Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft Oct 2020

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …


The Relationship Between Measures Of Annual Livestock Disturbance In Western Riparian Areas And Stream Conditions Important To Trout, Salmon, And Char, Lindsey M. Goss, Brett B. Roper Apr 2018

The Relationship Between Measures Of Annual Livestock Disturbance In Western Riparian Areas And Stream Conditions Important To Trout, Salmon, And Char, Lindsey M. Goss, Brett B. Roper

Watershed Sciences Faculty Publications

Managing livestock disturbance in riparian zones in a manner that provides economic returns to ranchers while protecting streams is an important aspect of rangeland management on public lands in the western United States. Attempts to balance economic and ecologic outcomes have been made more difficult due to the presence of several salmonid species that are protected under the Endangered Species Act. One approach to proper management of livestock use near streams has been to define the allowable limits of disturbance using 2 metrics, streambank alteration and stubble height. We evaluated 153 stream reaches within the Interior Columbia Basin to determine …


Adoption Of Range Management Innovations By Utah Livestock Producers, Elizabeth Anne Didier May 2002

Adoption Of Range Management Innovations By Utah Livestock Producers, Elizabeth Anne Didier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent years have seen changes in ecological conditions, ownership patterns, and political-legal forces that affect the sustainability of Western range livestock production. Enterprise diversification and implementation of improvements are advocated as ways for ranchers to cope with marginal returns from ranching while better managing resources. However, relatively few ranchers make such substantive changes in their operations, and previous research suggests that rates of adoption may be especially low in Utah.

Using a qualitative approach, this study explored innovation adoption among Utah ranchers. During preliminary interviews with 13 key informants, commitment to traditional ranching lifestyles, the state's settlement pattern, and availability …

Regional Standards For Rangeland Health And Guidelines For Livestock Grazing Management ... A Progress Report Jun 1996

Regional Standards For Rangeland Health And Guidelines For Livestock Grazing Management ... A Progress Report

Range Management

In August 1995, new BLM regulations for rangeland administration went into effect. The new regulations require BLM to establish regional standards for rangeland health and guidelines for grazing management. This publication is a report on the alternatives being considered for the Montana/Dakotas Rangeland Health Standards and Guidelines process.


Livestock As Seed Disseminators For Reseeding Degraded Rangelands: The Role Of Dung In Gap Formation And Plant Establishment, Brian S. Auman May 1996

Livestock As Seed Disseminators For Reseeding Degraded Rangelands: The Role Of Dung In Gap Formation And Plant Establishment, Brian S. Auman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock (cattle and sheep) were examined as seed disseminators for reseeding degraded Intermountain rangelands. "Hycrest" crested wheatgrass [Agropyron desertorum (Fisch. ex Link) Schult. X A. cristatum (L.) Gaert.] seed was fed to yearling Holstein steers and Suffolk ewes. Dung was collected from each animal type and deposited on plots of high and low densities of an annual [cheatgrass (Bromus tectorum L.)] and perennial [squirreltail (Sitanion hystrix Nutt.)] grass species. The experiment evaluated the ability of the dung to suppress the resident vegetation, and the recruitment and establishment of Hycrest seedlings emerging from the dung.

Sheep dung had …


Appendix 1 Public Comments And Forest Service Responses To The Environmental Assessment For 36 Livestock Grazing Allotments On The Shoshone National Forest, United States Forest Service Jan 1996

Appendix 1 Public Comments And Forest Service Responses To The Environmental Assessment For 36 Livestock Grazing Allotments On The Shoshone National Forest, United States Forest Service

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

Forest Service Regulations (36 CFR 215.6d) require publication of this appendix. Material in this appendix addresses comments received from the public during the comment period for the Environmental Assessment for 36 Livestock Grazing Allotments on the Shoshone National Forest. This appendix will be attached to any Decision Notices that may result.


Environmental Assessment For 36 Livestock Grazing Allotments On The Shoshone National Forest, United States Forest Service Jan 1996

Environmental Assessment For 36 Livestock Grazing Allotments On The Shoshone National Forest, United States Forest Service

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

The Shoshone National Forest proposes to issue Term Grazing Permits that will authorize the grazing of livestock on 36 grazing allotments located within the Forest. Permits will be issued for a period of up to 10 years. Part 3 (Special Terms and Conditions) of each permit would contain site specific livestock and rangeland management requirements designed to mitigate existing resource conflicts and implement Forest Plan standards and guidelines specific to each allotment.


Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith May 1976

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.

The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …


Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook Mar 1971

Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook

UAES Bulletins

Desert ranges of the Great Basin area support about 9 million cattle and sheep for 5 to 6 months each winter. Many of these same ranges are used by cattle year-long.

If forage is not available on desert ranges, livestock have to be wintered on farmsteads or in feedlots after they are forced from the mountains and foothills by snow. Since feeding during the winter is expensive and reduces the economic efficiency of the range livestock operation, there is real advantage in properly managing the desert ranges and conserving the supply of forage for winter grazing.

Managing desert ranges for …
