Scientists map more than 200 years of nature’s progress

AI Insight

Scientists are using modern technology including trail cameras and artificial intelligence to retrace Lewis and Clark's early 1800s expedition route across America. The project aims to document and compare current wildlife populations and distributions with historical observations recorded during the original 1804-1806 journey. This large-scale effort leverages a national research network to create a comprehensive assessment of how North American wildlife has changed over approximately two centuries.


Understanding long-term wildlife population changes provides crucial data for conservation planning and biodiversity management. This historical comparison can reveal which species have thrived, declined, or shifted their ranges due to human development, climate change, and habitat modification over the past 200 years.


Armed with trail cameras, artificial intelligence, and a powerful national research network, scientists are revisiting Lewis and Clark’s legendary journey to see how America’s wildlife has changed over the past 200 years.
