POSTPONED - Trees Challenge 2020: Make Every Tree Count
To celebrate the 50th anniversary of Earth Day and the 25th anniversary of the GLOBE Program, GLOBE Observer is hosting a month-long citizen science challenge in April 2020. Volunteers are invited to measure the height of as many different trees as possible throughout the month using the Trees tool in the GLOBE Observer app. The individuals, schools, and registered teams that measure the most trees will be recognized as top observers in the challenge.
