Scientist Tracks Trees Coming Back To Life WBZ - Boston,MA,USA
The network is called "PhenoCam," because the project is focused on "phenology"-- how the timing of the seasons affects plants and animals. "Images are sent out automatically to our image archive every half hour," said Richardson, "We have literally hundreds of thousands of archive images from the past several years." Since trees are so temperature sensitive, they are a good indicator of the arrival of spring and that timing can have implications for climate science.
