Book Description
In June 2012, a new version of the National Wetland Plant List was released. Changes were made to the definitions of the indicator status ratings, and each species was rated based on its wetland status within ecological regions, three of which occur in Minnesota. Plant Indicators of Minnesota Wetlands provides an up-to-date reference to the new wetland indicator status ratings for much of the state's flora. Part I * Annotated listing of Minnesota's wetland and aquatic plants, arranged alphabetically by family. * Wetland indicator status within each of the three regions present in Minnesota. * Habitat data and county-level distribution maps for nearly all of Minnesota's wetland and aquatic species. * Species of conservation concern in Minnesota. Part II * A to Z list of plants on the National Wetland Plant List that occur in Minnesota, with their status and presence or absence in the three regions of Minnesota.

Book Description
The U.S. Environmental Protection Agency has mandated that states must include the use of biological assessments in their water quality laws to assess the biological integrity of aquatic systems. The Floristic Quality Assessment Index (FQAI), which uses wetland vegetation to assess the biological integrity of an ecosystem, has not been tested in Mississippi. The purpose of this study was to test the efficiency of the FQAI in wetlands along a gradient of human influence. Coefficients of conservatism (CC) were assigned to plant species based on their tolerance to disturbance and fidelity to habitat. A negative correlation was found between the FQAI and level of human disturbance for 53 sites surveyed in the summer of 2004. Based on the results of this study, the FQAI and the average CC could be effective tools for monitoring wetland management and restoration and for identifying areas of high conservation value in Mississippi.

Book Description
In order to combat the loss of valuable wetland functions and services, federal, state and tribal governments must have the tools to accurately assess and monitor the condition of wetland ecosystems. One particular method of wetland assessment is Floristic Quality Assessment (FQA), which has been growing in popularity throughout the United States since its creation in the 1970s. FQA relies on vegetative indicators of human disturbance to assess the integrity of an ecosystem. FQA calculations are based on Coefficients of Conservatism (C-scores), professionally-assigned scores ranging from 0-10 that denote a local species' tolerance to anthropogenic disturbance. Despite increasing interest in the use of FQA, few studies have thoroughly tested the performance of FQA, especially in New England. We used the Conservation Assessment and Prioritization System (CAPS), a landscape-based, coarse-scale assessment method, as a basis for evaluating FQA's performance in Massachusetts's forested wetlands. Our objective was to use CAPS Index of Ecological Integrity (IEI) scores (a form of generalized stressor gradient) to evaluate the performance of a variety of FQA indices (biological condition gradients), using C-scores from 7 states in the Northeast, and 2 ecoregions in Massachusetts. Based on our calculations of r-squared, and Spearman's rank analysis, we determined that FQA and C-scores have a moderate to weak relationship with the CAPS index of ecological integrity. Of the 12 indices and metrics we tested, the index with the strongest relationship to the IEI stressor gradient was mean Coefficient of Conservatism. Based on this research a number of suggestions are proposed for improving FQA as it applies to wetland assessment.

Book Description
Wetland Plants of Minnesota is a comprehensive field guide to the vascular plants of Minnesota's wetlands, including plants of bogs, fens, swamps, marshes, wet meadows, and low prairie, plus the aquatic plants of lakes, ponds, rivers, and streams. Fully illustrated with line drawings and many photographs, the book is an essential reference for botanists, natural resource managers, environmental consultants, students, educators, or anyone simply wanting to learn more about these fascinating habitats. Includes over 800 plant species in 100 plant families, complete coverage of wetland and aquatic species within four major plant groups-Ferns and Fern Allies, Conifers, Dicots, and Monocots. Easy-to-use keys to each plant family, genus, and species. Minnesota map showing county distribution for each species. Endangered, threatened, or special concern wetland plants.
