Sunday, May 15, 9:45 am, Blue Oak/Spengler Trails in Briones Regional Park

Meet Gregg Weber at the Gloria Terrace staging area so that we can start this half-day hike promptly and take advantage of cooler morning temperatures. Be sure to bring water and some protection from the sun. For a full set of directions and/or to request to carpool from Orinda BART go to, RSVP and post any questions not answered in the trip description.

Sunday, May 15 , 10 am, Hillside Natural Area in El Cerrito (end of Schmidt, near the recycling center)

This plant walk will be one of several field trips starting at 10 am, so it may be easier to find me a few minutes before the walk starts. This field trip is only one of a series of daylong activities at the third Hillside Open Space Festival. For more information on the rest of the festival go to If you go to you can find the vascular plant list compiled in 2014 and more complete driving and mass transit directions. If you want to monitor one of several unusual plants for the chapter find the Unusual Plants Database on the home page of our website, I am eager to find Oakland star tulip, though it’s probably too late to find it in bloom. At last check the giant vetch population (Vicia gigantea) looked pretty stable and will likely still be flowering on the field trip.

Saturday, May 28, 9:45 am, Falls Trail in Mt Diablo State Park

This year’s ascent will provide not just great views of unusual plants in flower, but perhaps also a look at the waterfall revived by this year’s late rains. While I admire the persistence of the May trickle in the face of the prolonged drought it might be a fun change to get sprayed by the waterfall. If you want to carpool from Orinda BART go to be sure to remember that the carpool leaves for the trailhead at 9:15 am. (Driving directions to the trailhead are also on the trip announcement.)
