Trees provide us with oxygen, shade, and that calming rustle on an evening hike. Now, they’re also providing the opportunity to do some citizen science! Here is SciStarter‘s round-up of tree-related citizen science projects that you can go out on a limb to participate in!
OPAL Air Survey Help scientists learn more about air quality throughout England by recording lichens on trees and looking for tar spot fungus on sycamore leaves. Get started!
Leafsnap This free mobile app uses visual recognition software to help you identify tree species from photographs of their leaves. Get started!
Redwood Watch Take photographs of redwood trees and submit them to researchers. Your data will help researchers understand where redwoods survive and help track redwood forest migration over time. Get started!
PhillyTreeMap PhillyTreeMap uses the iTree software from the USDA Forest Service to calculate the environmental impact of the region’s urban forest. Get started!
Join the SciStarter team and scientists who are also Washington Redskins Cheerleaders at the Smithsonian Air and Space Museum on Saturday 9/14 and get involved in Project MERCCURI!
