Report on a survey done to estimate the number of trappers that used foothold traps and snares to catch fox or coyotes and determine their trapping effort and harvest of fox and coyotes. In addition, trappers were asked to report the types and number of animals besides coyote and fox that were captured in foothold traps and snares.

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.

This report presents estimates of trapper catch of some of Michigan's important furbearers for the 1981-82 trapping seasons. Presented for comparison are the results of similar mail surveys conducted after the 1970-71 and 1980-81 seasons. No mail surveys were conducted or estimates available during the nine year interim period because of rapidly increasing numbers of sportsman's license holders who were authorized to trap during that time period. The species included in this report are the muskrat (Ondatra zibethica), mink (Mustela vison), raccoon (Procyon lotor), opossum (Didelphis marsupialis), striped skunk (Mephitis mephitis), weasels (Mustela sp.), red fox (Vulpes fulva), gray fox (Urocyon cinereoargenteus), coyote (Canis latrans), bobcat (Lynx rufus), beaver (Castor canadensis), and river otter (Lutra canadensis).

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.

Report of the first case of heartworm (Dirofilaria immitis) found in a gray fox in Michigan.

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.

This report presents estimates of trapper catch and estimates of pelt values of some of Michigan's important furbearers for the 1983-84 trapping seasons. Presented is the number of animals trapped. average pelt price, and estimated total harvest values.

Results of a survey of furbearers in the Upper Peninsula, conducted in 1999. 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. Reliable and efficient methods to census these furbearers currently do not exist.

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.
