Evaluating taxonomic surrogates for floristic quality assessment of wetlands
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-05-01

An examination of temporal trends, regional variation, and habitat-type differences in site-level Floristic Quality, and their implications for the use of Floristic Quality Assessment
Floristic Quality Assessment (FQA) is a measure of site conservation value. It is premised on using an area’s plant species composition and diversity to estimate its human disturbance and degradation levels. FQA metrics are increasingly popular and influential for making land conservation, …

Floristic quality assessment of grassy slough preserve in Johnson County, Illinois
In the Lower Mississippi River Alluvial Valley (LMRAV), which stretches from southern Illinois to the Gulf of Mexico, approximately 7 million hectares of bottomland hardwood forest have been converted to agricultural production. Approximately 750,000 hectares of the eastern United States have been …

Plant introductions and community dynamics across environmental gradients in Great Lakes coastal wetlands
… vital ecosystem services, including water quality improvement, flood mitigation, and fish and wildlife habitat. However, many of these wetlands have been lost, and those that remain face various threats, including invasion by nonnative plants. Within coastal wetlands, the uppermost edge of …

Assessment of the ecological integrity of two wetland sites within Eastern Michigan University’s Fish Lake Environmental Education Center (FLEEC)
… Plant species richness was used to conduct Floristic Quality Assessments (FQA) using the coefficient of conservatism and wetland indicator status for each species. The Michigan Rapid Assessment Method (MiRAM) was conducted as a more comprehensive assessment of each ecosystem. The bog had an …

Democratizing plant biodiversity data with coefficients of conservatism for the vascular flora of Tennessee and Kentucky
Floristic Quality Assessments (FQAs) measure an ecosystem's quality and can be applied to any ecosystem. FQAs consist of two parts: a species checklist and each species’ coefficient of conservatism (c-value). C-values are integers that describe a species’ tolerance to anthropogenically disturbed …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… wetlands; and mean coefficient of conservatism, floristic quality, and percent canopy closure, which were higher at natural wetlands. Using cluster analysis and nonmetric multidimensional scaling (NMDS) with post-hoc PERMANOVA comparisons, I determined that understory vegetative communities were …

Vegetation structure and inferred patterns of functional group attrition in a shrub encroached old field and tallgrass prairie mosaic
… transects and eight located randomly in high-quality reference prairie habitat. Two community types were identified through field observation and reinforced by cluster analysis, indicator species analysis, and Nonmetric Multidimensional Scaling (NMS). The communities differed significantly in …

Invertebrate Egg and Plant Seed Banks in Natural, Restored, and Drained Wetlands in the Prairie Pothole Region (USA) and Potential Effects of Sedimentation On Recolonization of Hydrophytes and Aquatic Invertebrates
… and invertebrate egg bank composition of high quality reference wetlands (i.e., having no history of cultivation) to previously farmed nondrained, restored, and drained seasonal and semipermanent wetlands in the Missouri and Prairie Coteau, and Glaciated Plain physiographic regions of the PPR. …

Validating A Kentucky Wetland Rapid Assessment Method For Forested Riverine Wetlands Using Vegetation, Bird Surveys, And Landscape Analysis
… variables were (1) percent forested, (2) floristic quality assessment index score and percent adventive, and (3) percent adventive and Carex species richness for Metric 2 (Buffers and Surrounding Land Use); Metric 4 (Habitat Reference Comparison); and, Metric 6 (Vegetation, Interspersion, …

Prairie Restoration and Species Diversity: A Comparison of Propagation Success Between Seeded and Planted Forbs
… importance. In order to achieve the highest quality prairie that consists of the most diverse communities, researchers and prairie managers need to continue to revise best management practices. Currently prairie managers introduce grasses and forbs by seeding disturbed areas and then manage …

A Vegetation-Based Index of Biotic Integrity for Wetlands of Kentucky
… to wetlands. Professional judgments of wetland quality are inherent in regulatory decisions related to preservation and mitigation, but many states, and until recently including Kentucky, have no standard, quantifiable means of assessing wetlands to guide the decision process. A rapid assessment …

A quantitative study of the vegetation of dry and dry-mesic sand prairies in Central and Northwestern Illinois
… Although the greatest amount of remaining high quality prairie in Illinois is in the form of dry and dry-mesic sand prairie, little research has been conducted on these sandy grasslands. This thesis focuses on studying the floristic and structural diversity, as well as the possible causes of …

Restoration implications of land management on aboveground vegetation and seed bank composition of grassland communities in Illinois
A variety of non-prairie landscapes are restored to prairie on a yearly basis including pastures, croplands, and old fields. Most of these restoration efforts do not take into account the seed bank associated with these non-prairie lands as a potential source of plant diversity or weedy …

Vegetation-Based Metrics Of Biotic Integrity For Assessing The Ecological Condition Of Wetlands Of Kentucky
… have been developed to quantify the ecological quality of the waters of the United States. Kentucky recently adopted a rapid method for assessing the ecological condition of wetlands, but there is no standardized means to rigorously assess the ecological quality of its wetlands. Indices of …
