Visitors can walk the Quail Ridge Reserve from 1 to 5 p.m. Saturday. The reserve is on a peninsula at the southwest end of Lake Berryessa.
The walk, along hillsides of California native grasses, wildflowers and trees, is of easy to moderate difficulty and will be led by Frank Maurer, a zoologist and ecologist and executive director of the Quail Ridge Wilderness Conservancy.
Because of recent rains, the abundant native bunchgrasses along the trial will be green and full. Toward dusk, visitors will use an ultrasonic device to hear bats as they begin their evening feeding and forest owls vocalizing.
Visitors should dress in layers for cool evening temperatures and bring binoculars, a camera, drinking water or snacks.
The group will gather at 1 p.m. at Markley Cove Resort to begin the walk, and will return at about 6 p.m. All participants must leave the reserve at the same time. The walk will be canceled only in the event of substantial rainfall during the day.
Donations for the conservancy’s work to protect Quail Ridge are welcome. RSVP by Friday to 530-219-4477.
