Upper Mississippi River; Navigation Pool 8; vascular flora; Southwestern Wisconsin vascular plants; La Crosse Co., Wisconsin; Vernon Co., Wisconsin; Upper Mississippi Wildlife Refuge; dredge material flora
As a result of comprehensive field work performed during 1975 and 1976 followed by herbarium activities, a complete picture of the composition of the vascular flora of Navigation Pool 8 of the Upper Mississippi River has been obtained. The area includes a 47.5 km (23.3 mile) section of the Mississippi River between Dresbach, Minnesota and Genoa, Wisconsin. A total of 482 species in 88 families were collected. The Gramineae was the largest family with 33 genera and 63 species, while Carex (Cyperaceae) was the largest genus with 26 species. The flora comprises communities here defined as alluvial forest, willow forest, shrub, sedge meadow, Phalaris meadow, emergent, floating-leaved, submergent, spit and shore, levee, old field, and dredge spoil.
