Wildlife biology · NEPA · Conservation easements
Wildlife expertise. Practical solutions. Better projects.
Prairie Sky Ecology is an independent ecological consultancy in the Denver area. Principal Kim Cornelisse brings wildlife biology, NEPA experience and careful field science to land trusts, agencies and project teams across Colorado and the Rocky Mountain West.
What we do
Three kinds of work, one standard of care.
Conservation easements
Baseline documentation reports, annual monitoring support and conservation values assessments for land trusts, conservancies and landowners.
Easement services →Wildlife biology & field surveys
Threatened and endangered species, migratory birds, habitat assessments, wildlife crossings and CDOT Section 240 nesting-bird compliance.
Wildlife services →NEPA & environmental planning
Environmental Assessments, Environmental Impact Statements, Biological Assessments and the agency coordination that gets them through.
NEPA services →Experience
Science that supports decisions.
More than ten years as a wildlife biologist and special-status species preparer on some of Colorado's most significant environmental studies, with firms including URS (now AECOM) and Tetra Tech.
Transportation
CDOT and RTD corridor studies, including US 160, US 550 and the US 36 FasTracks EIS. Wildlife-crossing recommendations that were built.
Water
Denver Water's Moffat Collection System EIS, the Rueter-Hess Reservoir EIS and the Southern Delivery System Draft EIS.
Energy & public lands
BLM oil-shale research EAs in the Piceance Basin; National Park Service EAs and EISs in Washington State.
Agency coordination
BLM, USFWS, NPS, USACE, CDOT, CPW, SHPO, counties and municipalities, Denver Water and private energy clients.
From field data to project decisions
Assess → Analyze → Advise → Solve
Successful environmental work takes more than identifying impacts. It takes practical, defensible solutions that work for the client, protect ecological resources and meet regulatory requirements.
Looking ahead
Modern tools, expert judgment.
Prairie Sky Ecology brings GIS, remote sensing and emerging AI tools into the work where they sharpen field data and make decisions clearer and better supported. Technology augments the biologist; it does not replace her.
