survey Design Options • Recommend Indicators & Methods • Assist with data mgmt, analysis, and reporting • Members • EPA ORD and OW • USGS, USFWS
Progress to DateNational Wetlands Condition Assessment • Target Population • All wetlands of the U.S. – tidal and non-tidal wetted areas with rooted vegetation • Sample Frame • NWI S&T sample plots (4682 2x2 sq. mi. plots), supplemented with new plots in the Pacific coast, including only polygons classified as follows:
Wetland Classes in NWCA • M2 – Marine Intertidal • E2EM – Estuarine Intertidal Emergents • E2SS – Estuarine Intertidal Forested/Shrub • E2AB – Estuarine Intertidal Aquatic Bed • PFO – Palustrine Forested • PSS – Palustrine Scrub/Shrub • PEM – Palustrine Emergents • PAB – Palustrine Aquatic Bed • ?Pf – Palustrine farmed
GOM Coastal Wetlands Pilot Survey • Objectives • Evaluate feasibility of implementing probability survey design on regional scale • Evaluate feasibility of indicators across multiple wetland types • Assess condition of GOM coastal wetlands
Progress to Date • Target Population • All wetlands within GOM coastal boundary defined as all 8-digit HUCs that touch the coast, modified by NOAA EDAs where needed • Sample Frame • All NWI S&T plots within GOM coastal boundary, including the following wetland classes • Estuarine Intertidal Emergents & Forested/Shrub • Palustrine Emergents, Shrub, Forested & Farmed
Assessment Levels • Level 1 – Landscape Assessment • GIS, remote sensing • Wetland coverage, land use • Level 2 – Rapid Assessment • On-site field survey - visual • Scores, metrics • Level 3 – Intensive Assessment • On-site sample collection • Vegetation, water, soils Application of Elements of a State Water Monitoring and Assessment Program For Wetlands http://www.epa.gov/owow/wetlands/monitor/#elements
NMN & Wetlands • NMN design – wetlands deferred • Recognized importance of assessing wetland quality, not just extent • Few states monitor wetland quality but methods are evolving • Plan to add surveys of wetland quality to NMN
