An infestation of non-native golden mussels could cause ecological harm and compromise water infrastructure in the Sacramento-San Joaquin River Delta.
Ecologists are concerned with the health and diversity of ecosystems. Invasive species can out-compete native species, thereby harming a location's natural heritage and causing monocultures, which are more vulnerable to threats and changes in the environment than are heterogeneous plant and animal communities.
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 California Endangered Species Act put into effect the Department's authority to determine the designation under which wildlife was labeled as "rare" or "endangered" and provided restrictions on the importing and moving of those species except by permit. At the time, this Act did not include plants or invertebrates. [citation needed]
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 ...
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 ...
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 ...
