Results of survey completed to determine the number of harvest tag holders who set traps for marten and fisher, the number of animals caught, types of traps used, and number of days spent trapping in 2010.

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 on the results of the 2001 American Marten Survey. The American marten (Martes americana) historically was found throughout Michigan. Extensive logging and uncontrolled trapping pressure eliminated them from much of their native range. Restoration of martens to suitable habitat began in the mid-1950's with wild animals obtained from Ontario. The restoration efforts were successful, and in March 1999, the marten was removed from the state's threatened species list. In 2000, it was determined that the marten population had become sufficiently abundant to allow a limited trapping season.

Results of a survey completed to determine the number of furtakers who set traps for martens, the number of martens that they caught, the types of equipment they used, and the number of days they trapped.

Report summarizing the characteristics and habitat needs of the pine marten, the process of the initial reintroduction and release, and suggestions for future releases.

The survey in this report was designed and conducted at the request of the Furbearer Management Workgroup of the Wildlife Bureau. It was designed to assess the current distribution and abundance of the marten across its potential range in both peninsulas, and to provide timely information for the management of this species in Michigan.

Report on the results of the 2002 American Marten Survey. The American marten (Martes americana) historically was found throughout Michigan. Extensive logging and uncontrolled trapping pressure eliminated them from much of their native range.

The restoration efforts were successful, and in March 1999, the marten was removed from the state's threatened species list. In 2000, it was determined that the marten population had become sufficiently abundant to allow a limited trapping season. In 2002 the regulations were unchanged.

Results of survey completed to determine the number of harvest tag holders who set traps for marten and fisher, the number of animals caught, types of traps used, and number of days spent trapping.

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.
