Start Collecting Data Today

Yes, it's that simple. You can start collecting today.  Below is a listing of protocol measurements that align directly to the campaign.

Protocols

Along with tree height measurements, the campaign will focus on using multiple data collection protocols to complement the tree height measurements.  It is recommended that students measure tree height with other protocol measurements, in order to allow for a more complete look into why trees play such an important role in our ecosystem.

What is a tree? A tree is a woody perennial plant, typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance from the ground.

  1. Trees measured should be at least 5m (16.4ft) tall; BUT, if a tree is newly planted and you want to track its growth over time, please feel free to measure it's tree height even though it may be under 5m tall.
  2. Trees measured should be isolated trees or the tallest trees in a large grouping of trees.
  3. In order to be able to best compare the GLOBE tree height data to the ICESat-2 tree height data, we recommend taking tree height measurements of many trees in one area.

Below is the recommended suite of protocols.

Main Protocol

Biometry Tree Height (CLICK HERE TO SEE THE TREE HEIGHT MEASUREMENT TUTORIAL SLIDES)

Complementary Protocols (Used as supplemental measurements as to why there might be changes in tree height over time)

Green Up / Green Down

Land Cover Classification

Carbon Cycle

Baseline Protocols (Used to establish the location environmental conditions at a study site)

Air Temperature

Surface Temperature

Soil Temperature

The objective of taking these protocol measurements is to allow for students to have multiple data layers to allow for inter-comparison of data that is relevant to measuring and understanding tree height.
