What Your Donation Supports

When you donate, you play a direct role

in our on-the-ground conservation and advocacy work. 

Here are a few examples of the kind of important efforts your support makes possible.

Close Up

Fund a video
to get the word out

We aspire to produce videos to spread the message about why mature trees are critical and to train new volunteers. High school groups are eager to help - but funds are needed.


Tools for Tree Inventories

Inventorying trees is important to knowing how best to protect them, but we can't gather the data without tools such as clinometers, diameter tapes, safety vests, and measuring wheels.



Getting the word out means printing costs, waterproof paper, signs, and many other expenses that quickly add up.
