ABSTRACT
Project in cooperation with U.S. Department of Agriculture, Natural Resources Conservation Service, Indianapolis, Indiana
Wetlands serve many ecological and hydrological functions. The NRCS Wetland Reserve Program planning criteria state for a site to be a wetland eligible for a restoration in agricultural land, it needs be in a zone with sustained or frequent flooding for a period of 7 consecutive days on average at least once every 2 years (a recurrence interval called the 7MQ2).
The objectives of this project are to expand the library of 7QM2 potential wetland extent maps in Indiana; to make existing and new maps in the library available through an on-line public map viewer; to document software for 7QM2 map preparation; and to publish results of field verification of the maps, along with new maps by USGS.

Developing the tools for assessing and mapping marsh (and grassland) canopy structure – Elijah Ramsey III, U.S. Geological Survey
The capability to map marsh structure started with developing field methods that provided quantitative and reproducible 3-dimentional representations of marsh canopy structure. Methods of field collection were standardized over numerous studies and conversion of those standardized field measurements to vertical profiles of leaf area index (LAI) and average leaf angle distribution (LAD) was accomplished without user supplied estimates. LAI integrated to a volume metric and LAD were combined with polarimetric SAR data to create empirical relationships that were then used to create maps of marsh structure.
Hurricane Surge Extent, Persistence and Marsh Condition Change – Amina Rangoonwala, U.S. Geological Survey
Working to support coastal resilience, our studies have focused on providing resource management with effective strategies for identifying latent impacts to coastal resources. Within that effort, we have studied the capabilities of radar to map subcanopy flooding and its persistence in coastal marshes. We have also used optical to show how surge can cause widespread fresh and saline marsh dieback. Here we use a sequence of post landfall radar based surge extents to calculate surge persistence and link that to optical based pre to post landfall marsh live biomass change.

Watershed-scale hydrologic simulation of geographically isolated wetlands: methods and preliminary results - Grey Evenson, PhD, Post-Doctoral Fellow, Virginia Tech and Visiting Scientist, U.S. EPA
Geographically isolated wetlands (GIWs), defined as wetlands surrounded by uplands, provide an array of ecosystem goods and services. Within the United States, federal regulatory protections for GIWs are contingent, in part, on the quantification of their singular or aggregate effects on the hydrological, biological, or chemical integrity of waterways regulated by the Clean Water Act (CWA). However, limited tools are available to assess the downgradient effects of GIWs. We modified the Soil and Water Assessment Tool (SWAT), a popular watershed-scale hydrologic model, to incorporate an improved representation of GIW hydrologic processes and thereby evaluate the watershed-scale hydrologic effects of GIWs on downgradient hydrology. This webinar will review (1) our approach to incorporating National Wetland Inventory (NWI) delineated GIWs into SWAT; (2) our method of re-defining SWAT Hydrologic Response Units (HRUs) boundaries to conform to the boundaries of NWI delineated GIWs while simulating fill-spill inter-GIW hydrologic flows; and (3) preliminary results from the application of our modeling approach in the ~1,700 km2 Pipestem watershed in the Prairie Pothole Region of North Dakota. Our approach to modifying SWAT may be replicated to evaluate the watershed-scale aggregate hydrologic effects of GIWs in different watersheds and physiographic regions.
Integration of remote sensing data into a watershed-scale wetland modeling for an improved model prediction - Sangchul Lee, PhD, Candidate, University of Maryland
Wetlands provide important ecological benefits for biodiversity and water quality. This ecosystem functioning highly relies on the hydrological characteristics of wetlands (e.g., hydro-period) and their connectivity to the downstream waters. Soil and Water Assessment Tool (SWAT), one of widely used watershed models, has been applied to investigate catchment-scale wetland hydrological function. However, uncertainties associated with wetland parameterization and the prediction of inundated areas have not been thoroughly assessed due to the data unavailability. Remote sensing provides synoptic information on the spatial distribution of wetland, and recent studies demonstrated improved capability to characterize wetland inundation patterns at a high resolution (30-m) using time series Landsat records and LiDAR. This study integrated remote sensing data into Soil and Water Assessment Tool (SWAT) to improve the wetland parameterization and prediction on inundated area and to assess the cumulative hydrological impacts of wetlands on the downstream water. We adopted Riparian wetland module (RWM), a SWAT extension for riparian wetlands, to simulate interactions between RWs and nearby streams. We illustrated how inundation maps (derived from satellite remote sensing) can be used to set up spatially varying wetland parameters and to assess predicted inundation at the landscape scales, considering the assumptions and simplification of wetland processes represented in SWAT. Using the Choptank Watershed as a case study, we demonstrated the hydrological benefits of wetlands to stabilize overall flow pattern and reduce peak flow at the storm event.
Role of Prior Converted Croplands on Nitrate Processing in Agricultural Landscapes - Gregory McCarty, PhD, Research Soil Scientist, USDA
Prior converted croplands (PCC) are wetlands that were drained for crop production prior to the Swampbuster provisions of the 1985 Food Security Act. Within the Swampbuster provisions, PCC’s will revert to wetlands if the land is not cropped for five years and as such they hold special status within agricultural ecosystems for conservation. Our research has found that although PCC’s are sufficiently drained for crop production, they still retain some of the biogeochemical characteristics of wetlands because of both intrinsic (soil) and extrinsic (landscape position) properties. We find evidence that the amount of nitrate exported from agricultural watersheds can be related to extent of crop production on hydric soils associated with PCCs. We hypothesize that this relationship is due to increased ability of PCC’s to process nitrate before leaching to groundwater. The SWAT model has now been successfully modified to better reflect the unique role PCC’s play in mitigating nitrate export for agricultural production systems. This work also emphasizes the need to better map the location of PCC’s in agricultural ecosystems both for conservation and for understanding the fate of agricultural nitrogen.

ABSTRACT
Defining Wetland Gems in North Central New Mexico – Amigos Bravos and GeoSpatial Services
In a recent project, Amigos Bravos and the Western Environmental Law Center worked with GeoSpatial Services of Saint Mary’s University to identify important wetlands in the Carson National Forest of North Central New Mexico. This project utilized recently developed landscape level wetland mapping available from the New Mexico Environment Department (NMED), Surface Water Quality Bureau (SWQB). The purpose was to identify and characterize important wetland complexes in order to provide input to the U.S. Forest Service ten-year planning process and to help guide stakeholder opportunities for on-the-ground wetland management and restoration.
In order to facilitate this process, GeoSpatial Services conducted a GIS-based query and analysis exercise that resulted in the identification of key wetlands or wetland complexes within the National Forests that could be targeted for preservation, restoration and/or enhancement. These “Wetland Gems” were defined using a combination of NWI wetland boundaries, LLWW functional assessment criteria, HGM regional sub-classes and a variety of collateral spatial data layers such as SSURGO soils, NHD, cold and warm water fisheries and landcover.
Current efforts are focused on development of a methodology to quantify the total functional performance of a given wetland at three scales: the wetland mapping unit, the spatial context within a larger ecological unit (watershed), and wetland/watershed recovery priorities and management goals at some regional scale (county). While these three scales are qualitatively represented in the current Wetland Gems selection criteria, efforts are now focused on developing a scientifically credible and defensible quantitative approach.

ABSTRACT
The U.S. Fish and Wildlife Service (FWS) started the operational phase of the National Wetlands Inventory (NWI) in 1979 with two main efforts: wetland mapping and wetlands status and trends. After 35 years and more than $220 million, the FWS completed the wetland mapping for the conterminous United States. Using current technology and today’s dollars, it would take approximately $260 million to remap the wetlands in the same geographic area. However, with emerging technologies and access to large amounts of remote sensing data (imagery, Lidar, Radar), there may be ways to drastically reduce the cost for mapping wetlands.
Ducks Unlimited and the Minnesota Department of Natural Resources have been utilizing semi-automated wetland mapping techniques for the Minnesota wetland mapping project. While we have made significant progress in automating some of the wetland mapping, there is still a long ways to go before a more fully automated system is developed. This presentation reviewed our system for semi-automated wetlands mapping and highlight some of the successes and failures. The presentation also looked at the potential for utilizing some of these techniques in future wetlands mapping projects.

ABSTRACT
The Wisconsin Department of Natural Resources and Saint Mary’s University of Minnesota GeoSpatial Services (GSS) have recently started work on a detailed wetland functional assessment of the Marengo River Watershed within the Lake Superior Basin of Northern WI. The Marengo River has been identified as a key watershed for restoration efforts funded through the Great Lakes Restoration Initiative. Infrastructure and strong support for watershed conservation activities exists within the Lake Superior Basin Partnership, the Chequamegon Bay Partnership and the Bad River Watershed. However, some of the detailed current wetland information needed to prioritize wetland restoration and conservation is not available. This project is supplying the information needed to identify restoration opportunities at the parcel level and demonstrate how a functional assessment of existing wetlands can support prioritization of conservation opportunities. This webinar will summarize project activities to date.
Work includes development of a feasibility matrix for evaluating wetland restoration opportunities which defines characteristics for prioritizing and directing investments in wetland restoration activity based on such factors such as: watershed needs, funding, local planning, land ownership, historic and predicted climate patterns, and PRW location. This includes the development of a list of feasibility categories such as ecological, social and economic as well as a method for comparing historic distribution of wetlands (PRW) with current wetland locations dissected by current property ownership. This will permit the compilation of contact lists for distribution of educational materials and the communication of stakeholder engagement opportunities to land owners/wetland locations that have a real opportunity to impact watershed issues. It will also provide government decision makers with data to support planning, zoning and bylaw decisions.

National Wetlands Inventory Version 2 – Surface Waters and Wetlands

PRESENTER

ABSTRACT
The NWI 2.0 dataset is a more comprehensive characterization of all surface water features on the landscape. It stems from the need to represent all surface waters and wetlands as polygons in a single geospatial dataset to facilitate accurate area calculations and provide consistent, standardized ecological classification to allow for adaptive management, geospatial summaries, and modeling. The NWI 2.0 has been created by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections.
Due in part to how wetlands were mapped in the past, coupled with improved geospatial processing techniques, the NWI 2.0 dataset is a departure from the legacy NWI data in several ways. The NWI 2.0 depicts all surface water and wetland features in a single database; it applies the FGDC Classification of Wetlands and Deepwater Habitats (Cowardin et al. (1979), system to provide consistent ecological descriptors intended to address wetlands and water bodies; and it imparts new and improved information about wetland extent and hydrologic connectivity.
There are many opportunities to apply NWI 2.0 data to assist in resource management, planning, and strategic habitat conservation efforts. Applications include various geospatial analyses, tracing contaminant pathways through aquatic systems, identifying and prioritizing habitat restoration opportunities, examining continuity or dissection of habitat corridors, quantifying aquatic and wetland resource types, and facilitating ecological modeling.
