Cougar Creek fifth graders analyze the impact of trees on their stormwater

measuring tree diameterStudents in Tiffany Dewitt's fifth grade class measured trees near the playfield and took the estimates back to their classroom as part of their Earth Day activities. Plugging in the type of tree and their numbers to the MyTree website, they were able to estimate how much water the trees pull out of the ground each year – helping to dry out their playfield during our wet winters.

One student estimated the alder tree he measured near the playground could take in more than 3,600 gallons of water in one year – or 72,000 gallons in 20 years!
