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).
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]
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 ...
Here’s what the law says about smoking on private property and what action you can take if smoke becomes a nuisance: Can you smoke weed in your own backyard in California?
An infestation of non-native golden mussels could cause ecological harm and compromise water infrastructure in the Sacramento-San Joaquin River Delta.
The California Environmental Quality Act (CEQA / ˈ s iː. k w ə /) is a California statute passed in 1970 and signed in to law by then-governor Ronald Reagan, [1] [2] shortly after the United States federal government passed the National Environmental Policy Act (NEPA), to institute a statewide policy of environmental protection.
The spraying will follow legal guidelines, officials said, in effort to make waterways safer.
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.
