Science at Yellowstone National Park

Yellowstone: A Living Laboratory

Yellowstone National Park uses science across disciplines to inform management, protect resources, and advance knowledge.

Ecological Research

• Wolf reintroduction (1995) → trophic cascade studies (elk behavior, willow/aspen recovery, beaver, songbirds).
• Grizzly bear population monitoring (DNA hair snares, GPS collars).
• Bison genetics, brucellosis, migration.
• Invasive species (lake trout, cheatgrass) impacts.

Geothermal Research

• Monitor 10,000+ thermal features (geysers, hot springs, fumaroles, mudpots).
• Geyser prediction models (Old Faithful ±10 min).
• Hydrothermal explosion hazard assessment.
• Microbial extremophiles (thermophiles) → biotechnology, origin-of-life insights.

Wildlife Management

• Population surveys (aerial, camera traps).
• Habitat use modeling (resource selection functions).
• Disease surveillance (CWD, brucellosis, plague).
• Human-wildlife conflict mitigation.

Hydrological Research

• Watershed monitoring (Yellowstone, Snake, Madison rivers).
• Water quality (thermal, chemical, sediment).
• Groundwater-surface water interaction in geothermal areas.
• Climate change impacts on snowpack, runoff timing.

Climate Change Research

• "Sentinel site" for NPS Climate Change Response Program.
• Temperature trends (+1.5°C since 1950), earlier snowmelt, longer fire season.
• Species range shifts (pika, whitebark pine).
• Adaptation planning (assisted migration, fire management).

Paleontology

• Eocene fossils (petrified forests, early mammals) in volcaniclastic rocks.
• Quaternary fossils (mammoth, bison, camel) in lake sediments.
• Trace fossils in thermal areas.

Visitor Use Science

• Carrying capacity models (traffic, parking, trail erosion).
• Social science: crowding perception, satisfaction, economic impact.
• Education/interpretation effectiveness evaluation.

Science ensures Yellowstone remains "for the benefit and enjoyment of the people" — sustainably.
