Celebrate trees by joining the citizen science community in the 2021 Community Trees Challenge where Science is Better Together! During the Community Trees Challenge, GLOBE and GLOBE Observer are asking citizen scientists to observe, learn, engage, and create as they track their progress on the Community Trees Challenge Activity Tracker. You can choose as many or as few of the activities as you like to participate. Work together as a family, as a group of friends, or independently – it is up to you. By completing these activities, you will improve your science observation skills, enrich your understanding of trees as part of our landscape, learn why NASA studies trees, be a part of a NASA-sponsored citizen science project, as well as join a citizen science community. There are a multitude of ways to be creative in this year’s challenge. Plus, your observations of tree height contribute to a global database that is free and open so that anyone - scientists, students, communities, and citizen scientists - can conduct research.
