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 survey conducted in 1998 and 1999 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 2000. 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 79% of the segments surveyed.
Report on fox populations and problems in the northern portions of Michigan.
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. In addition to this, unusually mild winter weather, attributable to the EI Nino climatological phenomenon, minimized survey opportunities during February and March. Thirteen of the 20 routes assigned were surveyed, and 10 of the 13 routes attempted were completed. The Western UP Management Unit completed all or most of 11 of 12 routes assigned. The Research Section completed two routes in the central UP, and the Eastern UP Management Unit completed 0 of 6 routes assigned. Therefore, the results of this survey in 1998 were derived only from the western two-thirds of the UP. Data acquired indicates that coyote (Canis latrans) and wolf abundance may have increased between years in the areas surveyed. Fisher, fox, hare/rabbit (Lepus americanus and Sylvilagus floridanus), and grouse abundance may have decreased, while marten and bobcat numbers showed little change.

This report presents estimates of trapper catch of some of Michigan's important furbearers for the 1980-81 trapping seasons. The estimates are generated from responses to mail survey questionnaires. Presented for comparison are the results of similar mail surveys conducted after the 1969-70 and 1970-71 seasons. 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), and coyote (Canis latrans). Estimates for beaver (Castor canadensis), river otter (Lutra canadensis), and bobcat (Lynx rufus), are available from mandatory registration counts.

This report presents estimates of trapper catch and estimates of pelt values of some of Michigan's important furbearers for the 1982-83 trapping seasons. Furbearer catch data for the last three trapping seasons is presented in this report; also listed is the number of trappers and average take per trapper for 12 species. 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).

Article overviewing the problems associated with the fox population.
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.
