The largest remaining wetland prairie in the San Joaquin Valley will open to the public on Saturday, March 29, an event that only comes around once or twice a year. The James K. Herbert Wetland Prairie Preserve, which houses and protects rare and unique species in Tulare County, will be open from 9 a.m. to 1 p.m. Attendees can explore the preserve and catch a self-guided tour with staff. The event is made possible by the  Alta Peak California Native Plant Society, Sequoia Riverlands Trust and the Tulare Kings Audubon Society.
