  • Bachelor of Science in Biology
    • Emphasis


    Environmental Biology & Ecology students have the opportunity to explore numerous public and private lands from the sagebrush and lush riparian "lowlands" to deep forests and rocky alpine crags. The land that surrounds campus, including six wilderness areas, is a vast and wild laboratory. On campus, students learn in an intimate and experiential classroom environment that promotes collaboration between students and faculty. 

    The Program

    The Environmental Biology & Ecology emphasis prepares students for an array of careers in environmental biology, including ecology, natural resources management, research and education. Starting their freshman year, students learn from biologists dedicated to hands-on, practical approaches to learning—all complemented by a liberal arts core and a strong basis in natural history.

    As students advance to upper-division courses, they develop experimental design and science communication skills, and hone field techniques such as species identification, vegetation monitoring, stream assessment, radio telemetry, spatial analysis (GIS) and diverse approaches to measuring populations, communities and ecosystems. 

    For students pursuing a graduate degree toward an environmental career, Western offers a 3+2 program where students complete a B.S. in Biology and a Master in Environmental Management (MEM) in just five years. Our MEM program boasts an 85 percent placement rate into environmental careers. 

    Careers & Opportunities

    Before Environmental Biology & Ecology students graduate, they have numerous networking opportunities with natural resources agencies, through internships, class work, field trips, temporary positions and volunteer opportunities. Due to our intimate educational experience, faculty are able to provide personal career advising with detailed references. Our graduates are often hired by local, state and national agencies including: 

    • Bureau of Land Management
    • Colorado Parks and Wildlife
    • National Park Service
    • Natural Resources Conservation Service
    • U.S. Fish and Wildlife Service
    • U.S. Forest Service

    Graduates also work with nongovernmental organizations, such as nonprofit environmental groups, Native American tribes, ecological consulting companies and for-profit consulting companies.
