The Decline of Forests in the United States Over Time
This historical map visualization illustrates the dramatic reduction of forest cover in the United States between 1620 and 1920. The green areas represent forested regions, which significantly shrink over time due to colonization, industrial expansion, agriculture, and urban development.
1620: Before European settlement, much of the U.S. was covered in dense forests, especially in the East, Midwest, and Pacific Northwest.
1850: Deforestation accelerated due to westward expansion, timber harvesting, and land clearing for agriculture.
1920: By the early 20th century, large swaths of forests were lost, particularly in the Great Plains and Eastern regions, as industrialization and farming reshaped the landscape.
While conservation efforts and reforestation programs have since helped restore some forests, this map serves as a stark reminder of human impact on natural ecosystems and the need for sustainable environmental practices.
