By Michael R. McHugh Winter Ecology Spring 2010 Mountain Research Station – University of Colorado, Boulder Colorado Moose will have similar behavior than other “Typical” Moose Objective: • Moose Background • Methods Used • Results • Winter Behaviors • Discussion and Conclusion Alces alces Moose are the largest members of the deer family • Females: 800-1100lbs. (CDOW, 2009) • Males: 900-1200lbs. (CDOW, 2009) Non-Native to Colorado • Introduced in 1978 near North Park (CDOW, 2009) Colorado is the southern edge of moose’s range Locating • Food Sources Willows and Saplings • Watering Areas Accessible • Bedding/ Tracks How old? Frequency • Talk to local Stride Length Bed Size Distance between Beds Overall Size of Bedding Area Clear Drag Snow depths had minimal impact Splitting between objects Trail Following Cow and Yearling were bedding in areas with heavy cover within ten feet of each other Bull was in open willows within 40 feet of closest bed Urine found in all beds Bed Sizes Small Groupings • Cows and calves are common social grouping • Bulls are not commonly part of this social grouping Moose Spotted "Typical Moose" Mother W/ Yearling Mother W/ Yearling and Bull Diet • Willow stems/buds, leaves, bark, and shrubs ~11 lbs. per day (Young, 2000) Habitat • Willow patches within marshy mountain meadows Moose Spotted "Typical Moose" Importance of Snow Dynamics • Snow density • Air and Snow Temperatures • Snow depth Adaptations • Cloven Hooves • “Yards” • Trail following Moose Spotted Snow Dynamics Used Trail Following "Typical" Moose Exact footing Yards This data can be used for the introduction of moose into other non native states Adaptations have been made by lower latitude moose I would like to look at behaviors during all seasons of the year Lundmark, Caroline, and John P.
