Blue Trees

Sea level rise would threaten famous San Francisco landmarks including Boudin Bakery, Pier 39, Fisherman’s Wharf, and Baker Beach.

Blue Trees is a project to provide communciation prostheses to selected trees. The device has two way functionality; it allows the trees to report temperature and other environmental conditions, foliage and sap levels, and other environmental parameters to observers (terrestrial and extra-terrestrial); the tree also serves a bulletin board for other organisms to communicate to the tree and other observers.

The communication device consists of four bands of blue lights around the tree trunk. Under non-interactive interaction, the lights operate sequentially. Each elevation represents expected future sea-level rise for the specified city.
