Native Vascular Plant Inventory of Eagle Heights Woods, 
Wally Bauman Woods and  Tent Colony

Joshua Sulman July 25, 1998

This plant inventory includes the species seen during the period from late April to late July, 1998, on walks at weekly intervals through the western three sections of the Preserve.  Also included are some species seen other years and some not yet blooming at the end of July, but observed in a vegetative state.

The three areas observed were Eagle Heights Woods, Wally Bauman Woods, and the western part of Tent Colony Woods.  Each section has a unique topography and microclimate resulting in different sets of plant communities and species for each area. 

Eagle Heights has a steep north-facing hillside and a shallower slope to the south, and is entirely wooded.  The north-facing side is so steep in some areas that there are exposed rock ledges, with characteristic cliff plants on them.  The cooler microclimate allows for plant species not found on the south face of the hill.  The woods is a characteristic Southern Dry-Mesic Forest, with a tall canopy dominated by red oak.  The top of Eagle Heights is drier with a canopy of mainly white oak, and a groundlayer characteristic of a Southern Dry Forest. The other sides of the hill grade between these two forest types, with some species found on some sides and not others.  In the spring, plants of the same species bloom about a week earlier on the south slope than on the north slope of Eagle Heights.

Wally Bauman Woods continues in the Dry-Mesic Forest of the north side of Eagle Heights down toward the lake.  The slope is not quite as steep as in Eagle Heights, but is still a good climb.  Lake Mendota is about 150 feet lower than the top of Eagle Heights.  There are some cliff-like areas of erosion along the shore with associated cliff species. 

To the east into Tent Colony Woods, the forest grades into a Mesic Forest of mostly sugar maple.  In the interior, the groundlayer is sparse except for a few spring ephemerals.  Along the shore, there are hints that the area was once more open, with some open-grown oaks and savanna wildflowers.  Near the parking lot, around the small beach and cliff are a number of interesting plant species not found in the rest of the three sections observed.  The situations are associated with Shaded Cliff and Exposed Cliff communities.  Along Lake Mendota Drive on the south side of Tent Colony Woods, there are plants that arrived there and had an advantage growing in the disturbance of the road embankment that are not found elsewhere in the areas observed.

In the table below, numbers following native species and lower-case letters following non-native species correspond to the map for local species. 
Letters follow names of plants with a wide distribution in the specified areas.
