The Nebraska Natural Heritage Program has been collecting information and data including published literature, field observations and vegetation plot data over the last 10 years of development of Nebraska’s natural community classification. The classification contains 27 wetland and 36 upland communities including forest, woodland, shrubland, herbaceous, and sparsely vegetated (e.g. rock outcrop) types. The community types were distinguished primarily on plant species composition and to a lesser extent on soils, hydrology and geographic location. The classification contains descriptions of each community type that include dominant species, soils, range, and other ecological information. The classification is designed to be flexible enough …

Identification Of A Fish Host Of The Inflated Heelsplitter Potamilus Inflatus( Bivalvia: Unionidae) With A Description Of Its Glochidium, Kevin J. Roe, Andrew M. Simons, Paul Hartfield
Kevin J. Roe
A survey of the fishes of the lack Warrior River was undertaken to determine fish host(s) of the federally threatened inflated heelsplitter, Potamilus inflatus. Seven hundred-twenty individual fishes representing 30 species were examined; mussel glochidia were found on 10 individual fishes representing nine species. Potamilus inflatus glochidia were only found infesting one freshwater drum (Aplodinotus grunniens), which is concordant with previous findings for the genus Potamilus. The morphology of P. inflatus glochidia is described and compared to P. purpuratus.

1997 Rapid Ecological Assessment Northern Great Plains Steppe Ecoregion: Western And Central South Dakota, Northwestern Nebraska, Eastern Wyoming, A Final Report, Terri Hildebrand
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
In an effort to gain a more complete understanding of existing vegetative communities of the Northern Great Plains Steppe Ecoregion, rapid ecological assessment was undertaken throughout the ecoregion during the field season of 1997. Field office personnel of The Nature Conservancy and private contractors evaluated previously delineated regions in accordance with methodology determined in May of 1997. The following document presents results of the rapid ecological assessments performed by Hildebrand Contracting. The purpose of this document is to provide The Nature Conservancy with information to help determine the vegetative features of regions sampled. The specific areas and boundaries for evaluation …
