Assessing Wetland Ecological Condition In The Cuyahoga River Watershed., Siobhan Fennessy, J. J. Mack, E. Deimeke, M. T. Sullivan, J. Bishop, M. Cohen, M. Micacchion, M. Knapp

We used an assessment approach combining the USEPA EMAP probabilistic sampling design with existing Ohio wetland assessment tools, including the Ohio rapid assessment method (ORAM), the modified Penn State Stressor Checklist, the Vegetation IBI and the Amphibian IBI, along with a landscape analysis (the Landscape Development Intensity Index) to evaluate the ecological condition of wetlands in the 1,300 km2 Cuyahoga River watershed. Sample sites were selected using the Generalized Random Tesselation Stratified (GRTS) survey design, which provides a geospatially balanced, stratified random sample. The Ohio Wetland Inventory was used as the sample frame for the population of wetlands in the …


Standardized Monitoring Protocols And Performance Standards For Wetland Creation, Enhancement And Restoration, Siobhan Fennessy Dec 2016

Standardized Monitoring Protocols And Performance Standards For Wetland Creation, Enhancement And Restoration, Siobhan Fennessy

Siobhan Fennessy

A condition-based approach to assessing functional replacement for wetland mitigation has been developed using a reference wetland data set of natural wetlands that includes data from the major wetland types that span a gradient of human disturbance. From this data set wetland program tools were developed 1) multimetric biological indices (IBIs) and hydrological and biogeochemical indicators; 2) a rapid (conditionbased) wetland assessment tool (Ohio Rapid Assessment Method for Wetlands); and 3) a wetland classification scheme based on landscape position and dominant vegetation that accounts for variability in ecosystem processes (functions) and ecological services (values) of different types of natural wetlands. …

Biogeochemical And Hydrological Investigations Of Natural And Mitigation Wetlands., Siobhan Fennessy Dec 2016

Biogeochemical And Hydrological Investigations Of Natural And Mitigation Wetlands., Siobhan Fennessy

Siobhan Fennessy

We performed a comprehensive investigation of the biota (structure) and biogeochemical cycles (processes or functions) of a population of natural (n = 9) and mitigation wetlands (n = 10). Intensive data were collected on various wetland ecosystem components including: hydrology, soil and water chemistry, characteristics of the plant, macroinvertebrate and amphibian communities, biomass production, decomposition, and nutrient cycles. The goals of the project were as follows: 1) to demonstrate the efficacy of floral and faunal community-based indicators in order to assess the performance of mitigation wetlands, 2) determine the links between floral and faunal community structural attributes and ecosystem processes …

Testing The Floristic Quality Assessment Index As An Indicator Of Wetland Condition, Siobhan Fennessy, Ricardo D. Lopez

Siobhan Fennessy

Biological indicators of ecosystem integrity are increasingly being sought for use in ecosystem ashessment and goal-setting for restoration projects. We tested the effectiveness of a plant community-based bioassessment tool. the floristic quality assessment index (FQAI) in 20 depressional wetlands in Ohio, USA. A priori. the 20 depressional wetlands were classified by type and ranked to form a disturbance gradient according to the local landscape condition. Ranks were based on surrounding land~cover characteristics. vegetated buffer characteristics. and the extent of human-induced hydrologic alteration at the wetland site. The index was negatively correlated with the disturbance rank of a wetland and with …


Methods For Evaluating Wetland Condition: Using Vegetation To Assess Environmental Conditions In Wetlands, Siobhan Fennessy May 2016

Methods For Evaluating Wetland Condition: Using Vegetation To Assess Environmental Conditions In Wetlands, Siobhan Fennessy

Siobhan Fennessy

In 1999, the U.S. Environmental Protection Agency (EPA) began work on this series of reports entitled Methods for Evaluating Wetland Condition. The purpose of these reports is to help States and Tribes develop methods to evaluate (1) the overall ecological condition of wetlands using biological assessments and (2) nutrient enrichment of wetlands, which is one of the primary stressors damaging wetlands in many parts of the country. This information is intended to serve as a starting point for States and Tribes to eventually establish biological and nutrient water quality criteria specifically refined for wetland waterbodies. This purpose was to be …
