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).
In general, invasive species can potentially do great damage to local environments and native species. Ecosystems across the United States, such as the San Francisco Bay, Chesapeake Bay, the Great Lakes, Hawaii, and Florida inland waters, are now host to a wide number of non-indigenous species, 15 percent of which cause serious harm.

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 ...
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 ...
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.
The spraying will follow legal guidelines, officials said, in effort to make waterways safer.
As a result, species and habitat loss have become a major issue. Over 90% of California's coastal wetlands have been lost, coastal waters have become contaminated with a variety of urban and agricultural toxins, and a large number of targeted species have declined in the last 10–20 years. [3]
