Valley grassland is the plant community native to non-riparian areas of Sutter County below approximately 50 feet, including Abbott, Catlett, Counsman, Cranmore, Cunard, East Nicolaus, Ensley, Hinsdale, Josephine, Karnak, Kirkville, Lira, Marchant, Meridian, Nicolaus, Oswald, Progress, Robbins, Sankey, Subaco, Tarke, Tisdale, Trowbridge, Tudor, Verona, and Wilson. It is defined by the absence of trees and of most shrubs. Winter flooding, extremely dry summers, and soil that tends to be somewhat alkaline make it difficult for trees and shrubs to grow. However, despite the name, native grasses or grasslike plants are usually not the dominant plants either. Before the arrival of Europeans, wildflowers were the dominant plants in the valley grassland areas. Now, ploughed farm fields and invasive weeds—primarily annual grasses from other continents—dominate most of these areas. The ecosystem's health, stability, and beauty can be greatly improved by removing the invasive grasses and planting the native wildflowers listed below.
Some of the lowest-lying areas near valley grassland become so flooded in winter that they can become vernal pools, a seasonal form of freshwater marsh. Freshwater marsh is an even more difficult environment for most types of plants than valley grassland is, and vernal pools are even more difficult than year-round freshwater marsh.
The plants listed below are native to valley grassland in Sutter County.1
Shrubs and Vines
Naked buckwheat (Eriogonum nudum) is named for the fact that it has no leaves except for a few small ones at ground level. Photo by queerbychoice. (See the Buckwheats and Beardtongues pages for more information about some of these species.)

Monocots
Grasses and Grasslike Plants
