Puccinellia howellii
Also called Howell's Alkali Grass
Howell's alkaligrass is a rare perennial bunchgrass found only at a single site of saline mineral springs in Shasta County, California. It is a salt-tolerant species that is not commonly grown in gardens, and it is best left in place where it occurs.
Puccinellia howellii is a rare species of grass known by the common name Howell's alkaligrass. It is endemic to Shasta County, California, where it is known from a single population in Whiskeytown National Recreation Area near Whiskeytown. Its entire population is contained in a 1-acre (4,000 m2) complex of three saline mineral springs directly next to Highway 299. The grass was first described to science in 1990 and no other populations were discovered despite extensive searches of the area.
The hillsides surrounding the salt springs where the rare grass grows burned in the 2018 Carr Fire. However the bare, wet gravel slopes of the springs were largely unburned and the Puccinellia population persists.
