Nootka alkaligrass

Puccinellia nutkaensis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Nootka alkaligrass faces severe habitat loss from coastal development and infrastructure expansion along its limited Pacific Northwest range. Rising sea levels and increased storm intensity threaten the species' specialized salt marsh and estuarine habitats, while invasive plant species compete for space in these already restricted environments. Human disturbance from recreational activities and shoreline modification further fragments the remaining populations of this endemic grass.

Threat summary
