"Herbaceous and grass-dominated ecosystems are critical components of Earth's land surface... Examples of these “grassy” ecosystems are grasslands, shrublands, tundra, open tree savannas, and woodlands" (Wilcox et al. 2023).

"Native grasslands are “grasslands” where >50% of the vegetative ground cover is composed of indigenous species of grasses and forbs (species native to the area before European settlement), >50% of the number of species are native, and where the minimum standing vegetation ground cover, alive or dead, exceeds 10%."

California’s relatively intact grasslands are reservoirs of biodiversity. Grassland birds, mammals, reptiles, insects, pollinators and other animals depend on the resources these plants and spaces provide.

• Native grasslands support about 40% of California's total native plant species (Wigand 2007:55).
• Over 300 species of native grasses are found in California. Grasses are an integral part of diverse habitats, ranging from cool, wet forests to hot, dry deserts.
  
• An astounding 90% of California's rare plant species reside in grasslands (Skinner & Pavlik, 1994; Eviner, 2016).  
  
• California's grasslands are home to 30% of species listed as threatened and endangered (CDFW 2022).
•  Currently 73 grassland-associated species are listed by the state & federal Endangered Species Acts: 14 vertebrates and 59 plants, and 14 invertebrates, including 6 butterfly species. This count does not include unlisted native pollinators and other plants and animals experiencing sharp declines.

Habitat: Grasslands are essential open habitats that provide necessary food and shelter for many birds, insects, and animals.

•  "Old-growth" grasslands are ancient ecosystems characterized by high herbaceous species richness, high endemism, and unique species compositions.

• The decline in native grasses and grasslands in the last two centuries has been caused by intensive cultivation, poorly managed grazing, urbanization, fire suppression, and the introduction of invasive, nonnative species.

• Agriculture, invasion by exotic species, development, and other human-related activities have reduced California native grasslands by 99%.
