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