A priority of Yellowstone is to maintain healthy, functioning ecosystems: not just on land, but in the water as well. Yellowstone cutthroat trout are a major part of food webs in the park, but they have been in decline due to predation from introduced lake trout. That's why we put out more than 6,000 miles of gillnet each summer and catch hundreds of thousands of lake trout in order to reduce the long-term extinction risk and restore the ecological role of cutthroat trout. "If the Yellowstone cutthroat trout were to disappear, and we were to allow the lake trout to thrive within the lake, many of the animals that depend on the cutthroat trout would also be displaced or gone." - Native Fish Conservation Program Leader Todd Koel

Watching geysers and hot springs is one of the top reasons people come to Yellowstone. A common question we receive is, "How are the boardwalks built?" Well, there's a team of people who plan, build, and maintain the 15+ miles of boardwalks that lead you safely to the places you want to go. "It's one of those things people might walk right over without noticing, but the work our crew does helps millions of people safely see these fragile features up close without damaging them." - Boardwalk Crew Leader Paul Anderson

Yellowstone is the only place in the United States where bison (Bison bison) have lived continuously since prehistoric times. They exhibit wild behavior like their ancient ancestors: congregating during the breeding season, migrating, and exploring that results in the use of new habitat areas. For today's #WhatWeDoWednesdays, we will speak with Senior Bison Biologist Chris Geremia for a live Q&A about how we study the natural role of bison in the park.
