National List Of Plant Species That Occur In Wetlands: Intermountain (Region 8), Porter B. Reed, Jr., National Ecology Research Center May 1988

National List Of Plant Species That Occur In Wetlands: Intermountain (Region 8), Porter B. Reed, Jr., National Ecology Research Center

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

The National List of Plant Species That Occur in Wetlands represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The U.S. Fish and Wildlife Service initially developed the list in order to provide an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (FWS/OBS 79/31) to assist in the field identification of wetlands. Plant species that occur in wetlands, as used in the National List are defined as species that have demonstrated an ability to achieve maturity and reproduce in an environment where all or …


Arcata Sports Complex Project, Susie Van Kirk May 1988

Arcata Sports Complex Project, Susie Van Kirk

Susie Van Kirk Papers

The City of Arcata is developing a sports complex, including playing fields and structures, on its property lying south and west of 7th and Union Streets. Prior to the commencement of construction, an archaeological investigation was performed to determine the extent and significance of a previously-identified prehistoric site. In addition to artifacts associated with the prehistoric time period, historic artifacts were also encountered. To assist in the evaluation of these artifacts, research of the historic component of the property was undertaken. This report discusses the historic environment and land use, land ownerships, biographical information on some of the families associated …


A Model Of Energy Expenditure In White-Tailed Jackrabbits (Lepus Townsendii) Based On Integrated Studies Of Energetics And Field Ecology, Gordon L. Rogowitz May 1988

A Model Of Energy Expenditure In White-Tailed Jackrabbits (Lepus Townsendii) Based On Integrated Studies Of Energetics And Field Ecology, Gordon L. Rogowitz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field and laboratory studies were conducted to develop a model of energy expenditure in a population of white-tailed jackrabbits (Lepus townsendii). Field work in southwestern Wyoming during 1985-87 showed that the breeding season commenced at snowmelt and ceased during late- July drought. Adult females reproduced relatively synchronously and produced a mean of three litters annually. Greatest fetal production occurred in the second litter period. Collections indicated a 1:1 sex ratio, few jackrabbits >2 years-old, and a density of 7 animals / km2 in the population. Postnatal growth was sigmoidal, culminating in heavier adult females than males. Using …

Jack Shaw Bridge, Susie Van Kirk Apr 1988

Jack Shaw Bridge, Susie Van Kirk

Susie Van Kirk Papers

To adequately assess the historical significance of the Mad River suspension bridge near Mountain View, commonly referred to as the Jack Shaw Bridge, it was necessary to research not only the bridge but the surrounding area as well. Resulting information provides a context or association for understanding the bridge's role in local history.

Instream Flow Protection in the Western United States: A Practical Symposium (March 31-April 1)

Conference speakers included University of Colorado School of Law professors Lawrence J. MacDonnell and Charles F. Wilkinson.

Virtually all western states now provide some kind of legal recognition for instream flows. On March 31-April 1, the Natural Resources Law Center will present a symposium on the different approaches taken in these states, with emphasis on such major issues as the purposes for instream flows, the quantities of water needed for these purposes, enforcement of instream flow rights, federal instream flow claims, private instream flow claims, and transferring consumptive water rights to instream flow rights. Speakers include representatives from state agencies …

Effects Of Implementing Epa's Endangered Species Protection Program On National Forest System Lands, Shelley Witt, Glen Contreras, Max M. Ollieu Mar 1988

Effects Of Implementing Epa's Endangered Species Protection Program On National Forest System Lands, Shelley Witt, Glen Contreras, Max M. Ollieu

Vertebrate Pest Conference Proceedings: 13th (1988)

In 1986, the U.S. Environmental Protection Agency (EPA) initiated an effort to comply more fully with the Endangered Species Act. This effort became their "Endangered Species Protection Program." The possibility of such a program was forecast in 1982 when Donald A. Spencer gave a presentation to the Tenth Vertebrate Pest Conference on "Vertebrate Pest Management and Changing Times." This paper focuses on current plans for implementing the EPA's Endangered Species Protection Program as it relates to the USDA Forest Service. It analyzes the potential effects this program will have on the agency, using the pocket gopher (Thomomys spp.), strychnine, and …


Problems Associated With Beaver In Stream Or Floodway Management, Wendy S. Fitzgerald, Ronald A. Thompson Mar 1988

Problems Associated With Beaver In Stream Or Floodway Management, Wendy S. Fitzgerald, Ronald A. Thompson

Vertebrate Pest Conference Proceedings: 13th (1988)

In California, beaver (Castor canadensis) were first recognized for their value as a furbearer. Additionally, in many areas, beaver are considered desirable if not essential components of stream and wetland ecosystems. Where beaver and human activity overlap, beaver have become nuisance animals causing direct damage through dam building, flooding, bank denning, and loss of agricultural crops. Other problems such as the threat of levee failure and subsequent flooding, increases in undesirable brush growth due to a raised water table, restricted access due to flooding, and an increased mosquito population resulted in the Department of Water Resources (DWR) developing a beaver …


Badgers (Taxidea Taxus) As Occasional Pests In Agriculture, Steven C. Minta, Rex E. Marsh Mar 1988

Badgers (Taxidea Taxus) As Occasional Pests In Agriculture, Steven C. Minta, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 13th (1988)

The badger (Taxidea taxus). because of its strong propensity for digging, is considered North America's fossorial carnivore, feeding mostly on ground squirrels, pocket gophers, and mice throughout much of the western and midwestern continent. Badger excavations, primarily in search of food, produce mounds and deep holes which can damage alfalfa and other crops and damage farm equipment and water systems. Depredations include poultry, waterfowl, and eggs. Overall, the badger is considered a relatively minor vertebrate pest. As a furbearer it is considered a renewable natural resource. Most local pest problems are currently reduced through leghold trapping and shooting. Habitat modification …


A Decade Of Use Of Livestock Guarding Dogs, Raymond Coppinger, Lorna Coppinger, Gail Langeloh, Lori Gettler, Jay Lorenz Mar 1988

A Decade Of Use Of Livestock Guarding Dogs, Raymond Coppinger, Lorna Coppinger, Gail Langeloh, Lori Gettler, Jay Lorenz

Vertebrate Pest Conference Proceedings: 13th (1988)

Results from a ten-year study of livestock guarding dogs show that the dogs are an effective tool for reducing predation. Average reduction attained by five strains of dogs (Anatolian Shepherds, Maremmas, Shar Planinetz, Anatolian/ Shars, Maremma/Shars) was 64%, with predation reduced to zero for 53% of reporting producers in 1986. Variations in trustworthy, attentive and protective behavior of the dogs were breed-specific, and offer mechanisms for improving the system.
