Report of a survey 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 2009.

Report on why using a bobcat bounty is not the answer to solving scarcity problems among its prey.

A survey of furtakers was conducted following the 2001 hunting and trapping seasons to determine the number of participants, days afield, and furbearer harvests.

Report on the results of the 1993-1994 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.

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.

Pressure by concerned organizations and the Convention on International Trade in Endangered Species (CITES) has caused the Fish and Wildlife Service to compile comprehensive data on some furbearers. This documentation is necessary to verify the stability of populations and to justify continued harvesting and exportation of pelts. During the winter of 1981-82, the Wildlife Division undertook collection of hunter and trapper harvested bobcats (Felis rufus) in order to increase knowledge of this species and to evaluate possible field techniques for sex and age determination. The sex ratio of the bobcats examined from Region I was 41:28, males to females. The young-of-the-year percentage was down slightly from last year, but the age groups 0 to 3 years again made up over 80% of the total animals harvested and submitted. The yearling age class was greatest in occurrence. The sex ratio of the bobcats examined from Region II was skewed heavily towards males (20:7). This is a much higher figure than has been reported before. Over forty percent of the animals were young-of-the-year, and nearly 75 percent were in the age classes 0-3 years.

Report on the results of the 1990-1991 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.

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 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.

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.

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.

A survey of furtakers was conducted following the 1997-2000 hunting and trapping seasons to determine the number of participants, days afield, and furbearer harvests.

Pressure by concerned organizations and the Convention on International Trade in Endangered Species (CITES) has caused the Fish and Wildlife Service to compile comprehensive data on some furbearers. This documentation is necessary to verify the stability of populations and to justify continued harvesting and exportation of pelts. During the winter of 1982-83, the Wildlife Division collected bobcats (Felis rufus) from hunters and trappers to increase the knowledge of this species, and to evaluate possible field techniques for sex and age determination. The sex ratio of the bobcats examined from Region I was 100:82 (33:27), males to females. The percentage of young-of-the-year submitted was down for the second year in a row. falling from 40% in 1980-81, to 35% in 1981-82, and to 30% in 1982-83. The age groups 0 to 3 years for the third year in a row made up nearly 80% of the total animals submitted. The sex ratio of bobcats examined from Region II was moderately skewed toward males: 100:65 (20:13). This was fairly consistent with the previously mentioned studies, but was considerably less than last year's ratio 100:35 (20 males:7 females). Only 18% of the animals were young-of-the-year, with age groups 1 to 6 years being nearly equally represented in the sample (9-15%).

Report on the results of the 1986-1987 Bobcat Survey. Pressure by concerned organizations and the Convention on International Trade in Endangered Species (CITES) has caused the Fish and Wildlife Service to compile comprehensive data on state furbearers.

A sample of furtakers was contacted after the 2003 hunting and trapping seasons to estimate the number of participants, days afield, and furbearer harvests. In 2003, about 13,000 furtakers pursued furbearers, an increase of 7% from 2002. The species most frequently pursued by trappers were raccoons, coyotes, and muskrats. Hunters most commonly sought coyotes, raccoons, and red fox. Harvest levels of most furbearers in 2003 were within historical ranges, except for harvest of muskrats and raccoons. The number of muskrats taken by trappers was the lowest recorded since 1957, and the number of raccoons taken by hunters was the lowest recorded since 1980. Trends in harvest are affected by both changes in furtaker and furbearer numbers; thus, harvest per furtaker was also examined for trends. The mean number of raccoon and opossum taken per furtaker has increased since the 1980s. The mean harvest of coyotes per hunter has increased since the mid-1980s, while the mean harvest of red fox by both hunters and trappers has declined during this same period. These trends suggest that raccoon, opossum, and coyote may have been increasing in abundance during the last 20 years, while red fox numbers may have been declining. An estimated 24% of trappers attempted to catch coyote or fox using snares, and 8% of trappers tried to catch beaver using snares set underwater. About 4% of bobcat hunters hired a guide to assist them while hunting bobcats. Nearly 59% of bobcat hunters used calls while hunting bobcats, and 45% of bobcat hunters used dogs.
