Adopt a Canopy
Created by John Pickle, DEW Educator, Arlington, MA
Every spring and summer, deciduous trees develop and expand new leaves. In the fall, the leaves change color and fall to the ground, starting the cycle again. Taking photographs weekly or monthly and over the years can reveal much about the timing, known as the phenology, of these events as well as the health and fullness of the forest canopy.
- Locate your Picture Post to get a good view of a single tree or a group of trees of interest.
- When you take pictures, the date of each picture is stored in the camera and uploaded to the Picture Post database when you upload your photographs.
- Try to take pictures during the same time of day to keep the light angle as constant as possible.
- Place an object of known size in the picture to use as a scale.
- Use the DEW software to measure percent leaf cover and monitor the health of the canopy.
