Instructions and Guidelines for Volunteers
Volunteering is simple. Take photographs with a camera or smartphone, collect data and complete the input form to submit your tree capture to the Last 6,000 Action Database. If possible, to help us identify the species of your tree, get a photograph of the leaves or needles and the whole tree.
We ask you to provide your best estimation of the tree's trunk diameter at breast height (DBH), species and current health. For tools and information to help in making a good estimation, check out the buttons below.

Tips for Trees on Private Property
It is considered trespassing to enter private property without the permission of the person living there. So, we recommend that you don’t enter private property to photograph or measure a tree’s diameter without speaking to the owner first. You should feel free however, to take a photograph of a majestic tree on private property from a public space like a sidewalk, street or public alley.
