A Vegetation-Based Index Of Biotic Integrity For Wetlands Of Kentucky, Noelle Newman Smith Jan 2016

A Vegetation-Based Index Of Biotic Integrity For Wetlands Of Kentucky, Noelle Newman Smith

Online Theses and Dissertations

Wetland ecosystems have experienced severe declines across the United States, prompting efforts to assess the status of remaining wetlands and regulate their development. The Clean Water Act and the policy of “No Net Loss” have resulted in a system of permitting and mitigation for impacts 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 method has recently been developed for Kentucky, but there is no intensive assessment method …


Monitoring Standing Herbage Of Mid-Grass Prairie On The Fort Pierre National Grassland, South Dakota, Daniel W. Uresk Jun 2012

Monitoring Standing Herbage Of Mid-Grass Prairie On The Fort Pierre National Grassland, South Dakota, Daniel W. Uresk

The Prairie Naturalist

Monitoring vegetation with a modified Robel pole on the Fort Pierre National Grassland was evaluated for combined shallow clay and loamy overflow ecological sites (dominated by warm-season grasses), and for clayey ecological sites (dominated by cool-season grasses). My objectives were to 1) develop a relationship between visual obstruction readings (VOR) and standing herbage, 2) provide guidelines for vegetation monitoring, and 3) evaluate vegetation monitoring during the growing season for clayey ecological sites. The relationship between visual obstruction readings and standing herbage was linear and regression coefficients were highly significant (P < 0.001) for both ecological types. Cluster analyses for shallow clay and loamy overflow ecological sites grouped the VOR and standing herbage (kg•ha-1) into 4 resource categories. Monitoring with 4 transects will provide adequate information to estimate standing herbage within 259 ha (1 section). Three resource categories (VOR + herbage) for clayey ecological sites were defined by cluster analyses. Monitoring with 4 transects was determined to provide reliable estimates of standing herbage. July validation of vegetation with the developed clayey ecological site model will provide reliable monitoring of standing herbage from July through November for this ecological site.


Vegetation Trends On A Waste Rock Repository Cap In The Northern Black Hills, Andrew C. Korth, Gary E. Larson, Lan Xu, Thomas E. Schumacher May 2010

Vegetation Trends On A Waste Rock Repository Cap In The Northern Black Hills, Andrew C. Korth, Gary E. Larson, Lan Xu, Thomas E. Schumacher

The Prairie Naturalist

We assessed successional trends, long-term vegetation sustainability, and soil surface protection during the 2005-2007 growing seasons on the 32-ha Ruby Gulch Waste Rock Repository cap. The cap consisted of 150 cm of rock and soil covering a polyethylene membrane which in turn covered mining waste rock in order to prevent leaching of heavy metals and acidic water into streams. Following construction in 2003, a contractor applied a grass-forb seed mixture to provide soil-surface protection especially for steeply sloped portions of the cap. In 2005, we established 56, 1-m2 plots, and 20, 20-m transects to annually measure canopy cover, basal …


Environmental Adaptations Of The Gobi Desert Plants In Mongolia: An Example Of C4-Plants, Ts. Tsendeekhuu, Clanton Candler Black Jan 2005

Environmental Adaptations Of The Gobi Desert Plants In Mongolia: An Example Of C4-Plants, Ts. Tsendeekhuu, Clanton Candler Black

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper presents the results of our studies on the ecological adaptations and geographical distribution of plants with C4-photosynthesis in Mongolia using 13C isotope discrimination.

Previous studies identified about 80 C4-species in 8 families in the Mongolian flora. Our investigations lead to the identification of four additional species, which can be regarded as C4-plants. Orostachys spinosa (-16.26‰ 13C), O. thyrsiflora (-16.86‰ 13C), O. fimbriata (-16.15‰ 13C), and Euphorbia humifusa (-23.29‰ 13C). However, as the discrimination level for Euphorbia humifusa is very similar to that of C3-plants it may be switching between C3 and C4 types …
