The California fur-trapping ban refers to Assembly Bill 273 – the Wildlife Protection Act of 2019, signed by Governor Gavin Newsom on September 4, 2019. The statute made California the first U.S. state to outlaw commercial and recreational trapping of fur-bearing mammals, ending a practice that had existed since the early 19th century.
Background.
Commercial trapping of carnivores such as coyote, gray fox and mink had dwindled for decades. 
Wildlife-protection advocates argued that public subsidies for the trade were unjustified and that native species were better valued alive through non-consumptive activities such as wildlife watching.
Key provisions.
The Act:
The law took effect 1 January 2020, allowing CDFW time to phase out licences and notify permit holders.
Implementation and enforcement.
Violations are punishable as misdemeanours carrying fines up to US$2,000 and/or one year in county jail, under amended Section 12002 of the Fish and Game Code. CDFW wardens retain authority to issue citations and seize illegal traps or pelts.
