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).
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.
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 ...
Non-native species can provide ecosystem services, functioning as biocontrol agents to limit the effects of invasive agricultural pests. [132] Asian oysters , for example, filter water pollutants better than native oysters in Chesapeake Bay . [ 137 ]
