Joe Stell's Life, Career, & Contributions, Susan Kelly

Water Matters!

Representative Joe Stell's retirement after 20 years in the New Mexico Legislature has many people wondering: How will we fare without his knowledge and history ofNew Mexico water matters? Stell viewed one of his most important roles as that of helping new legislators get up to speed on w ater issues. We hope that Water Matters! may assist in this role by providing legislators with background information on some of the issues they will encounter. The Utton Center also wanted to acknowledge Joe Stell's outstanding service to New Mexico, and we have therefore included a brief sketch about his career, …


Local And Regional-Scale Societal Dynamics In Grizzly Bear Conservation, Douglas Andrew Clark Jan 2007

Local And Regional-Scale Societal Dynamics In Grizzly Bear Conservation, Douglas Andrew Clark

Theses and Dissertations (Comprehensive)

Conserving grizzly bear populations is a significant challenge for wildlife managers throughout North America. Much fruitful research has been conducted on the biology of grizzlies, but the human dimensions of bear management remain poorly understood. This imbalance has created conflicts between management agencies and local inhabitants that can jeopardize ecosystem management and planning programs in which grizzlies often feature as key components. Broadly, the goal of this study was to understand how and why such conflicts occur. Qualitative data analysis methods and the policy sciences' interdisciplinary problem analysis framework, along with insights from adaptive governance and co-management concepts, resilience theory, …


An Analysis Of Social Aspects Of Forest Stewardship Council Forest Certification In Three Ontario Case Studies, Melanie Venne Jan 2007

An Analysis Of Social Aspects Of Forest Stewardship Council Forest Certification In Three Ontario Case Studies, Melanie Venne

Theses and Dissertations (Comprehensive)

Forest certification is a market-based tool whereby forest management is evaluated against a set of standards that consider environmental, economic and social elements of sustainability. Certificiation is therefore a means of providing customers with the assurance that forest products are originating from sustainability managed forests. It grew out of the ideal of sustainable forest management (SFM) and pulls from its predecessor the concept of multiple dimensions of sustainability. The focus of this project was the international forest certification scheme Forest Stewardship Council (FSC).

A comparative case study approach was used to examine the social implications of certification in three FSC …

Grassland Songbirds In A Dynamic Management Landscape: Behavioral Responses And Management Strategies, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

In recent decades, earlier and more frequent harvests of agricultural grasslands have been implicated as a major cause of population declines in grassland songbirds. From 2002 to 2005, in the Champlain Valley of Vermont and New York, USA, we studied the reproductive success of Savannah Sparrows (Passerculus sandwichensis) and Bobolinks (Dolichonyx oryzivorus) on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- to mid-July; (2) middle-hayed fields cut once between 21 June and 10 July; (3) late-hayed fields cut after 1 August; and (4) rotationally grazed pastures. Both the number of …

Evaluating Diet Composition Of Pronghorn In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jaret D. Sievers, Jonathan A. Jenks, Chad L. Sexton, Daniel E. Roddy

The Prairie Naturalist

The pronghorn (Antilocapra americana) was reintroduced into Wind Cave National Park (WCNP), South Dakota, in 1914, and thus, has inhabited the Park for nearly a century. During the 1990's, a decline in the population raised concern for the continued existence of pronghorn inside WCNP; an investigation into the observed decline was initiated. Primary objectives of our study were to evaluate diet composition and forage selection by pronghorn in WCNP. Microhistological analysis was conducted on 58 fecal samples collected opportunistically from pronghorn during 2002. Blue grama (Bouteloua gracilis), common juniper (Juniperus communis), and northern bedstraw …


Evaluation Of Habitat Enhancement Structure Use By Spotted Bass, Stanley L. Proboszcz, Christopher S. Guy Dec 2006

Evaluation Of Habitat Enhancement Structure Use By Spotted Bass, Stanley L. Proboszcz, Christopher S. Guy

The Prairie Naturalist

Habitat enhancement is a common and effective method used to positively influence fish populations. However, there is a paucity of speciesspecific evaluations of stream habitat enhancement structures for warmwater fishes. We evaluated use of half-log, rootwad enhancement structure, and simulated undercut bank (LUNKERS) by adult and juvenile spotted bass (Micropterus punctulatus) in natural and experimental streams. Enhancement structures were installed in Otter Creek, Kansas. Adult spotted bass use of natural and enhancement structure was documented weekly during summer and fall of 2001 and 2002 with radiotelemetry. Mean total length (TL) of adult fish was 292 mm (SE = …

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore Dec 2006

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore

The Prairie Naturalist

There have been almost no surveys of herpetofauna at 109 km2 Lostwood National Wildlife Refuge (LNWR) or surrounding counties in northwestern North Dakota, an area possibly undergoing significant environmental change from fossil fuel extraction and use. We used 30 m drift fences to survey amphibian and reptile species in prairie-wetland transition zones at LNWR during mid-May to early-July in 1985 to 1987, and again in 1999 and 2000. We captured only four amphibian and two reptilian species and noted one other reptilian species incidental to our survey. Several species expected to occur in the area were not detected.

Agenda: Celebrating The Centennial Of The Antiquities Act, University Of Colorado Boulder. Natural Resources Law Center, University Of Colorado Boulder. Center Of The American West

Celebrating the Centennial of the Antiquities Act (October 9)

For 100 years, the Antiquities Act has been used by nearly every President in the 20th century to set aside and protect lands threatened with privatization and development. The list of lands first protected under the Antiquities Act – and that might never have been protected without it – is truly remarkable. Many of our most treasured national parks including the Grand Canyon, Olympic, Zion, Arches, Glacier Bay, and Acadia, began as national monuments. All told, Presidents have issued 123 proclamations setting aside millions of acres of land under the Antiquities Act.
