Course Description
Syllabus for printing

Wintertime offers insights into the natural history of organisms and function of ecosystems that are not often appreciated in summer visits to the field.  Winter Ecology is a survey of physical and biological processes and their interaction in wintertime snow-covered environments.  Through classwork, fieldwork, and individual projects, we will focus on the dynamics of high-elevation ecosystems in the western US.  Based out of the CU Mountain Research Station's year-round Science Lodge, we will spend 6 weekends exploring the ecology of upper montane, subalpine, and alpine landscapes in winter. We will study plant, vertebrate, and microbial adaptations to winter and the dynamics of terrestrial, aquatic, and snowpack environments.  We will consider how winter processes play a role in “growing season” dynamics, shape landscapes, and are important factors in conservation and management of natural resources of the Rocky Mountains.

    Instructor's Goal
    “A personal goal for me, as an instructor, [is] to foster familiarity with the nature of science.  There are many facets to understanding the world of science.  One is experiencing the process of accumulation and evaluation of scientific understanding – how do new ideas arise and how are they tested?  Another is developing the ability for independent thought, to be able to generate innovative ideas and [to] critically assess the results of others.  And finally, gaining what is often called a ‘sense of place,’ which is to say in this context, to start on the road to develop an intuitive, personal sense of how natural systems work.” 

                  – T. Kittel (Center for Environmental Research & Conservation Notes, Fall 2000, Columbia University, NY)

    • “Hands down the best class ever taken at CU.”  (Spring 2011)
    • “The Winter Ecology Field Course at CU Boulder's Mountain Research Station is like no other ecology course. Covering a wide range of topics, from climate to small mammals’ winter ways to plant distribution, it was a wonderful way to experience winter research conditions and a great introduction to ecology, from a winter perspective.  I would say prepare to work hard, and say ‘I didn't know that!’ a lot.”  (Spring 2005)
    • “There are few ways to get the hands on experiences a field course provides.”  (Spring 2005)
    • “The field exercises were great!  Everyone should take a course like this.”  (Spring 2006)
    • “I also really love the small class environment. It’s really cool to go out into the field and take samples, cook dinner, and play card games together. This class is a bonding experience like none other. Lectures aren’t really lectures; they’re more like conversations with individuals who know a lot more about this stuff than I do.”  (Spring 2013)

    • “Outside time was fantastic.  Being able to talk about a subject and then go study/observe was crucial.  Field courses are great and should be required for all physical geography students.”  (Spring 2005)
    • “Expect to learn new things with fun people.  I thought this class was great.  Out of [my field courses], this was definitely my favorite field class.  ...   A really great experience!”  (Spring 2005)
    • “The format was great mixing lecture, field, guest lectures, etc.”  (Spring 2005)
    • Guest field instructors were all awesome.  The 'expert of the day' made the class great.  Do it  Do it  Do it!”  (Spring 2010)
    • “Tim is an excellent prof.  He will excite your interest and encourage you to learn immense amounts about winter ecology.”  (Spring 2005)

    • “Be ready for snow & cold, 10-20 other friends, and a beautiful environment”  (Spring 2010)
    • It kinda sucks giving up your weekends, but it is completely worth it.”  (Spring 2010)
    • “It is a great course, pay attention, and put the effort in.”  (Spring 2010)

    Health Matters
    Most fieldwork will be in high elevation, snow-covered, and/or wind-blown areas.  Students must come prepared to do wintertime fieldwork under such conditions (see Required Equipment).  Participants need to be in good health and physical condition and aware of the physical stress of being out in high-elevation wintertime environments, including low oxygen, high exertion, and cold temperatures – those with respiratory or heart conditions are advised to consult their physician before enrolling.

    Required Personal Equipment
    Equipment required for field work includes, in the minimum:
    • Backcountry skis (telemark or touring) with climbing skins, or snowshoes (with sufficient floatation on unpacked snow and grip on packed/icy surfaces)
    • Extreme cold weather clothing and boots - sufficient to stay warm while standing about for substantial periods (e.g. 1 hr),
    • Ski goggles, skiing face mask or balaclava, day pack, ...

    University Course Policies –

    In and Out of Classroom Behavior

    Students and faculty each have responsibility for maintaining an appropriate learning environment. Those who fail to adhere to such behavioral standards may be subject to discipline. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, color, culture, religion, creed, politics, veteran’s status, sexual orientation, gender, gender identity and gender expression, age, disability, and nationalities. Class rosters are provided to the instructor with the student's legal name. I will gladly honor your request to address you by an alternate name or gender pronoun. Please advise me of this preference early in the semester so that I may make appropriate changes to my records. For more information, see the policies on classroom behavior and the student code.
