Vascular Plants Near The Margins Of Their Range In Cedarburg Bog. Part Ii. Dicots, James A. Reinartz, Gay E. Reinartz Apr 1982

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 Apr 1982

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 …
