LTRR Outreach & Science Education

Our LTRR Outreach Program is the core of communicating science to a broader audience and serves as the “heartwood” of our science education program. It is through your support that we are able to deliver a top-notch outreach and science driven education program.  The LTRR Outreach Program centers on providing researchers, students and the public a unique hands-on opportunity to explore the applications and use of dendrochronology in a world class research setting. Each year, thousands of visitors ranging from preschool through retiree are enriched through interactions with our researchers, docent outreach team, one-of-a-kind exhibits, lab tours, classroom visits and the Sky Island Science Investigators field classes,  where children become the “scientists”. Your support is vital to educating the public as well as fostering the next generation of researchers.
