Climate Change Could Increase Exotic Grasses In California

University of California Berkeley researchers recently concluded that warmer temperatures could lead to an increase in exotic grasses in California. Possible consequences could include:

  • exotic grasses typically are taller , have longer and wider leaves and larger seeds over natives which gives them a competitive edge over native species
  • exotic grasses compete with native grasses for water
  • increased wildfire risk as exotic grasses dry out faster than natives
  • exotic grasses are a source of pathogens that attack food crops
