A champion tree is one that is considered the largest of its species. Species vary in size, height, and growth patterns. Trees grown in an open environment will have a larger crown than those grown in a forest. Every year people search for America's largest trees, bringing awareness to their beauty and ecosystem services, and fostering a desire to protect and preserve them for future generations.
The LGC is planning to gather information about these large and old trees in our hamlets.  If you think that you live with a champion or have seen one of these trees in your visits to Lewisboro's many parks and preserves help us to collect the data by following the steps below.
Step One:
Check out a Citizen Science Kit from the Lewisboro Library to measure your tree. You can also read about how to measure for Champion Trees on the New York Restoration Project Website by clicking below and following the steps

Step Two:
After collecting the data , use the Clifton Park Tree Age Calculator to calculate the age of your tree.
