North America
Most important big game animal
30 subspecies
Exist over entire North American Continent

activities of immigrants
◦ 1900: 500,000
◦ 2000: 30 million

◦
Minnesota
◦ Existed primarily in southern Minnesota where food
and cover are available
◦ Deer did not originally live in evergreen forest
◦ Forest lands became attractive after cutover and
regrowth from forest fires
◦ Overpopulation occurred early in 1900’s
Habitat over browsed
Consumed entire food source
15-20 deer per square mile
◦ 1850-1900 deer marketed commercially
Deer meat sold in markets
St. Paul customers purchased 8-10 cents/pound
1872: 6 tons shipped to Boston from Litchfield
Unlimited harvest
◦ Before 1897, no restrictions and no hunting license
required
1900: Harvest limit 5, license cost $.25
1901: limit 3
1905: limit 2 and a 21 day season established
1915: limit 1
1920s: bucks only law and alternate year
1933: every year hunting
Today the population is growing
◦ Deer management units established
◦ Present status
Deer over entire state
Hunting season is annual
Approximately 2 million deer exist in Minnesota
Always present
Live primarily in western United States
Rocky Mountain species most common
No breeding colony currently exist in
Minnesota
Largest most distinctive mammal
Northern wilderness
A boreal (northern) forest mammal
Most common big game mammal before
lumberjacks
◦ Food for lumberjacks, early pioneers
◦ Loss of habitat
◦ White tailed deer competition
By 1885 Minnesota moose population scarce
First protection laws 1887
Current Minnesota population <10,000
“White Rump”
◦ Wapiti
American Sioux Indian Name
Native to Minnesota, very abundant
Elk disappeared by 1900s
◦
◦
◦
◦
Fenced pastures
Market hunters
Food source
Canine teeth valued
1932: small Minnesota herd found
Restocking effort
◦ Enclosure of 54 elk (from Jackson Hole, Wyoming)
◦ Superior National Forest (a few released)
◦ Beltrami County herd of 27 (from Itasca State
Park)
Common in Northern Minnesota
1660-1880 reported as abundant
Require large forested, muskegs (acid soil)
and bog areas
Two species
◦ Tundra reindeer
◦ Woodland caribou
By 1880s population diminished
◦ Unrestricted hunting
◦ Logging, mining, forest fires
◦ Settlement of land
Last Minnesota caribou sighted in 1940
Lasting hunting season was in 1904
Reintroduction of caribou to Minnesota in
1938 failed
Last reintroduction attempt: 1970-1980
Occupied North America from Appalachians
to the Rocky Mountains
2 species
◦ Plains
◦ Woodland
Fed and provided the Indians well
75 million existed at one time
Decline occurred within 30 years
◦ Due to white settler slaughter
Prairie regions of Minnesota
◦ Supported large herds
Plains bison
1850s bison disappeared from eastern
Minnesota
◦ Woodland
1880 4 animals were found in Twin Valley
Buffalo skulls were used by surveyors plotting
SW Minnesota
◦ Section corners – 4 skulls
◦ Half sections – 1 skull
◦ Readily available – early 1870s
Original range – western Minnesota
◦ On eastern edge of their range
Never abundant in Minnesota
Last hunting season – 1892
A native of America
Inhabited almost all of Minnesota
Migrated north due to settlers
Black bear most common species
Black bear disappeared from agricultural land
areas
White Bear Lake, MN
Were considered a nuisance
First laws to protect bear in 1917 were soon
repealed
◦ Bounty killing established in 1945
◦ Bounty killing eliminated in 1965
Tourist attraction
1971: first hunting season established
Separate permit required
1981: 1500 bear harvested
Bear management units established
Most current census has 15,000 Black bear in
Minnesota
Nuisance problems beginning again
Primary predator of deer and moose
Influence on population varies greatly
Consume about 15 adult deer per wolf
Prey on very young, old, weak, sick prey
Continuously hunting
Deer make easy prey in winter
Located primarily in the Superior National
Forest
Numbers declined from 1849-1965 due to
bounty payments
In 1967, wolves were listed on Minnesota
endangered species list
In 1975, management programs installed by
US Fish and Wildlife Services
Eastern Timber Wolf Recovery Team
established
Predator control program
10-30 verified livestock losses
Currently over 3000 wolves in Minnesota
Kill deer, but do not seriously affect
population
Prefer smaller game mammals
Primarily live in northern forested areas
Fox
Coyote
Raccoon
