Agenda: The Future Of Natural Resources Law And Policy, University Of Colorado Boulder. Natural Resources Law Center, Rocky Mountain Mineral Law Foundation

The Future of Natural Resources Law and Policy (Summer Conference, June 6-8)

The Natural Resources Law Center's 25th Anniversary Conference and Natural Resources Law Teachers 14th Biennial Institute provided an opportunity for some of the best natural resources lawyers to discuss future trends in the field. The conference focused on the larger, cross-cutting issues affecting natural resources policy. Initial discussions concerned the declining role of scientific resource management due to the increased inclusion of economic-cost benefit analysis and public participation in the decision-making process. The effectiveness of this approach was questioned particularly in the case of non-market goods such as the polar bear. Other participants promoted the importance of public participation and …

Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr. Jun 2007

Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.

The Prairie Naturalist

We quantified the use of black-tailed prairie dog (Cynomys ludovicianus) colonies as habitat for the burrowing owl (Athene cunicularia) in southwestern Kansas and southeastern Colorado. We used incidental sightings and breeding season avifauna surveys to document the presence of the burrowing owl on black-tailed prairie dog colonies, non-colonized rangeland, and cropland during the spring and early summer. Burrowing owl rarely was observed on noncolonized rangeland and cropland sites, and black-tailed prairie dog colonies appear to be used substantially as a habitat type for the burrowing owl in the region encompassing Cimarron and Commanche National Grasslands in …

Satellite Image Processing For Biodiversity Conservation And Environmental Modeling In Kyrgyz Republic National Park, Galina N. Fet

Theses, Dissertations and Capstones

There is a need for extensive surveys of living organisms at a global scale; digital data exchange and storage is an essential part of such studies. Biodiversity inventory of fungi, which play an essential role in the health of the mountainous conifer forests of a developing country – Kyrgyz Republic, was linked to the vegetation classification produced from the high-resolution satellite imagery. Terra ASTER and SRTM90 imagery was used as a base map for the ecosystem modeling of the species and habitat distribution and for the three-dimensional representation, especially valuable for the mountainous landscapes of the Ala Archa National Park. …

Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren Jan 2007

Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren

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

The data presented here suggest that 18,411 (± 224) khulan inhabit southern Mongolia with a density of 1.4 individuals per 1,000 km2 within the 157,525 km2 territory of its actual distribution. The Dornogobi province contains the highest number of khulan with a mere 67%, while 20% are found in the Ömnögobi province, 12% are in Djungarian Gobi and only 1% in the Gobi-Altay and Bayankhongor provinces. According to the proportion of foals and yearlings within each aimag, the Dornogobi, Ömnögobi east and Khovd populations have an average reproduction rate.

Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov

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

The kulan (Equus hemionus kulan) is the only odd-toed ungulate left in the wild in northern Eurasia. In the 1930s, the kulan survived in southern Turkmenistan only. In the 1940s, kulans were found only in an area named Badkhyz in Turkmenistan. To conserve the last natural population of this subspecies of kulan the Badkhyz Natural Reserve was established in 1941. The historical and contemporary distribution, fluctuation in numbers, conservation and sci research of kulan populations in the Badkhyz Natural reserve are reviewed in this paper.

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

The history of the discovery and the exploration of the hemione populations (Equus hemionus PALLAS) from Central Asia (Mongolia, northwest China, northeast Tibet, Kazakhstan, and Russian Siberia) from the 13th century to approximately 1950 are compiled with the aim to provide materials for a taxonomic and population genetic revision of the dziggetais. Data on their phenotypic differentiation, historical distribution status, and their husbandry history in European zoological gardens, are reviewed, as is the gradual emergence of concepts of how to identify and to classify these populations. Hemiones were an important historical case in the discussion of how to represent …


Providing The Best Of Both Worlds: Balancing Conservation And Recreation In A System Of Protected Areas In Texas, Kellen Allison Smith Jan 2007

Providing The Best Of Both Worlds: Balancing Conservation And Recreation In A System Of Protected Areas In Texas, Kellen Allison Smith

LSU Master's Theses

Societies are becoming increasingly urban and isolated from natural areas. Protecting certain natural areas is vital for building and maintaining resilience in ecological systems for the continued conservation of biodiversity and provision of ecological services. The International Union for the Conservation of Nature and Natural Resources (IUCN) promotes the development of systems of protected areas within nations and regions as a sustainable means of preserving the biodiversity within natural areas. Allowing sustainable ecotourism and wildlife-based recreation activities in protected areas can provide economic incentives to surrounding communities making protection an attractive alternative to more extractive forms of land use. Managing …


Probabilistic Estimation Of Water Conservation Effectiveness, David E. Rosenberg Jan 2007

Probabilistic Estimation Of Water Conservation Effectiveness, David E. Rosenberg

Civil and Environmental Engineering Faculty Publications

An analytical method is derived to describe the distribution of water quantity saved among customers within a water-use sector who adopt a water conservation action. Analytical results tend toward lognormal distributions with long tails, quantifying a smaller subset of customers that show potential to achieve large savings. Example effectiveness distributions are shown for seven long-term conservation actions potentially implemented by urban, domestic water users in Amman, Jordan. Monte Carlo simulations verify the analytical derivations. The probabilistic outputs contrast with common methods that estimate conservation action effectiveness as a product of typical (average) characteristics for disaggregated customer groups. Implications to size …


Responses Of Pond-Breeding Amphibians To Wildfire: Short-Term Patterns In Occupancy And Colonization, Blake R. Hossack, Paul Stephen Corn Dec 2006

Responses Of Pond-Breeding Amphibians To Wildfire: Short-Term Patterns In Occupancy And Colonization, Blake R. Hossack, Paul Stephen Corn

United States Geological Survey: Staff Publications

Wildland fires are expected to become more frequent and severe in many ecosystems, potentially posing a threat to many sensitive species. We evaluated the effects of a large, stand-replacement wildfire on three species of pond-breeding amphibians by estimating changes in occupancy of breeding sites during the three years before and after the fire burned 42 of 83 previously surveyed wetlands. Annual occupancy and colonization for each species was estimated using recently developed models that incorporate detection probabilities to provide unbiased parameter estimates. We did not find negative effects of the fire on the occupancy or colonization rates of the long-toed …


Human And Non-Human Primate Co-Existence In The Neotropics: A Preliminary View Of Some Agricultural Practices As A Complement For Primate Conservation, Alejandro Estrada Nov 2006

Human And Non-Human Primate Co-Existence In The Neotropics: A Preliminary View Of Some Agricultural Practices As A Complement For Primate Conservation, Alejandro Estrada

Ecological and Environmental Anthropology (University of Georgia)

In this paper I address the general perception that agricultural activities are the principal threat to primate biodiversity in the tropics and argue that in Neotropical landscapes some agricultural practices may favor primate population persistence, and that this situation merits attention and investigation. To explore these issues, I examined three interrelated pressures upon tropical forests for the Mesoamerican and Amazon basin regions: human population growth trends, levels of poverty and human development and deforestation rates. I also present relevant results of recent surveys completed on the presence and activities of primate populations in agroecosystems in several landscapes in Mesoamerica. I …


Ethnoprimatology: Toward Reconciliation Of Biological And Cultural Anthropology, Erin P. Riley Nov 2006

Ethnoprimatology: Toward Reconciliation Of Biological And Cultural Anthropology, Erin P. Riley

Ecological and Environmental Anthropology (University of Georgia)

One of the hallmarks of the discipline of anthropology is its holistic approach to the study of what it means to be human. A perennial challenge to the discipline, however, is the question of whether biological and cultural anthropology can truly coexist given their traditionally disparate epistemologies and methodologies. In this paper, I argue that the emerging field of ethnoprimatology, which focuses on the ecological and cultural interconnections between human and nonhuman primates, has real potential to bridge these two subfields. I support my argument by discussing the theoretical rationale of an ethnoprimatological approach with regard to the notion of …


Human Dimensions Of Northern Muriqui Conservation Efforts, Karen B. Strier, Jean P. Boubli, Francisco B. Pontual, Sergio L. Mendes Nov 2006

Human Dimensions Of Northern Muriqui Conservation Efforts, Karen B. Strier, Jean P. Boubli, Francisco B. Pontual, Sergio L. Mendes

Ecological and Environmental Anthropology (University of Georgia)

The northern muriqui (Brachyteles hypoxanthus) is endemic to Brazil’s Atlantic Forest, and it ranks among the most critically endangered primates in the world. Roughly 25% of the species is found in the 957 ha forest at the Estação Biológica de Caratinga/RPPN-Feliciano Miguel Abdala, in Minas Gerais, Brazil. The long-term research and conservation efforts at this site have received considerable attention, and public awareness and educational campaigns about northern muriquis have been highly effective. Nonetheless, very little about the human dimensions of these efforts have been explicitly described. In this paper, we focus on three distinct, but interconnected dimensions: …


Policy Tools For Smart Growth In New England, New England Environmental Finance Center Nov 2006

Policy Tools For Smart Growth In New England, New England Environmental Finance Center

Smart Growth

Across New England communities have been experiencing a rapid outward surge of development away from our community and downtown centers. Effects of sprawl include a loss of wildlife habitat, farm and timber lands; increased costs of community services and higher taxes; auto-dependency, longer commutes, and increased congestion; increases in air and water pollution; a sedentary lifestyle and increased obesity; and losses to one’s sense of place and social ties.

State-level responses to sprawl have surfaced throughout New England in recent years. This report describes 11 examples of these responses, representing all six New England states and a diversity of recent …

Realizing The Potential Of Family Forests: Tools To Facilitate Habitat Conservation, Drue Deberry, Julie H. Moore

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The management of family-owned forests is discussed in light of conservation issues and development pressures. Safe Harbor Agreements and Candidate Conservation Agreements with Assurances are voluntary tools that can be used to protect conservation values, particularly habitat for threatened or endangered species. A case history of forest management practices to sustain the gopher tortoise in the Southeast is given.


Sage-Grouse Restoration Project: Evaluating The Effects Of The Farm Bill Conservation Practices On Sage-Grouse, Terry A. Messmer Oct 2006

Sage-Grouse Restoration Project: Evaluating The Effects Of The Farm Bill Conservation Practices On Sage-Grouse, Terry A. Messmer

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The Office of Management and Budget is demanding increased accountability of funds used to implement conservation practices and strategies. Although current Farm Bill policy provides priority funding for projects that are designed to enhance species conservation, it does not allocate funds to conduct the evaluations needed to document the effect of conservation practices on wildlife. The Sage-Grouse Restoration Project (SGRP) is a cooperative agreement with the Natural Resource Conservation Service (NRCS), designed specifically to facilitate evaluations to determine the effect of conservation practices and technologies implemented under the 2002 Farm Bill on restoring or enhancing sage-grouse habitat on private lands. …


Tropic And East Fork Irrigation Company, Tropic Ditch Replacement Project, Environmental Assessment, Bureau Of Reclamation, Provo Area Office Oct 2006

Tropic And East Fork Irrigation Company, Tropic Ditch Replacement Project, Environmental Assessment, Bureau Of Reclamation, Provo Area Office

All U.S. Government Documents (Utah Regional Depository)

The purpose of this project is to reduce the amount of salt entering the Paria River and ultimately the Colorado River. One way to reduce the amount of salt reaching the Colorado River is to eliminate seepage from the historic Tropic Ditch. The Bureau of Reclamation, Provo Area Office has proposed funding for the project under the Colorado River Salinity Control Program. In addition to reducing the amount of salt loading, the project would also conserve water lost to evaporation and seepage.

The purpose of this Environmental Assessment (EA) is to analyze the potential environmental consequences of the proposed construction …

2005 Nutrient And Sediment Monitoring Report Ballard Creek Near Arkansas/Oklahoma Line, Marc Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle, Marty Matlock

Arkansas Water Resources Center Technical Reports

The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas' Water Quality Assessment report, the Soil Conservation Service River Basin Study, and several University of Arkansas studies. Thirty-seven sub-watersheds have been identified by the SCS in the Arkansas portion of the Illinois River basin. In the Arkansas portion of the Basin, the Illinois River, Evansville Creek, Baron Fork, Cincinnati Creek, Muddy Fork, Moores Creek, Clear Creek, Osage Creek and Flint Creek were all classified as not supporting their designated use as primary contact recreation …
