California will spend big bucks on beavers to try to boost their numbers and reap some of the benefits—including slowing wildfire—these ecosystem engineers can provide.

After years of advocacy by beaver “believers,” the state has allocated funding for a beaver restoration program. The $1.67 million in license plate funds for fiscal year 2022-23 and $1.44 million the following year represents a new way of thinking about beaver management in California, says Kate Lundquist, of the Occidental Arts & Ecology Center. “Until recently, the Fish and Game Code has focused on recreational and commercial beaver trapping and permitting the depredation of nuisance beaver,” she explains. “I...

Two recent exercises in modeling the hydrological effects of forest thinning and wildfire are yielding intriguing insights.

Hydrogeologist Fadji Maina and colleague Erica Siirila-Woodburn of the Lawrence Berkeley National Laboratory ran simulations of wildfire effects in the Cosumnes River watershed (see map). “We chose the Cosumnes because it’s one of the largest rivers that has no dam in California,” explains Maina. The most significant findings concerned the way wildfire affects groundwater recharge and storage. “It depends on where the wildfire occurs,” says Maina. The underlying rocks—foothill volcanics or High Sierra granites—make a difference. Consistent with earlier studies, the model also...
