Take the new wetlands survey 
Current Projects:
-
Missouri Wetlands Monitoring and Assessment: This project aims to develop a physical wetlands monitoring pilot program in partnership with the Department of Civil and Environmental Engineering of the University of Missouri. The Water Resources Center will install instruments at diverse sites across the state to record data by satellite telemetry. Water levels and meteorological data will be collected remotely to help increase the knowledge and understanding of Missouri wetland systems. University staff will conduct chemical and microbiological studies at the selected sites to better understand the relationship between water levels and soil conditions. This project began in April 2008 and will conclude in April 2011. The U.S. Environmental Protection Agency, Region 7, the Missouri Department of Natural Resources, and the University of Missouri are funding this project.
-
Wetland Nutrient Monitoring and Biologically Based Nutrient Enrichment Assessment: This project aims to demonstrate a wetlands nutrient monitoring program in Missouri and develop biologically based nutrient enrichment assessment tools that can then be used to assess the health of wetland ecosystems. Selected wetland monitoring sites will be monitored to determine seasonal changes and spatial distributions of nutrients in wetland soils. The results of this project will help to improve Missouri’s wetland monitoring, water quality decision making, and help to protect and restore biological conditions in wetlands. The Water Resources Center and the Department of Civil and Environmental Engineering of the University of Missouri will continue their partnership, and use this project to complement and enhance efforts of the Missouri Wetlands Monitoring and Assessment project. This project began in November 2008 and will conclude in September 2011. The U.S. Environmental Protection Agency, Region 7, the Missouri Department of Natural Resources, and the University of Missouri are funding this project.

Establishing a Dollar Value for Wetlands: This project aims to establish a current dollar value for wetlands under past, present and future conditions. The valuations or appraisals will be based on a per-acre basis as a common geographic measure. Besides helping to mitigate wetlands loses, innovative ideas such as actual dollar for dollar exchanges and future wetland tax credits will be explored.

Urban Wetlands Grant: The East Fork Little Blue River and the Rock Creek watersheds were chosen to assess the impact of urbanization to wetlands. Both study areas were chosen due to their population growth, presence of wetlands on the National Wetland Inventory (NWI), and access to wetlands on public lands. The NWI was used as baseline data by which comparisons were made from color infrared aerial photography that was acquired in 2002. Photographic interpretations were performed to determine the amount of wetlands that still exist, and land use conversions of those that have been eliminated.
Water quality was collected on a quarterly basis in both watersheds at sites selected using a stratified random sampling design. Parameters chosen for analyses were: total phosphorous, pH, dissolved oxygen, conductivity, nitrate, nitrite, ammonia nitrate, and temperature. Analysis was conducted using a Hach DR 2000 and EPA approved methods.
Soil was analyzed for copper, lead, zinc, and nickel at each wetland site in the spring of 2002.
A plant survey was also conducted at the sites chosen for water quality sampling. Throughout the term of the project, plants were identified within a 1.5 meter plot at each site.
The U.S. Environmental Protection Agency, Region 7, made funding for the Urban Wetlands Grant possible. The complete project is found here. Final Report 1.07 MB PDF

Wetland Image Analysis Grant: The goal of this study is to develop a "cook-book" for using remote sensing (satellite imagery, aerial photography) to identify specific types of wetlands. Study sites are located on public lands such as the Missouri Department of Conservation refuge areas, Department of Natural Resources state parks, or Fish and Wildlife Service refuges. Cooperation with these agencies is essential for the success of this project. These areas are all located in close proximity to the Missouri River. Other state and local agencies and wetland professionals who are interested in a cost-effective method of collecting large-scale wetland data may use the results of this study. Results may also be used in the future for a comprehensive wetland inventory for Missouri. This was completed in July 2002. Final Report PDF

Assessment of Section 404 Wetland Mitigation Sites in Missouri: Assessment of specific wetland mitigation sites representative of Section 404 wetland mitigation efforts in Missouri was conducted. Existing conditions of the sample sites were compared to those intended as described in the individual Section 404 Wetland Mitigation Plans. Findings of the assessment will contribute to the effectiveness of compensatory mitigation for wetlands. Final Report 2.9 MB PDF
- Wetland Hydrology Grant: The purpose of this study is to develop and refine methodology for determining the flooding regimes of Missouri riparian wetlands. The study objectives are to correlate the area inundated by a flood of a given magnitude and the boundaries of a wetland, estimate the frequency a wetland is inundated, estimate the duration that a wetland is inundated and refine methodology to be applied on a regional or watershed basis. This was completed in July 2001. Final Report 2.31 MB PDF
