2021 Community Trees Challenge

Science is Better Together

Who can participate:

Everyone!

Students and teachers at all grade levels, informal educators, and the public in GLOBE countries.

While getting out and taking observations might not be possible for everyone, this challenge provides multiple ways to participate and learn all about trees.

13 of 36

How to participate:

Observe, learn, engage, and create as you track your progress on the Trees Challenge activity tracker. You can choose the best journey for your interests or try to complete all the activities. Work together as a family, as a group of friends, or independently.

14 of 36

Always follow guidelines from your local officials, and only participate in GLOBE activities or use the GLOBE Observer app if it is safe to do so.

Engage about trees

As you complete activities or take observations, share your results with us through social media using #TreesChallenge or by tagging the GLOBE Program.

  • Find a special tree and share what makes it special using #TreesChallenge. You can read about some examples of special trees in the blog post "What in the World are Moon Trees?"
  • Ask an expert a question about trees. For example, talk to a tree scientist or arborist, or visit a nearby garden center or nursery and ask questions about trees local to your area. You can also join us on Thursday, May 6th at 2:00 pm EDT/18:00 UTC for a Reddit "Ask Me Anything" event on the r/AskScience channel, cross-posted to r/NASA .
  • Make a short video about why trees are important and share it using #TreesChallenge.
  • Follow GLOBE on social media

MULTIPLE WAYS STUDENT, EDUCATORS, AND CITIZEN SCIENTISTS ARE MEASURING AND OBSERVING TREE HEIGHTS, FROM THE GROUND UP

ONE WAY TO MAXIMIZE ACCURACY OF THE GLOBE TREE HEIGHT DATA IS TO TAKE TREE HEIGHT OBSERVATIONS WITH A HAND-HELD CLINOMETER AND THE NASA GLOBE OBSERVER TREES TOOL, THEN COMPARE THE MEASUREMENTS AND REPEAT!

The Hand-Held Clinometer for Measuring Tree Height

Clinometer: an instrument used for measuring the angle of elevation of slopes. A clinometer can be used to measure the heights of trees, poles, towers, and buildings. Get the clinometer at https://bit.ly/3akZJCG

The NASA GLOBE Observer Trees Tool for Citizen Science allows citizen scientists to take tree height measurements, information that can be compared with data from NASA missions.

An Example Observation of the NASA GLOBE Observer Trees Tool

The 4 most important things to remember:

  1. Only take NASA GO observations if it is safe and legal to do so.

  • When choosing a tree, make sure you can see the base and top of the tree and be able to walk to its base in a straight line with no obstacles.

  • Always keep your cell phone’s camera at eye level when measuring the angles to the base of the tree and the top of the tree.

  • Always make sure you have the correct height for the current observer taking the tree height observation - you can check this in the Trees Tool Introduction section.

Tree Height Comparisons: Hand-Held Paper Clinometer vs. NASA GO Observer: Trees Tool

By taking observations with the hand-held clinometer and the NASA GO Trees Tool, you can compare the various methods of tree height observations and practice data accuracy.

Taking great measurements and observations of tree height is vital to the accuracy and precision of the science, to the comparison of the data to that of ICESat-2 and GEDI, and to the understanding of local to global impacts of trees on the environment.

Our Challenges to You!

If safe to do so, take as many tree height observations as you can from 15-April 2021 through 15-May-2021. This will help with data density of tree height observations and will greatly help student and professional researchers compare the ground-based NASA GLOBE Observer tree heights to the NASA satellite/instrument tree heights!

After you take a NASAGO Tree Height observation, while still standing at the tree, please take a NASAGO Land Cover observation. This will allow for us to understand the environment in which the tree thrives, give us an upward look at the tree’s canopy, and a downward look at the ground surface and potential root system.

If it is not safe to go outside and take tree height observations, please visit the 2021 Trees Community Challenge website and check out the many GLOBE and NASA resources and activities. Also, you can visit the GLOBE Trees Family Guide website as well for great extension activities.

GLOBE Trees Family Guide

The GLOBE Trees Family Guide is a place to learn, with family and friends, all about trees. On Earth, there are approximately 3 trillion trees, each of them vital to our planet.
