Post-Settlement Land Uses And Their Effects On The Cedarburg Bog, Nevin J. Farley, Peter J. Salamun Oct 1973

Post-Settlement Land Uses And Their Effects On The Cedarburg Bog, Nevin J. Farley, Peter J. Salamun

Field Station Bulletins

During a study of the plant species of a lowland hardwood stand at the western edge of the Cedarburg Bog (Farley, 1973), it was noted that significant environmental changes had occurred here and throughout the bog which resulted in the present-day vegatation patterns. Many of these changes can be attributed to the various post-settlement land-use practices which were employed in the Town of Saukville (TllN, R21E), Ozaukee County, Wisconsin, where this bog is located. To document this information a literature survey was made of the various studies which ha ve been carried out in this area (Cutler, 1936; Grittinger, 1969; …


Prairie Establishment At The Field Station, Philip B. Whitford Oct 1973

Prairie Establishment At The Field Station, Philip B. Whitford

Field Station Bulletins

Early in the development of the Cedar-Sauk Field Station it was decided to attempt establishing a sample of prairie vegetation as an experimental and demonstration project. Although none of the field station land had prairie soil and the nearest site of original native prairie was probably at least twenty miles distant, we felt that this area was close enough to the original prairies climatically so that most of the prairie species native to southeastern Wisconsin should be able to survive. If even moderately successful, it would provide an additional habitat for studies of animal life at the station, a demonstration …


Breeding Birds Of The Forested Portions Of Cedarburg Bog, Charles M. Weise Oct 1973

Breeding Birds Of The Forested Portions Of Cedarburg Bog, Charles M. Weise

Field Station Bulletins

In 1971 the Wisconsin Scientific Areas Preservation Council inaugurated a program of annual breeding bird surveys in the various state scientific areas, carried out by members of the Wisconsin Society for Ornithology and coordinated by Mrs. Evelyn Warner. The object is to provide documented quantitative data for assessment of bird population trends, specifically as an index to possible environmental deterioration. The upland deciduous (maple-beech) woods at the UWM Field Station and a large part of the adjacent Cedarburg Bog are included in the scientific areas system, destined for preservation with minimal management for scientific research and education. As part of …

Rate Of Growth Of Tamarack (Larix Tarcina) In Cedarburg Bog, Cynthia Meyer Apr 1973

Rate Of Growth Of Tamarack (Larix Tarcina) In Cedarburg Bog, Cynthia Meyer

Field Station Bulletins

This study was undertaken to determine the influence of bog conditions on growth rate of tamarack (Larix larcina). The Cedarburg Bog in Ozaukee County, Wisconsin presents a unique opportunity for such study since it includes the southernmost string bog in the United States (Grittinger, 1970). My results demonstrate very slow growth of tamarack in Cedarburg Bog both in diameter and height. Differences in growth rates depend on the particular area of the bog, aeration, and mineral availability. As indicated by other studies, much more work is needed to determine how various factors affect growth of trees as well as other …


Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male Apr 1973

Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male

Field Station Bulletins

Most studies of the family life of young birds after they leave the nest have been descriptive and anecdotal with little quantitative behavioral data, despite the many interesting problems involved in interactions of the members of a family. The objectives of this study were to determine: 1) the behavior of parents and young Black-capped Chickadees (Parus atricapillus) at the time of leaving the nest, 2) how the parents and young behave towards each other during the period when the young are dependent on their parents, 3) the factors responsible for the final disruption of the family. Since aggression was anticipated …


Submergent Macrophytes In Theresa Marsh, James Mcnelly, Jeffrey Klopatek Apr 1973

Submergent Macrophytes In Theresa Marsh, James Mcnelly, Jeffrey Klopatek

Field Station Bulletins

Marshes form the interface between upland and aquatic systems and, like most transitional zones, provide habitat diversity which may support a great variety of life. Marshes may act as valves or sinks to regulate the flow of mineral nutrients from terrestrial systems (especially from agricultural or urban systems) to aquatic zones. Freshwater marshes and wetlands are ranked with coastal estuaries as highly productive areas and play an important role in converting the sun's energy to organic matter.

Recreation Research—So What?, Perry J. Brown, Allen Dyer, Ross S. Whaley Jan 1973

Recreation Research—So What?, Perry J. Brown, Allen Dyer, Ross S. Whaley

Forest Management Faculty Publications

The authors contend that most recreation research cannot stand the question, "So what?” From that point the article proceeds to a prescription for a meaningful approach to recreation research, which links recreation research to planning within a systems context. Researchable questions are posed dealing with preferences and behavior, resource capabilities and environmental impacts, and the nature and dynamics of institutions for the original state, process, and desired state segments of a planning system.

Aspen Bibliography

A study was made to investigate the potential of several local puckerbrush or weed trees and shrubs as sources of fiber for papermaking. It is an extension of previous studies which were reported in Technical Bulletin 49 of the Life Sciences and Agriculture Experiment Station, University of Maine at Orono.

Wood Production And Kraft Pulping Of Short-Rotation Hardwoods In The Pacific Northwest, Fred L. Schmidt, Dean S. Debell Jan 1973

Wood Production And Kraft Pulping Of Short-Rotation Hardwoods In The Pacific Northwest, Fred L. Schmidt, Dean S. Debell

Aspen Bibliography

For decades foresters and fiber-using industries throughout the world have been concerned with the problem of future procurement of wood fiber. Research has progressed on several promising approaches to this problem, including fertilization, genetic improvement, better control of competition, and more complete utilization. Recently another alternative has been suggested --- the production of hardwood fiber on very short rotations with coppice regrowth. The concept was first proposed by McAlpine et al. (1966) under the name, "silage sycamore". Since that time, tests of "silage" forestry have been initiated with other hardwood species in many regions of the United State and Canada …
