Many shorebirds breed in the Arctic tundra. It’s such an important ecosystem that every year, the National Oceanic and Atmospheric Administration issues an Arctic Report Card that details how the region has been affected by rising global temperatures.

Shorebirds that nest among low-lying tundra plants may soon find woody thickets encroaching on their breeding grounds, which could have ripple effects on shorebird populations around the world.
