Hydric Soils Online Training Series
Module 5: Hydric Soil Processes - Hydric Soils Functions
The module focuses on wetland functions attributed directly to hydric soils. Functions are the biological, chemical, and physical processes that occur in wetlands. Hydric soils play a direct role in the wetland functions of water retention (short term and long term), sedimentation, carbon sequestration and biogeochemical cycling of nutrients. Due to their capacity to become anaerobic close to the surface, hydric soils support unique plant communities and wildlife habitat unlikely to be found in uplands. Functional capacity is influenced by landscape position, hydrologic characteristics, and soil characteristics. Soil characteristics that affect wetland functions include porosity, permeability, drainage class/hydroperiod, organic matter content, slope, micro-topography, and chemical properties.
Wetland field practitioners who need expertise in hydric soils and seek to understand how hydric soils are formed and how to recognize and interpret the information they provide when observed in the field.
Module Learning Objectives
By taking part in this online training, participants should be able to:
- Identify the basic biological, chemical and physical processes attributed directly to hydric soils that provide wetland functions;
- Understand how hydric soils play a direct role in the wetland functions of water retention (short term and long term), sedimentation, carbon sequestration and biogeochemical cycling of nutrients;
- nderstand that hydric soils support unique plant communities and wildlife habitat unlikely to be found in uplands due to their capacity to become anaerobic close to the surface;
- nderstand that functional capacity is influenced by landscape position, hydrologic characteristics, and soil characteristics.
- dentify soil characteristics that affect wetland functions, including porosity, permeability, drainage class/hydroperiod, organic matter content, slope, micro-topography, and chemical properties.
Bruce Vasilas, PhD, is a Professor of Agronomy and Soil Management in the Plant and Soil Sciences Department at the University of Delaware. His research focuses on hydric soils and wetlands ecology, identification, morphology and interpretation of hydric soils, water quality in wetlands, functional assessment of wetlands, monitoring of wetlands for hydrology and biogeochemical cycling, and other wetland and water related areas. Bruce serves on the Mid-Atlantic Hydric Soils Committee, Soil Science Society of America, Society of Wetlands Scientists, and American Society of Agronomy. Bruce received his Ph.D.in Soil Microbiology from the University of Minnesota; and his M.S. in Soil Biochemistry from the University of Maryland.
Link to Online Quiz
To complete this module, use the following link to access the module quiz on ClassMarker. Once you complete and submit the quiz, it will be automatically graded and you will receive your quiz score and the correct answers. Passing the quiz will also qualify participants to download a Certificate of Completion that the participant can submit themselves to accrediting organizations for continuing education credits.
To Take the Quiz and Receive a Certificates of Completion for this Module
Participants who both view the module presentation and complete the module quiz are eligible for an ASWM Certificate of Completion for 0.5 hours of training.
Using the ClassMarker online system, ASWM will ask you to certify that you completed viewing the entire hydric soils training module video presentation.
You will need to develop a username and password in ClassMarker. Once you click on the quiz link, you will be prompted again to provide your name and email address, which will be used to process your certificate.
To receive your certificate you must BOTH:
- Certify that you completed viewing of the video presentation. Answering “no” will result in no certificate being issued.
- Complete all 5 quiz questions, getting three or more of the questions correct. You will be provided three attempts to take the quiz for the module. If at the end of your third attempt you have not been able to get three or more correct, you will not be eligible to receive a certificate.
You will be prompted to download your Certificate of Participation from ClassMarker after you complete the quiz.
Once you download your certificate, you can then submit the certificate to the accrediting organization of your choice to potentially receive continuing education units/credits.
