In 1951, Harold Mayfield organized the first census of the species - a project generally recognized as the first such undertaking for any songbird. Since that time, thirteen more censuses have been carried out; the first three at ten-year intervals and since 1971, annually. The highlight of the 1982 census was the discovery of the first Kirtland's warbler ever found in the Upper Peninsula. Dr. John Probst, ecologist with the U.S. Forest Service. found one singing male near Gwinn. Overall, workers tallied 207 singing males, all in Michigan. This represents a drop of 25 (10.8 percent) from the 1981 count of 232, and 14.8 percent less than the 243 males found in 1980. The 1980 count was the highest in the entire series from 1971 to 1982, but still well below the 432 present in 1951 and the 502 in 1961.

Extensive logging in the' 800's and subsequent fires plus heavy trapping through the 1920's led to the extirpation of the fisher (Martes pennanti) from its former range in the Upper Peninsula (U.P.). Fisher were reintroduced in the 1960's on the U.P.'s Ottawa National Forest. By 1989, they had become sufficiently abundant in Baraga, Gogebic, Houghton, Iron, Marquette and Ontonagon counties to allow a limited harvest by trapping. In the four seasons prior to 1993, trappers were allowed to harvest 1 fisher annually. In 1993, the bag limit was increased to 3 per trapper. The season bag limit regulations remained the same in 1994, but additional areas were opened to fisher trapping. These areas included Keweenaw, Menominee and parts of Houghton, Dickinson, Marquette, Alger, and Delta counties. Trappers were limited to 1 fisher in the newly opened area as part of their bag limit. The registered harvest for 1994 was 417 fisher. In addition, 4 fisher were killed by vehicles and 5 were accidentally trapped. Equal numbers of males (163) and females (163) were examined. Of the legally trapped fisher submitted for examination, 72% (235 of 326) were 1.5 years old or younger.

For the third consecutive year, a statewide black bear (Ursus americanus) harvest zone and quota system was utilized in 1992. The same eight bear management units, seven in the Upper Peninsula, including Drummond Island. and one covering much of the northern Lower Peninsula, were opened to hunting. There were two hunt periods for each of the Upper Peninsula units except Drummond Island, which had only one. There was only one hunt period in the Lower Peninsula. In 1992, a total of 4,442 hunters harvested 1,225 bear during the 1992 season, a twelve percent increase in the harvest from the previous year. Twenty-seven percent of the hunters with a harvest tag were successful in 1992 compared to 22 percent in 1991. The composition of the harvest, 56 percent males and 44 percent females, indicated a decrease in the proportion of males compared to the previous year. Hunter satisfaction is used as an indicator of the success of the bear management program. Hunters were asked to rate their 1992 bear hunting experiences. Forty·five percent of the hunters rated their bear hunting as "good" or "very good." Thirty-one percent reported a rating of "poor" or "very poor."

During the spring of 1996, the deer pellet group survey was conducted in the Upper Peninsula. The average overwinter population (unadjusted) in the Upper Peninsula was estimated to be 702.796. After legal kill and overwinter losses were considered. the spring deer population prior to fawning was estimated at 583,181 animals in the Upper Peninsula.

The first Kirtland's warbler (Dendroica kirtlandii) census was organized by Harold Mayfield in 1951. The census was to be repeated every 10 years and the second census in 1961 recorded a total similar to that of 1951. The census of 1971 however revealed a precipitous drop in the population--a decline of approximately 60 percent from the 1961 count. In order to monitor the population more closely, censuses have been conducted every year since 1971. 210 singing male Kirtland's warblers were located in the 1986 census. Several census personnel commented on a possible increase in the number of males which sang only infrequently. This, plus several days with less than ideal weather conditions, could mean that the census count may be slightly low, and the population is essentially holding its own.

Results of the annual mail carrier survey of pheasant broods, 1961.

Michigan's sixteenth turkey season saw an all time record harvest of 844 birds. It exceeded the 1979 season by 217 birds. an increase of 35 percent. The 1980 winter was relatively mild in comparison to the last four years and there was an unusually good mast crop available in all turkey areas. The turkeys were not hampered to any extent by deep snows and prolonged sub-zero temperatures. In general it was an open winter and they were free to roam. Harvest of turkeys for the three major turkey districts were Mia - 644 birds; Baldwin - 147 birds; and Allegan - 53 birds. Mio's increase was 156 birds or 32 percent more than last year; Baldwin's was 34 more birds, a 30 percent increase; and Allegan had 27 more, which was a 103 percent increase.

Results of the research and survey carried out on fishers that were killed by motor vehicles or accidentally trapped during winter and spring 1984, 1985, and 1986.

In 1986, the deer pellet group survey was carried out in Region I (Upper Peninsula) and Region II (Northern Lower Peninsula). The average overwinter population (unadjusted) in Regions I and II were estimated to be 267,907 and 462,840 respectively, during the 1985-86 winter. After legal kill and over-winter losses are considered, the spring deer population prior to fawning was estimated at 214,540 animals in Region I and 422,012 in Region II.
