Rosa the Ponderosa Pine lives in the Black Hills of South Dakota, is 24” diameter at breast height, and stands roughly 60 feet tall. From a seedling in 1281, Rosa is 738 years old and has provided a multitude of information on historic climatic patterns from the 13th century through the 20th century. Rosa’s location is not disclosed to protect her from vandalism. She was sprayed with insecticides to protect her from the worst of the mountain pine beetle (Dendroctonus ponderosae) epidemic that began in the Black Hills in 1997 and is still active. Frank Carroll has worked closely with Rosa during his time with the Forest Service and is intimately familiar with her value as a living treasury of our history. Shelley Deisch, State of South Dakota Division of Wildlife, first cored Rosa in the 1980s as a graduate student working on a climate study that used tree rings as indicators of drought.
Rosa is a living testament to how tough trees can be and provides important insight into all of the environmental factors trees must deal with to survive. Rosa embodies the American spirit of resiliency and enduring tough obstacles and adverse circumstances. We have a lot to learn from this great American tree that has been there through all of our history as a Nation and for so much of history of the Black Hills. Rosa watched General Custer ride through the Hills in 1874. She witnessed Crazy Horse and so many other heroes of the Hills through time. She stands today, a silent but watchful sentry over centuries of forest management, wildfires, insect attacks, and climate change.
