Every national park has a story written in rock, water, and wildlife. USGS scientists are helping tell it. Across many parks, USGS scientists study changing ecosystems, wildlife, water, and natural hazards. From tracking contaminants in aquatic food webs to monitoring glaciers, mapping river change, and studying how plants and animals adapt to changing conditions, this work helps us better understand these places and provides science and data to help park managers make informed decisions. Swipe through for a look at some of the USGS science happening in parks across the country and follow along this week as we highlight more USGS science in our national parks. 📷 1: USGS and NPS staff collecting data, Canyonlands National Park, Utah. For over 30 years, the USGS has been working with the NPS in Canyonlands to monitor plant cover and diversity, soils, and biological soil crusts to see how the dryland ecosystem is responding to changing conditions and past grazing. 📷 2: Bass Harbor ...
