A survey was completed to determine the number of people hunting and trapping bobcats in Michigan, the number of days spent afield (effort), and the number of bobcats registered. Estimates derived from harvest surveys, as well as information from mandatory registration reports, field surveys, and population modeling are used to monitor bobcat populations and establish harvest regulations.

Report on the results of the 1999-2000 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.

At the end of the 1993-94 furharvester seasons 755 license buyers were mailed a questionnaire asking for the results of their hunting and trapping efforts. Those who failed to respond to the original mailing were sent up to three reminders. A total of 516 questionnaires were returned for an adjusted response rate of 72 percent. The number of Fur Harvester licenses sold was below 10,000 for the first time since the license was issued in 1986. An estimated 7,680 individuals (78%) hunted or trapped furbearing animals using one of the three license types. Approximately three fifths of these individuals (4,686) used traps while 5,163 hunted furbearers. The majority of raccoon, coyote, and bobcat were taken by hunters, while trappers took a greater number of opossum, skunk, weasel, and fox. The only legal means of take for muskrat, beaver, otter, fisher, and badger is trapping. Harvests of all species except otter were lower than 1988-89 estimates.

Each state has been requested by the Fish and Wildlife Service and the Convention on International Trade in Endangered Species (CITES) to compile comprehensive documentation of their furbearing populations. During the winter of 1980-81, the Wildlife Division undertook collection of hunter and trapper harvested bobcats (Lynx rufus) in order to increase knowledge of this species. Skinned bobcat carcasses were obtained from collectors throughout northern Michigan and the following determinations made: sex, age, weight, physical condition, stomach contents, parasites present and reproductive history. This information was tabulated and the data summarized for each region.

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 1998-2000 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. Routes were surveyed 1-3 days after a marker snow, and data from 11 furbearers and 5 other species of interest were collected. Marten tracks were found along 48% of the segments surveyed in 2001. The coyote (Canis latrans) was the most widely distributed furbearer, leaving tracks along 78% of the segments surveyed. The Lagomorphs (snowshoe hare, Lepus americanus and cottontail rabbit, Sylvilagus floridanus) were the most widely distributed species group, being detected along 75% of the segments surveyed.

Past estimates of the ages of bobcats (Lynx rufus) have been made counting cementum annuli in canine teeth. However, a canine tooth is impractical to remove from a live-trapped bobcat, and its absence may significantly reduce the fitness of the animal after release. The purpose of this study was to determine the feasibility of using cementum annuli counts from alternate teeth for bobcat age estimates. Attempts to extract both upper and lower tooth rows from bobcat carcasses revealed that lower incisors would be the only teeth readily extracted from anesthetized bobcats. The lower third incisors can be used effectively in situations where canine teeth are impractical to remove.

At the end of the 1988-89 fur harvester season 1,980 license buyers were mailed a questionnaire asking for the results of their hunting and trapping efforts. In 1988-89, the numbers of both hunters and trappers were down from the previous season. The number of individual trappers (6,700) declined 41 percent compared to last year, while the number of hunters (7,650) pursuing furbearers dropped 30 percent. This was the first time since the issuance of furharvester licenses (1986) that hunters outnumbered trappers. Three years of trapping/hunting responses from past fur harvest questionnaires indicate that the majority of raccoon, coyote. and bobcat are taken by hunters, while trappers consistently take a greater number of mink, opossum, skunk, weasel, and fox. The only legal means of take for muskrat, beaver and otter is trapping. In general, fewer trappers took fewer numbers of furbearers during the 1988-89 seasons compared to the previous year: only increased numbers of beaver, weasels, and coyotes were trapped. Decreased harvest was also reported by hunters. The only significant increase in harvest was recorded for gray fox: although hunter rates of weasels and bobcat were up slightly.

A survey was completed to determine the number of people hunting and trapping bobcats in Michigan, the number of days spent afield (effort), and the number of bobcats registered. In 2007, 4,058 people obtained a bobcat harvest tag valid for the hunting and trapping seasons. About 61% (2,462) of these tag-holders attempted to hunt or trap bobcats, and 23% of these furtakers registered at least one bobcat. An estimated 1,805 people attempted to hunt bobcats and spent 19,096 days hunting and registered 340 bobcats. Nearly 850 people attempted to trap bobcats and spent nearly 24,848 days trapping and registered 320 bobcats.
