An infestation of non-native golden mussels could cause ecological harm and compromise water infrastructure in the Sacramento-San Joaquin River Delta.
Invasive species in California, the introduced species of fauna−animals and flora−plants that are established and have naturalized within California. Native plants and animals can become threatened endangered species from the spread of invasive species in natural habitats and/or developed areas (e.g. agriculture, transport, settlement).
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
For example, invasive plants can alter the fire regime (cheatgrass, Bromus tectorum), nutrient cycling (smooth cordgrass Spartina alterniflora), and hydrology in native ecosystems. [89] Invasive species that are closely related to rare native species have the potential to hybridize with the native species.
In its fight against invasive aquatic plants in the Sacramento-San Joaquin River Delta, the California State Parks’ Division of Boating and Waterways says it will begin a regiment of herbicide ...
California is the only state with a groundwater law that includes provisions intended to protect groundwater-dependent ecosystems. But the law, adopted in 2014, gives considerable leeway to local ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
California state policy has also recognized the need to protect the chaparral vegetation threatened by the fires. [6] Other threats to the ecoregion include development, overgrazing, conversion to annual grasses, and invasive species. Invasive grasses often appear as the result of fires or human development in chaparral. [7]
