A Revised Measurement Methodology For Conifer Needles Spectral Optical Properties: Evaluating The Influence Of Gaps Between Elements, Mark A. Mesarch, Elizabeth Walter-Shea, Gregory P. Asner, Elizabeth M. Middleton, Stephen Chan

School of Natural Resources: Faculty Publications

Gaps are unavoidable when compositing small or narrow plant parts (e.g., conifer needles, twigs, narrow leaves, and leaflets) on sample holders in preparation for measuring spectral optical properties. The Daughtry et al. (1989) (A new technique to measure the spectral properties of conifer needles. Remote Sens. Environ. 27:81-91.) method of measuring conifer needle optical properties utilizes a relatively large gap fraction (approximately 0.3-0.6) and needles painted black on one surface of the sample from which the gap fraction of the sample is indirectly determined. Following this protocol typically results in distortions in optical properties, including underestimates in transmittance (sometimes negative …

The Relative Importance Of Patch Area And Perimeter–Area Ratio To Grassland Breeding Birds, Christopher J. Helzer, Dennis E. Jelinski

School of Natural Resources: Faculty Publications

Habitat fragmentation has been implicated as a major cause of population decline in grassland birds. We tested the hypothesis that a combination of area and shape determines the use of grassland patches by breeding birds. We compared both species richness and individual species presence in 45 wet meadow grasslands in the floodplain of the central Platte River, Nebraska. Bird data were collected through the use of belt transects and supplemented by walking and listening outside transects. Our data supported our primary hypothesis that perimeter–area ratio, which reflects both the area and shape of a patch, is the strongest predictor of …

Iron-Mediated Remediation Of Rdx-Contaminated Water And Soil Under Controlled Eh/Ph, J. Singh, Steven Comfort, Patrick Shea

School of Natural Resources: Faculty Publications

Soil and water contaminated with hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a serious environmental problem at several active and abandoned munitions production facilities. Zero-valent iron (Fe⁰) can effectively remediate RDX-contaminated soil and water. The objective of this study was to manipulate Eh and pH for enhanced Fe⁰-mediated destruction of RDX. This was accomplished by monitoring RDX destruction under controlled Eh-pH conditions (Eh: −300 to +150 mV; pH: 2−10). Decreasing Eh and pH increased RDX destruction in aqueous solution. Treating 20 mg of RDX L-1 (90 μM) under a static Eh of −150 mV and pH 7 with 20 g …

Brownfield Redevelopment Strategies For Gary, In,, Kirstin Toth, Donald T. Iannone

All Maxine Goodman Levin School of Urban Affairs Publications

The Great Lakes Environmental Finance Center conducted a technical assistance workshop for Gary, Indiana officials on June 29, 1999. This workshop represented an important step in the city’s efforts to address its brownfields cleanup and redevelopment needs. The city has begun its participation in a regionally-awarded brownfields pilot grant from the U.S. Environmental Protection Agency (EPA). The workshop agenda focused discussion on overcoming the barriers to brownfields redevelopment and the financing basics of brownfields redevelopment. These topics were discussed in the context of the redevelopment of the Airport Development Zone and a major area of Gary’s waterfront.

Available Resources Of The Fire Clay Coal In Part Of The Eastern Kentucky Coal Field, Stephen F. Greb, Gerald A. Weisenfluh, Robert E. Andrews, John K. Hiett, James C. Cobb, Richard E. Sergeant

Report of Investigations--KGS

Available resources for the Fire Clay coal were calculated for a 15-quadrangle area in the Eastern Kentucky Coal Field. Original coal resources were estimated to be 1.8 billion tons (BT). Coal mined or lost in mining was estimated at 449 million tons (MT), leaving 1.3 BT of remaining Fire Clay resources in the study area. Of the remaining resources, 400 MT is restricted from mining, primarily because the coal is less than 28 in. thick, normally considered too thin to mine underground using present technology. The total coal available for mining in the study area is 911 MT, or 52 …

Oyster Reef Habitat Restoration : A Synopsis And Synthesis Of Approaches; Proceedings From The Symposium, Williamsburg, Virginia, April 1995, Mark Luckenbach, Roger L. Mann, James A. Wesson

Reports

This volume has its origin in a symposium held in Williamsburg, VA in April 1995, though most of the chapters have been significantly revised in the interim. The primary purpose of the symposium was to bring together state fisheries managers involved in fisheries-directed oyster enhancement and research scientists to refine approaches for enhancing oyster populations and to better develop the rationale for restoring reef habitats. We could hardly have anticipated the degree to which this been successful. In the interim between the symposium and the publication of this volume the notion that oyster reefs are valuable habitats, both for oysters …

What Does Smart Growth Mean For Housing?, Karen A. Danielsen, Robert E. Lang, William Fulton

Public Policy and Leadership Faculty Publications

Barely noticed amid the returns from the 1998 midterm elections was a quiet revolution that goes to the heart of how and where Americans live. While most news accounts focused on the high-profile candidate elections, voters across the nation-in Democratic and Republican areas alike-approved more than 160 state and local ballot measures intended to preserve open space and limit urban sprawl.

The coalition forming around the idea of limiting sprawl includes environmentalists, farmers, big-city mayors, and some developers. But perhaps most important, the so-called "smart growth" movement also includes many suburban voters who are fed up with growth. For example, …

Redevelopment Strategies For The Usx/Cement Plant Site In Duluth, Minnesota,, Kirstin Toth, Donald T. Iannone

All Maxine Goodman Levin School of Urban Affairs Publications

In May 1999, the Great Lakes Environmental Finance Center (GLEFC) conducted a strategy-building workshop in Duluth, Minnesota. The purpose of the workshop was to assist the City of Duluth in its efforts to develop actions leading to the successful redevelopment of the USX/Cement Plant site. Particular emphasis was placed on financing strategies pertinent to properties with a history of environmental contamination, often characterized as brownfields. Due to its long history as an industrial site, the 65-acre Cement Plant had its share of perceived environmental contamination, as well as real contaminants detected during previous site assessments and a current Phase I …

1999 Wildlife Management Area Threatened And Endangered Species Inventory, Final Report, Robert F. Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This study was undertaken to determine the extent of threatened and endangered (T&E) species habitats and high-quality native plant communities on Nebraska Game and Parks Commission (NGPC) Wildlife Management Areas (WMAs). The Nebraska Natural Heritage Program (NHP) is responsible for environmental reviews of state projects that may impact threatened and endangered (T&E) species in Nebraska, including proposed management actions on state Wildlife Management Areas (WMA). These environmental reviews require a significant amount of NHP staff time, and frequently find no adverse impacts associated with the proposed management actions. This survey was undertaken to improve Nebraska Game and Parks Commissions (NGPC) …

Inventory Of The Central Mixed-Grass Prairie Ecoregion Of Kansas And Nebraska, Hillary Loring, Mike Bullerman, Kelly Kindscher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

An inventory of potential high quality mixed-grass prairie ranches and large properties within the Central Mixed-Grass Prairie Ecoregion of Kansas and Nebraska was conducted in the spring and summer of 1999. Emphasis during the inventory was placed on identification of relatively intact landscapes. Significant ranches within those untilled landscapes were visited. An interview of the owners or managers of those properties was coupled with a survey of the vegetation. Assessments of quality were based on species composition, continuity of ground cover, observations of livestock impact, and viability of the community types present.

The objectives of this study were to:

1) …
