SMALL MAMMALS OF THE TOFT POINT SCIENTIFIC AREA, DOOR COUNTY-WISCONSIN: A
PRELIMINARY SURVEY 
Wendel J. Johnson, University of Wisconsin 
Center—Marinette 
ABSTRACT 
 J~ ive and snap trapping techniques were used to examine the presence and
abundance of small mammals at Toft Point. The eleven species found include
northern taxa such as (Lepus, Clethrionomys) which are typical of boreal
forests, and southern forms (Microtus, Sciurus carolinensis and Glaucomys
sabrinus). The southern species, with their main distribution south of Door
Peninsula, are probably the most recent additions to the Toft Point small
mammal assemblage, indicative of a northward advance after retreat of Wisconsin
glaciation. 
INTRODUCTION 
 This project surveyed the terrestrial small mammal community of the Toft
Point Scientific Area to determine what mammals were present and whether
they were exclusively boreal species. Results are compared to previous studies
of Door County mammals (Jackson, 1961; Long, 1974) and to a small mammal
study done in similar habitats in northern Michigan (Manville, 1949). 
 Toft Point lies approximately 2.4 km northeast of Bailey's Harbor, Wisconsin.
The history of the Toft Point Natural Area, as related to me primarily by
Emma Toft of Bailey's Harbor, is one of a relatively unexploited forest.
Miss Toft's parents settled there in the second half of the 19th Century
and her father, Kersten Toft, was employed by a Michigan firm interested
in the limestone underlying the land. Limestone was mined and ships would
