Learn what plants and animals are endangered or threatened in SLO County:
Why are animals considered endangered? Threatened?
In California, animals and plants on the verge of extinction can be classified as threatened, endangered or fully protected.
Under federal Endangered Species Act guidelines, an “endangered” species is “in danger of extinction throughout all or a significant portion of its range.”
A “threatened” species is likely become endangered in the future.
Under the act, animals and plants can get federal protection as endangered or threatened species due to:
- Destruction, modification or curtailment of habitat or range
- Overutilization for commercial, recreational, scientific or educational purposes
- Disease or predation
- Inadequate regulations
- Other natural or manmade factors
According to the California Department of Fish and Wildlife, the term “fully protected” is only used in California to designate species that are rare or facing extinction.
“Most fully protected species have also been listed as threatened or endangered species under the more recent California Endangered Species Act,” the state Fish and Wildife Department said.
How does the California Endangered Species Act work?
The California Department of Fish and Wildlife adds or removes species to its endangered or threatened lists based on regular assessments.
The California Endangered Species Act aims to protect fish, wildlife and plants that are “in danger of extinction” due to factors including overexploitation, disease, predation and threats to their habitats.
“Conservation, protection and enhancement of these species and their habitat is of statewide concern,” state law says.
For a species to be listed under the California Endangered Species Act, the California Fish and Game Commission must complete a formal listing process.
