A random sample of bear hunters was contacted after the 2007 hunting season to determine hunter participation, hunting methods, bear harvest, and hunter satisfaction. In 2007, an estimated 8,900 hunters spent nearly 64,000 days afield and harvested about 2,181 bears; a decrease of nearly 17% from 2006. Statewide, 25% of hunters harvested a bear. Baiting was the most common hunting method used to harvest bears, although hunters using dogs had greater hunting success than hunters using bait only. Statewide, about 50% of hunters rated their hunting experience as very good or good. Most hunters (68%) approved of the preference-point system for the distribution of hunting licenses.

Rose Lake Wildlife Research Area is located on the border of Shiawassee and Clinton counties, 12 mi northeast of Lansing. Mammals have been an object of study on the research area since its founding in 1938. Through the years, records have been collected on mammals frequenting the area. The amount of data gathered, as well as the methods used for collection, were not consistent from year to year. Therefore, the records are not complete enough to document population sizes or fluctuations. They do, however, provide knowledge of the mammal species present on the area and give an indication of their relative abundance. The purpose of this report is to document the presence and relative abundance of all species of mammals known or thought to be present on the Rose Lake Area from 1938 through 1980.

The Michigan Department of Natural Resources uses population estimates to assess population status and determine harvest permit quotas for black bear management. The tetracycline survey uses a 2 occasion mark-recapture design to derive a population estimate for the bear population of the Upper Peninsula. We evaluated the survey to identify bias in the estimate and violation of assumptions in the surveys procedure. We also evaluated the survey for efficiency in procedures and methodology and appropriate scale of application. We examined the surveys data both statistically and geographically, and compared surveys data to harvest data. We also simulated surveys conditions to identify the potential magnitude of biases. We make recommendations to minimize the effects of violating surveys assumptions and to improve surveys efficiency.

A survey of bear hunters was conducted after the 2019 hunting season to determine hunter participation, hunting methods, bear harvest, and hunter satisfaction.

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.

A random sample of bear hunters was contacted after the 2003 hunting season to determine hunter participation, hunting methods, bear harvest, and hunter satisfaction. In 2003, an estimated 8,600 hunters spent about 63,000 days afield and harvested nearly 2,500 bears, an increase in harvest of 8% from 2002. Statewide, 29% of hunters harvested a bear. Baiting was the most common hunting method used to locate and harvest bears. Statewide, most hunters (54%) rated their hunting experience as very good or good. Also, most hunters (70%) approved of the preference-point system for the distribution of hunting licenses.

For the second consecutive year. a statewide black bear (Ursus americanus) harvest zone and quota system was utilized in 1991. 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. Separate harvest quotas were established for each unit, and a limited number of harvest tags issued. Each harvest tag allowed the taking of one bear that was not a cub. 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. A total of 4,936 hunters harvested 1,084 bear during the 1991 season. a 47 percent increase in the harvest from the previous year. Twenty-two percent of the hunters with a harvest tag were successful in 1991 compared to 20 percent in 1990. The composition of the harvest, 64 percent males, 34 percent females, and two percent bears of unknown sex, was similar to 1990 results.

A random sample of bear hunters was contacted after the 2006 hunting season to determine hunter participation, hunting methods, bear harvest, and hunter satisfaction. In 2006, an estimated 8,900 hunters spent nearly 60,700 days afield and harvested about 2,639 bears; an increase of nearly 20% from 2005. Statewide, 30% of hunters harvested a bear. Baiting was the most common hunting method used to harvest bears, although hunters using dogs had greater hunting success than hunters using bait only. Statewide, about 58% of hunters rated their hunting experience as very good or good. Most hunters (72%) approved of the preference-point system for the distribution of hunting licenses.

Hunters killed an estimated 1,391 black bears (Ursus americanus) in Michigan during the 1983 hunting seasons. An estimated 1,355 bear were killed during the three "early" bear seasons. The remaining 36 bear were taken during the bear season coinciding with the firearm deer season in the Upper Peninsula. Dogs were used to hunt bear during selected seasons. Of the estimated 1,391 bear harvested, 324 (23%) bear were taken with dogs. Male bears comprised 60% of the kill, females made up 37% of the harvest, and 3% of the kill were not sexed.

A survey of bear hunters was conducted following the 1998 hunting season to determine hunter participation, hunting methods, bear harvest, and hunter satisfaction.

For the fourth consecutive year, a statewide black bear (Ursus americanus) harvest zone and quota system was utilized in 1993. 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 1993, a total of 4,590 hunters harvested 1,292 bear during the 1993 season, a six percent increase in the harvest from the previous year. Twenty-eight percent of the hunters with a harvest tag were successful in 1993 compared to 27 percent in 1992. The composition of the harvest, 59 percent males and 41 percent females indicated an increase 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 1993 bear hunting experiences. Twenty-one percent of the hunters rated their bear hunting as "excellent", 17 percent as "very good", and 27 percent as "good". The season was rated as "fair" by 19 percent of hunters and "poor" by 16 percent.
