The habitat selection and movements of 33 radio-collared black bears (Ursus americanus) were monitored from March to December 1988, on Drummond Island, Michigan. An attempt was made to validate a Habitat Suitability Index (HSI) model designed for black bears. Habitat variables required by the HSI model were measured in appropriate vegetation types to determine HSI scores for each adult bear's home range. The movement of bears depended on the distribution and abundance of preferred foods. Significant correlations were not obtained when HSI scores were compared to home-range sizes, cub litter sizes, cub weight gains and mean daily movements. The HSI score for Drummond Island did not correspond well to average age of first reproduction and mean home- range overlap. The black bear HSI model should be revised to better reflect black bear ecology.
Results of the 1961 drumming grouse, grouse brood and woodcock singing censuses at Gratiot-Saginaw State Game Area.
Report on the results of the 1991-1992 River Otter Survey. In order to allow export of river otter (Lutra canadensis) under the Convention on International Trade in Endangered Species (CITES), the Fish and Wildlife Service compiles data on the harvest and status of river otter.
A survey of turkey hunters was conducted following the 2005 fall hunting season to determine turkey harvest and hunter participation.
Report combining and comparing recent deer population data collected from various sources.
Results and discussion of the 1968 rural mail carrier survey of pheasant broods.
The Michigan Department of Natural Resources (DNR) monitors northern bobwhite quail (Colinus virginianus) distribution and relative abundance using whistling surveys and hunter harvest and effort surveys. The whistling survey is the primary index used by the DNR to monitor the status of quail in Michigan. This report summarizes results of the 1999 quail whistling surveys. Additionally, this report discusses results of the 1998 hunter harvest surveys and current regulations. A total of 31 quail whistling surveys were completed in 1999. The overall mean index in 1999 of 5.5 quail heard per route was statistically not different from the index of 5.7 heard in 1998. However, most of the routes showed a decrease in quail heard since 1998. Results indicate that about 5,600 persons spent 26,850 days hunting quail in 1998. This is about 42% fewer hunters than in 1993, the last year in which a quail season was held. Estimates were not available on hunter harvest.
Results of a survey of turkey hunters conducted following the 1987 spring hunting season to determine turkey harvest and hunter participation.
In 1980, the deer pellet group survey was carried out in Region II (the northern half of Michigan's Lower Peninsula). The average over-winter population (uncorrected) was estimated to be 402,915 during the 1979-80 winter. After legal kill and over-winter losses are taken into account, the spring deer population prior to fawning is estimated at 380,572 animals.
In 1995, 35 routes were conducted as compared to 32 routes in 1994. Additional routes were completed but not used in this analysis. Results show that only four counties meet the minimum criteria for having an open season. Since the first quail season in 1961, at least nine counties must meet the minimum criteria to open quail hunting. The quail index decreased eight percent from last year. Ice storms and low temperatures of last winter kept quail numbers at a low level throughout the quail range. The whistling index (average number of calls per stop) was 55 percent lower than 1992.
Report on the results of the December, 1938 bird census at Rose Lake Area.
Report of a survey of a sample furtakers contacted after the 2012 hunting and trapping seasons to estimate the number of participants, days afield (effort), and furbearer harvests.
Summary of the final numbers of the 1952 ruffed grouse survey.
Extensive logging in the 1800's, subsequent fires, and 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 first reintroduced in the 1960's on the U.P.'s Ottawa National Forest. By 1989, they had become sufficiently abundant in all or parts of Baraga, Gogebic, Houghton, Iron, Marquette and Ontonagon counties to allow a limited harvest by trapping. In 1994, additional areas in Alger, Delta, Dickinson, Houghton, Keweenaw, Marquette and Menominee counties were opened to fisher trapping. Trappers were limited to 1 fisher from Unit B as part of their bag limit. Regulations remained the same in 1995. In 1996, the remainder of the Upper Peninsula, with the exception of Drummond Island, was added. The regulations remained unchanged in 1997, 1998, 1999, 2000 and 2001. Since the first trapping season, trappers have been required to submit to the Michigan Department of Natural Resources (DNR) the skulls of fisher for examination and pelts for sealing. In 2001, there was a registered harvest of 381 fisher. Of the 293 fisher submitted for examination, 145 (49.5%) were males and 148 (50.5%) were females. Of the legally trapped fisher submitted for examination, 65.5% (192 of 293) were 1.5 years old or younger. By comparison, last year's fisher harvest consisted of 74.4% (131 of 176) yearlings and juveniles.
The Michigan Department of Natural Resources (DNR) monitors northern bobwhite quail (Colinus virginianus) distribution and relative abundance using whistling surveys and hunter harvest and effort surveys. The whistling survey is the primary index used by the DNR to monitor the status of quail in Michigan. This report summarizes results of the 2000 quail whistling surveys and discusses current regulations. A total of 28 quail whistling surveys were completed in 2000. The overall mean index was 7.9 quail heard per route. In 1999 the overall mean index was 5.5 quail heard per route. However, comparison of 25 similar routes in 1999 and 2000 revealed no significant statistical differences.
Results of the 1964 quail whistling survey conducted in June and July, with distribution map.
This report presents estimates of the spring turkey kill and hunter numbers in Michigan for the 1983 spring turkey season. An estimated 15,435 people hunted 45,703 days during the 1983 spring turkey season. This represents a 4% increase in hunter numbers from the previous season. The estimate of 1,746 (±7%) turkeys harvested in 1983 is very comparable to the 1982 kill of 1,748 birds. The distribution of harvest by turkey management unit is also similar to the previous season. The kill and days hunted per hunter is also comparable to the 1982 season.
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. Only 167 singing male Kirtland's warblers were located in the 1987 census. Ironically, this year's census count of 167 is the same as that of 1974, when the count showed a decline of 23 percent from 1973. The 1975 census showed a 7 percent increase to 179 singing males, rose 12 percent to 200 in 1976, and increased 10 percent to 21.9 in 1977. The next several years will indeed be critical to the fate of this species.
Report on the results of the 2001-2002 Bobcat Survey. In order to allow the export of bobcat (Felis rufus) pelts under the Convention on International Trade in Endangered Species (CITES), the United States Fish and Wildlife Service compiles data on the harvest and status of bobcats. This documentation is necessary to verify the stability of bobcat populations to allow for their continued harvest and the exportation of pelts.
Results of the annual state-wide survey to determine wintering waterfowl populations in Michigan.
Mid-season progress report of data collected during the 1950 ruffed grouse population survey.
A sample of small game license buyers was contacted after the 2003 hunting seasons to estimate the number of people hunting upland game and waterfowl, their days afield, and harvest. Grouse and squirrel hunting seasons were expanded in 2003; thus, additional estimates were calculated for both the expanded and entire seasons. The survey also was used to check whether migratory bird hunters registered with the Harvest Information Program (HIP) and to determine the preferred date for the opening of the 2004 duck hunting season in Michigan.
Report of the results of the 1985 pheasant crowing survey, including 1984 numbers for comparison and interpretation of results.
Results of a deer pellet group survey conducted in the spring of 2001 in most of the Upper Peninsula (UP) and selected units of the northern Lower Peninsula.
The Upper Peninsula (UP) of Michigan supports numerous furbearer species, and the Department of Natural Resources is charged with managing the "Endangered" but rapidly recovering gray wolf (Canis lupus), the reintroduced fisher (Martes pennanti) and marten (M. americana), the Federally regulated bobcat (Lynx rufus) and river otter (Lutra canadensis), and a number of other furbearers of varying status. Harvest information and physical data have been collected as part of the registration process for fisher, bobcat, river otter, badger, and incidental marten captures. Furbearer Winter Track Count Surveys have been attempted in the UP since 1996, and formal summaries of the results of the surveys conducted in 1998-2001 were reported. A winter track count approach was selected, because many of the species of greatest concern are active on the surface of the snow during winter, and suitable snow tracking conditions in the UP normally extend from late January until early April. In 2001, survey routes were redefined as a single stretch of road or trail with minimum right-of-way improvement, approximately 8 km in length. Most of the former route "segments" were designated as "routes", individual routes were surveyed as time and snow conditions permitted, and routes became the sampling unit from which data were analyzed. Ninety-three routes were surveyed in 2002 and routes were surveyed 1-3 days after a marker snow. Data from 9 of 11 furbearers and 4 of 5 other species of interest were collected along the 744.8 km of roads and trails surveyed. Marten tracks were found on 41% of the routes surveyed in 2002. Coyote (Canis latrans) was the most widely distributed furbearer, leaving tracks along 74% of the routes surveyed. Lagomorphs (snowshoe hare, Lepus americanus and cottontail rabbit, Sylvilagus floridanus) were more widely distributed, being detected along 81% of the routes surveyed.
