The Hudson Valley is full of distinctions that make it one of the most special places in the world. From the oldest suspension bridge in the country to our stunning Shawangunk landmark, a lifetime is hardly enough time to enjoy them all. A recent scientific discovery, however, has elevated our corner of New York into another stratosphere.

The findings are so astounding that it's almost criminal that the data isn't common knowledge: the oldest known forest on the entire planet is right here in the Hudson Valley.

The Oldest Forest in the World Is in the Hudson Valley, NY

Scientists first investigated the site back in 2009 and published their findings in February 2020. While the global shutdown due to the COVID pandemic just one month later may have had something to do with the lack of news coverage, it's better late than never to appreciate one of the most impressive discoveries that's been made right here in our own back yard. But where is it?

The Oldest Forest in the World is Near Cairo, NY

Scholars specializing in the study of ancient plant life (called paleobotanists) now say that the oldest known forest in the world is in Greene County near Cairo, NY. The site, located in an abandoned quarry, contains rocks with fossils of tree roots that can be dated back 385 million years. Not only is the age of the site impressive, but these trees actually helped shape the future of the planet.

Trees that Changed the Planet Found Near Cairo, NY

The fossils point to the presence of a tree called Archaeopteris, a species that previously had been believed to be only (!) 365 million years old. The shocking discovery is helping prove that trees with large root systems began to evolve far earlier than originally believed. They also heavily influenced the climate, as they were some of the first plants to filter large amounts of carbon dioxide from the air.

Not only is it a badge of honor for the Hudson Valley to be the location for such a special discovery, but the scientific value is incredibly special as well. While the cradle of civilization may be on a different continent, this may be the literal birthplace of the planet's first trees. Check out some more "oldest" landmarks in New York below.
