california state parks
When a tree is slated to be cut down, a ribbon is tied around the trunk to tag it. Using that same symbol, we would place 70 native California birch trees in public plazas in California cities, each with a ribbon tied around it with the name of one of the parks slated to be closed. A QR code on the ribbon would allow you to donate to that park, and as each goal is met and each park is saved, the ribbon on the tree would be removed.
The corresponding website would have its own, digital forest that you could virtually "walk" through, clicking on each ribbon to bring up a description and photos of each park, and a link to donate directly to that park.
Additional ribbons would be wrapped around streetlights and road sign poles all around California, bringing you to the mobile site, where you can choose a park to donate to, or donate to the project in general.
