The spread of invasive, non-native marine algae is one of the greatest threats to Hawai'i's coral reefs and near shore marine ecosystems.

Alien algae have invaded
nearly 200 acres of Maunalua Bay.

Sediment and nutrients running from the land create an environment for the invasive algae to flourish.

And without enough fish to graze on the algae,
it grows unchecked.

As invasive alien algae spreads,
it grows over and smothers coral reefs and native algal communities, killing extensive areas of native habitat.

Three species of invasive alien algae
are devastating Maunalua Bay.
