The Guayaquil flooded grasslands (NT0905) is an ecoregion near the Pacific coast of the Ecuador.

[1] The Guayaquil flooded grasslands adjoin the Western Ecuador moist forests ecoregion to the west and north, and a section of the Ecuadorian dry forests ecoregion to the east.

To the southeast they merge into the South American Pacific mangroves ecoregion.

[1] Endangered birds include yellow-bellied seedeater (Sporophila nigricollis) and Peruvian tern (Sternula lorata).

Threats come from the steady growth of the human population and large-scale irrigation programs for agriculture.
