"The Sacramento Tree Foundation has come up with a novel way to manage wood waste from the urban forest. Through a program called Urban Wood Rescue, dead trees that normally would be chipped into mulch or sent to a landfill to decompose are turned into slabs of quality kiln-dried wood prized by artisans and do-it-yourselfers."

After watching an online training, you are invited to participate in monitoring Sacramento's elm trees for Dutch elm disease while out on a walk or bike ride. You'll report your findings through a smartphone app so we can save our remaining iconic elm trees from this deadly disease.
