Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Journal of the Iowa Academy of Science: JIAS
Forested seep wetlands dominated by skunk cabbage (Symplocarpus foetidus) occur frequently in the Canoe Creek watershed of the Upper Iowa River, but this type of wetland has not been described systematically in the upper Midwest. The goal of this study is to document the herbaceous plant flora of five seeps. Although individual seeps are small (200-500 m2), they provide habitat for a high number of plant species. Five seeps with total area less than 0.2 ha supported more than 120 native vascular herbaceous taxa, 20 of which have a coefficient of conservatism (C-value) of 7 or …
The Vascular Flora Of Clay Prairie State Preserve (Butler County, Iowa): Recommendations To The Iowa State Preserve System, Edwin L. Freese, William R. Norris
The Vascular Flora Of Clay Prairie State Preserve (Butler County, Iowa): Recommendations To The Iowa State Preserve System, Edwin L. Freese, William R. Norris
Journal of the Iowa Academy of Science: JIAS
Clay Prairie State Preserve (1.2 ha) is an upland prairie located in Butler County, IA, and represents one of the last remnants of black-soil tallgrass prairie in northeast Iowa. An annotated checklist of the vascular flora of Clay Prairie is presented here, based on a previously published flora of the preserve and recent field work conducted by the authors between 1997 to 2001, and 2008 to 2011. The preserve contains a diverse vascular flora representing 50 families, 145 genera and 214 taxa (174 native to Iowa). In comparison with 26 larger prairies (4 to 121 ha) protected in the Iowa …
The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson
The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson
Journal of the Iowa Academy of Science: JIAS
A vascular plant survey of Boone County, Iowa was conducted from 2005 to 2008 during which 1016 taxa (of which 761, or 75%, are native to central Iowa) were encountered (vouchered and/or observed). A search of literature and the vouchers of Iowa State University's Ada Hayden Herbarium (ISC) revealed 82 additional taxa (of which 57, or 70%, are native to Iowa), unvouchered or unobserved during the current study, as having occurred in the county. This total of 1098 taxa (979 species, 57 varieties, 39 subspecies, 23 hybrids) places Boone County first in vascular plant richness among 18 published county inventories …
A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
Journal of the Iowa Academy of Science: JIAS
A survey of Iowa's floristic literature and herbarium resources indicates that while there is not uniform coverage of plant groups and regions, a great deal is known about the Iowa flora. Taxonomic and floristic studies are ongoing, despite evidence of a decreased number of researchers with expertise and interest in Iowa's flora and changing emphases in academic research. Current knowledge is sufficient for the production of an Iowa Flora, and an Iowa Flora committee to initiate this project is proposed.
Floristic Composition And Conservation Status Of Fens In Iowa, John A. Pearson, Mark J. Leoschke
Floristic Composition And Conservation Status Of Fens In Iowa, John A. Pearson, Mark J. Leoschke
Journal of the Iowa Academy of Science: JIAS
Over 200 extant fens of varying condition were documented during an extensive inventory conducted in Iowa between 1986 and 1991. Approximately half of the extant fens support endangered, threatened, special concern, or other rare plant species. Approximately 25 fens are outstanding conservation prospects with intact vegetation, high species richness, and rare species. Nearly 40% of all potential fen sites have been destroyed by cultivation or damage; another 30% remain unknown due to lack of a field visit, but most appear on aerial photographs to be very small, disturbed fragments. In addition to their traditionally recognized range in northwest Iowa, fens …
