Use of clearcut islands on 12 impoundments by nesting giant Canada geese (Branta canadensis maxima) were investigated during January-May 1980, at the Gratiot-Saginaw State Game Area, Michigan as a basis for management recommendations to maintain and increase goose production. Sixteen islands (ranging in size from 1.8 x 2.3 - 3.7 x 34.7 m) that correspond with the nest site spacings of the local goose flock and that were similar in dimensions to known successful nesting islands were selected for treatment. All woody vegetation greater than 17 cm high was cut and removed from the islands. A total of 11 nests of giant Canada geese was found on 11 islands. Treated islands accounted for 36 percent (4) of the nesting islands. Nesting geese were observed using treated islands on two impoundments that previously were devoid of suitable nesting sites, one pair increased the nesting population on an impoundment. The other seven islands used by nesting geese were completely devoid of woody vegetation. This study implies that the Gratiot-Saginaw giant Canada geese will nest on clearcut islands and exhibit an apparent preference for treated sites over untreated islands with woody overstory vegetation. Management recommendations include removal of woody overstory vegetation greater than 17 cm high that correspond with preferred nest site spacings of the local goose flock.

Creating wetlands for wildlife is a relatively new science, and wetlands constructed from design recommendations provided by consultants and resource management agencies have had limited wildlife-use evaluation. The purpose of this study was to monitor wildlife use and physical characteristics of semi-permanent wetlands constructed in 1992 and 1994. A total of 2,345 waterbird observations was recorded during 40 counts, which averaged 59 waterbirds/day on the 22-pond complex or 7 waterbirds/wetland ha/day. Waterfowl accounted for 83% of total waterbird use. Mallard, blue-winged teal, and gadwall ducks were the most commonly observed species, comprising 64% of the waterfowl use. Canada geese accounted for 11% of the waterfowl use. The most common diving ducks were bufflehead, common goldeneye, and hooded merganser, however, their combined use accounted for only 10% of the waterfowl activity recorded. The most common shorebirds were yellowlegs and killdeer, totaling 80% of the shorebird use. Sandhill cranes and American bitterns comprised 87% of the wading bird use. Three-year old wetlands accounted for 79% of the constructed aquatic zone available to waterbirds but 91% of the duck use. One-year old wetlands received comparatively high use by Canada geese and shorebirds (44% and 59% of total use for these groups, respectively). Use by wading birds was also relatively high on the 4 newest wetlands (45% of total wading bird group), however, sandhill cranes accounted for much of this use. When sandhill cranes were omitted from the wading bird data set, use of new wetlands fell to 2% for the group.

A compromise agreement was reached in November, 1980 among environmentalists, oil companies, and the State of Michigan for carefully controlled hydrocarbon development in the Pigeon River Country State Forest (PRCSF). A part of this agreement stipulated that the oil companies would fund a two-phase research program. The objective of Phase I was to identify critical resource features - wildlife, forest, recreational, and aesthetic - associated with hydrocarbon development of Unit I (31,340 acres of the total 82,785 acres in the forest) and, more specifically, to incorporate these findings in the site selection process for oil and gas development. As part of the Phase I studies, a survey was carried out to determine the recreational use on all of Unit I for an entire year. This report covers the findings of that survey.
