I. Teaching
Values for Birds
A. Presence
of horned owls. Class can find pellets, and see
how they register food habits. Class can find and
examine remnants of prey brought in by adults to feed young. (Grazing
or altering the two woodlots [on Eagle Heights and Second
Point] would evict these owls.)
B. Spring
waterfowl show on University Bay. About twenty
species of ducks, divers and shorebirds visible at close
range. The duck show is more varied than that of Arboretum. (Dredging,
filling, or altering the bay would probably spoil this.)
C. Pheasants.
The pheasant population is much more easily observed than that
of the Arboretum because of the adjacent open fields. Most
mortality from mowers can be demonstrated on the University
alfalfa fields: this is not possible on the Arboretum.
D. Small
marshes. The three small units of marsh (on the
north side of Picnic Point, in University Bay near the picnic
Point entrance and next to Willows Beach) make possible the
study of segregated marsh populations, which is not possible
on the large Arboretum marshes.
II. Teaching
Values for Mammals
A. Foxes.
This area contains the closest remaining foxes. Tracks,
droppings, and dens can be shown to class.
B. Rabbit
pressure. For some unknown reason this area has
a consistently higher rabbit population pressure than any
other area near Madison, hence browsings are exaggerated,
and hence more easily seen by class.
C. Muskrats
and minks. Closest available population.
III. Existing
Conditions Which Need to be Preserved for Wildlife Teaching
A. University
Bay and adjoining remnants of marsh.
B. University
Creek and small marsh at its mouth.
C. Picnic
Point marshy pond.
D. Two
woodlots.
IV. Existing
Conditions Which Need to be Abated for Wildlife Teaching
A. Pollution
of Willow Creek.
B. Plantation
of exotic trees and shrubs.
C. Rats
on University Bay Dump (the depleted sandpit).
D. Shooting
and trapping on University Bay.
V. Wildlife
Teaching Exhibits Which Need to be Added to the Area
A. Rabbit
browsing inside and outside an exclosure.
B. Shade
tolerance of plantings inside and outside of a woods.
C. Plant
succession plowings (one unit each year) to show wildlife food
and cover plants in relation to successional stages.
D. Perch-posts
in marsh to show effect on redwing blackbird territories.
