Results from the research of the research team, led by Dr. Darrel Jenerette, and the Earthwatch Urban Resiliency Program. Data from Operation Healthy Air is currently being analyzed and findings will be posted soon.
Resilient Trees 3.0 (January 2017-June 2017)
This current project will continue to build on the groundwork laid out during Resilient Trees 1.0 and 2.0 (below) by finding and measuring trees from a new set of 10 common urban tree species. Check our “Get Involved” section to find out how to join our current efforts!
Resilient Trees 1.0 (July 2015 – May 2016) & Resilient Trees 2.0 (June 2016-December 2016)
Working with citizen scientists, nonprofit partners, and institutions across a study area spanning from the beaches to the desert, this project was designed to find and measure healthy individuals from 20 specific tree species across this 150 mile-long climate gradient.
Operation Tree Canopy: NASA Project (August 2014 – August 2015)
During this project, citizen scientists and partners of the Earthwatch Urban Resiliency Program collected leaf samples from 122 different tree species in the 43 parks surveyed. This includes many iconic native species such as the native oaks (coast live oak, Engelmann oak, and valley oak), as well as many exotics. California sycamores, Chinese elms, coast live oaks, and jacarandas were found in close to 50% of the parks surveyed, but many species were found only in a small number of parks.
Scientists from Dr. Darrel Jenerette’s team have published several scientific articles using the results from the Earthwatch Urban Resiliency Program. These articles show the contributions of citizen science to research.
