California took a significant step toward potentially reintroducing grizzly bears, predators that have been absent from the state for more than a century. A bill mandating a feasibility study on bringing back the species passed the state assembly’s water, parks and wildlife committee with an 8-2 vote. The measure had already received approval from the state senate on May 27.

The legislation, sponsored by Democratic state senator Laura Richardson of San Pedro and supported by two Native American tribes, aims to explore whether grizzly bears can be safely reintroduced. It requires that any reintroduction effort ensure the safety of local residents, livestock, and pets before proceeding.

Grizzly bears, which can weigh up to a quarter of a tonne, once roamed California but were driven to local extinction more than 100 years ago. Their potential return comes amid ongoing challenges in managing other protected predators in the state, including wolves, mountain lions, and black bears. These animals are protected by law from hunting and harassment, complicating efforts to balance wildlife conservation with concerns from human communities.

The proposal has sparked opposition from residents in regions where encounters with these predators have already posed issues. Critics argue that the reintroduction of another large predator could exacerbate existing problems and increase risks to people and domestic animals. Supporters emphasize the ecological benefits of restoring an apex species to California’s ecosystems and highlight the careful study mandated by the bill to address safety concerns.

As the measure moves forward, state officials will conduct comprehensive evaluations of ecological, social, and safety factors to determine whether grizzly bears can be reestablished in California without undue risk to its human and animal populations.
