Effects Of Flooding On Herbaceous Species Of The White Cedar-Tamarack Woods In Cedarburg Bog, James A. Reinartz, Steven Kroeger

Field Station Bulletins

A part of the northern lowland forest of Cedarburg Bog was flooded about eight years ago as a result of clogged road culverts. Studies of the effects of flooding on species composition, productivity, hydrology and soils were begun in 1982. Post flooding studies will commence when the natural water levels are restored (ca 1984). This paper compares the frequencies of herbaceous species in the flooded woods with an adjacent portion of unflooded woods. The pattern of species' abundances within the flooded woods is related to the degree of inundation and grazing history of the site. Significantly different frequencies were found …

Vascular Plants Near The Margins Of Their Range In Cedarburg Bog. Part Ii. Dicots, James A. Reinartz, Gay E. Reinartz

Field Station Bulletins

There are two species of gymnosperms and 18 monocots that are near the southern edge of their geographic range in Cedarburg Bog (Reinartz and Reinartz 1981). Six of these may actually reach their range boundary in the bog. Nine species of the Cyperaceae and seven Orchidaceae comprise the bulk of the monocot species that are near their southern limits. The purpose of this paper is to provide an annotated listing of dicot species which have geographically marginal populations in Cedarburg Bog.

Summer Birds Reaching The Margins Of Their Range At The Cedarburg Bog And The Uwm Field Station, John H. Idzikowski

Field Station Bulletins

In a previous article, Reinartz and Reinartz (1981) described the monocot and gymnosperm plants that reach their range limits at the Cedarburg Bog. The bog forest consists primarily of·white cedar (Thuja canadensis) and tamarack (Larix laricina) and includes a string bog plant community, all typical of wetlands further north. The summer fauna also possesses an ecologically northern relict flavor. This is especially true of the most conspicuous vertebrates, the birds. Many bird species found in the bog are more closely associated with the transitional and boreal forests of Canada and northern Wisconsin than with the deciduous forests and fields that …

Stand Risk Rating For The Southern Pine Beetle: Integrating Pest Management With Forest Management, Gordon L. Autry

Faculty Publications

Stand risk rating for the southern pine beetle.

Dendroctonus frontalis Zimm., is a first step toward dealing with a serious but sporadic insect problem. Two approaches, one utilizing readily available resource data, the other employing data obtained from aerial photographs, illustrate application of current knowledge to meet the protection needs of resource management-the primary role of integrated pest management. During a 36-month period in Louisiana, high-risk stands accounted for 13.4 infestations per 1,000 acres, four times the rate of low-risk stands; in Texas high-risk stands accounted for 9 .9 infestations per 1 ,000 acres during 1973-1978, almost five times the …

Recreation Opportunity Spectrum With Implications For Wildlife-Oriented Recreation, Perry J. Brown

Forest Management Faculty Publications

Resource planning has undergone transitions over the years from a site to area to regional orientation and from a single function to integrated resource management orientation. Wildlife and recretation resource planning have been part of this evolution, which has been stimulated somewhat by recent land management planning-oriented legislation such as the National Forest Management Act and the Federal Land Policy and Management Act.

During the last couple of years, a system for recreation planning within the context of integrated resource planning has emerged. It is called Recreation Opportunity Spectrum (ROS) planning and arose as an old idea was made operational …

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf

Avian Cognition Papers

An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.

Mississippi Timber Removals - A Ten Year Presentation, G. H. Weaver, Steven H. Bullard

Faculty Publications

Mississippi is a major producer of manufactured forest products, and most of the timber required by Mississippi's forest industry is produced and harvested within the State. A severance tax on timber harvested in Mississippi is paid to the Mississippi State Tax Commission, and annual reports of timber removals are prepared by the Commission.

Behavioral And Genetic Diversity During Dispersal: Analysis Of A Polymorphic Esterase Locus In Southern Pine Beetle, Dendroctonus Frontalis, L. Zack Florence, Paul C. Johnson, Jack E. Coster

Faculty Publications

Dispersal behavior of the southern pine beetle, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae), in response to synthetic aggregating pheromone (frontalin) indicates an exponential decrease in response with distance from the site of emergence. Differential response during dispersal among genotypes at a polymorphic esterase locus was found by using starch gel electrophoresis. These differences produced allelic distributions that predict increased genetic diversity concurrent with increasing dispersal distance from the source population.

Training Biologists In Institutional Topics: Federal Needs And Viable Approaches, Stephen A. Miller, Dennis L. Schweitzer

USDA Forest Service / UNL Faculty Publications

Consider the following question:
"A proposed development activity that promises substantial economic benefits will have significant adverse impacts on fish and wildlife resources in the area. What percentage of all your agency wildlife and fisheries professionals could develop and present a fully professional defense for the faunal interests in the area to an audience largely oriented towards commodity development?"
Before you become too uneasy with your answer to that question, let me pose another:
"Your wildlife and fish budget request to carry out a proposed program, regulatory activity, project or operation has been challenged. What percentage of all your agency …

Spotted Owl Research And Management In The Pacific Northwest, Eric D. Forsman, Kirk M. Horn, William A. Neitro

USDA Forest Service / UNL Faculty Publications

In recent years, a rapidly expanding body of research has made wildlife biologists and land managers increasingly aware that old-growth forests are critical wildlife habitat. This has come at a time when old-growth forests are rapidly being eliminated in order to meet human demands for wood products. In Oregon, for example, it is anticipated that virtually all remaining old-growth forests on commercial forest lands will be harvested by the year 2020 (Beuter et al. 1976). Thereafter, regenerating forests on cutover areas will be intensively managed and harvested every 60-80 years on most sites. If history is a good example, it …

Livestock And Riparian-Fishery Interactions: What Are The Facts?, William S. Platts

USDA Forest Service / UNL Faculty Publications

The riparian environment has become a key consideration in the planning and management of the public lands. This highly productive habitat receives many uses, some of which conflict with one another. Because there are conflicts that need immediate attention, range and fishery managers are making complicated, hurried decisions, often without the benefit of adequate knowledge or experience. In addition, interpretations emerging from riparian studies are often confusing and contradictory, inhibiting the manager's decision-making abilities.
Leopold (1974) stated that fish and wildlife habitat in western rangeland has experienced and is experiencing a steady deterioration under livestock grazing. The same year, Heady …

Resource Management Thrusts And Opportunities: Fish And Wildlife-A Fuller Dimension To Improved Resource Management, John B. Crowell, Jr.

USDA Forest Service / UNL Faculty Publications

It has been a little more than a year since President Reagan was inaugurated, and a little less time than that since I was confirmed and sworn in as assistant secretary of agriculture. We have moved to establish and implement some changed emphases in our resource management programs. So, by now there should be little mistake about our intent to improve natural resource management on the national forests. We intend to increase the productivity of these resources without corresponding increases in federal appropriations. We intend to generate increased receipts to the U.S. Treasury by emphasizing revenue-producing activities such as timber …

Solving The Habitat Dispersion Problem In Forest Planning, Stephen P. Mealey, James F. Lipscomb, K. Norman Johnson

USDA Forest Service / UNL Faculty Publications

The National Forest Management Act (NFMA) of 1976 (16 U .S.c. 1600) requires that each National Forest, by 1985, prepare one integrated management plan that provides for multiple use and sustained yield for goods and services (36 CFR 219). Such plans must, by inference, emphasize single resources only to the extent that thresholds or minimum legal conditions for all other resources are always provided (Clawson 1975). The goal for wildlife to be met by each forest plan is: manage wildlife habitats to maintain viable populations of all existing native vertebrate species in the planning area (the forest) and maintain and …

Habitat Classification-Assessments For Wildlife And Fish, Hal Salwasser, William B. Krohn

USDA Forest Service / UNL Faculty Publications

Comprehensive planning and management of natural resources require the assessment of existing and future conditions offish and wildlife. Fish and wildlife, hereafter referred to as wildlife resources, can be inventoried and assessed either in terms of animals or habitats. Both approaches are useful given certain management objectives. For example, population inventories in concert with other data, are often used to assess the impacts of hunting. In contrast, habitat inventories are used to evaluate the impacts of grazing, or other land and water uses, on wildlife resources. Our objective is not to compare or contrast the two approaches, but to focus …

Project Applications Of The Forest Service Rocky Mountain Region Wildlife And Fish Habitat Relationships System, Judy L. Sheppard, Dale L. Wills, James L. Simonson

USDA Forest Service / UNL Faculty Publications

Wildlife and Fish Habitat Relationships (WFHR) is a Forest Service system for integrating wildlife and fish information and assessment data into interdisciplinary land and resource management. WFHR is a comprehensive organization of information in a format useful for managing wildlife through the management of their habitats. The WFHR System assists the Forest Service in meeting its goal of managing wildlife and fish habitats, both for species diversity as well as for individual species of management concern.
The Rocky Mountain WFHR System (USDA Forest Service 1981a) organizes information on 853 vertebrate animal species occurring on National Forest System lands in the …

Relationships Between Avifauna And Streamside Vegetation, Evelyn L. Bull, Jon M. Skovlin

USDA Forest Service / UNL Faculty Publications

Riparian microhabitats in coniferous forests in northeastern Oregon are sensitive to alteration. They have been used disproportionately by people, livestock, and wildlife. These uses have altered the habitats, specifically by reducing vegetative structure (Thomas 1979).
Land management agencies are revegetating depleted riparian zones to improve fish and wildlife habitat. Managers need information on the response of birds to kinds and structures of vegetation so that wildlife objectives can be met.
Several studies have dealt with the relationships of riparian vegetation and avifauna (Carothers and Johnson 1975, Ferguson et al. 1976, Stauffer 1978). Although these studies determined some of the habitat …

Needs For And Approaches To Wildlife Habitat Assessment, Jack Ward Thomas

USDA Forest Service / UNL Faculty Publications

For many years prior to 1969, wildlife was essentially defined, in the practice of governmental bodies, as those species hunted for sport, trapped for furs, controlled to accomplish human objectives, or of particular aesthetic value. Governmental management of these species was based on funding obtained from or supported largely by clearly identified constituencies.
Universities evolved specialized programs in wildlife biology and management to produce the knowledge and trained professionals to meet these needs. Many such programs were oriented to training in zoology which emphasized the animal and populations while paying less attention to habitat.
As a result, most wildlife research …
