Volunteers lean over to plant trees in grassy area of a forest in Hawai'i. These trees provide crucial habitat for native birds within the refuge.

The white rod with the barcode is a digital elevation rod that a leveling gun reads to capture the elevation of whatever point the rod rests on. We measure elevation levels at reservoirs to make sure our sensors are reading correctly in relation to an assigned elevation datum.

Example of a brown treesnake (Boiga irregularis) wrapped around two wires. This image is an example of how adult brown treesnakes can bridge power lines and cause power outages. The brown treesnake is an arboreal invasive species on Guam where researchers have discovered electrocuted snakes on power lines and at substations.
