Botanizing Walker Ridge 6/1/2013 update 6/3/13

Plant List has been updated with many additions and corrections from Glenn Keator and Calflora
(any errors are mine)

Yesterday I went on a field trip with members of the Regional Park Botanic Garden to Walker Ridge. Walker Ridge is north of Highway 20, on the eastern edge of Lake County. It is parallel to west of Bear Valley, a well-known wildflower hotspot. The trip was led by Glen Keator a top field botanist, teacher, field trip leader, and author of botanical field guides and native plant gardening books.

We drove through Bear Valley to get to the beginning of  the road to Walker’s Ridge. As expected most of the wildflowers in Bear Valley were well past. There were some remaining California Poppies and some alien Morning Glory. If you looked at the hills on either side of the valley it was very obvious how the north facing slopes had many more trees than the drier and hotter the hills with southern exposure.

On Walker Ridge we explored mainly by driving the roads and some short walks We found many species in bloom and others that were finished flowering. The only wildflowers that were in large numbers were Clarkias and Delphiniums.

This is definitely a trip for the plant lovers. As we covered a lot of territory today and the focus was on finding plants I only did some quick grab shots.  See the best photos from today below and click Read More to see a very detailed plant list.  Corrections and additions to the plant list by other participants are most welcome.

    • Can you ID him?

      • No, it’s much too small a picture for me to even hazard a guess. If you’re really curious, you can submit an ID Request at Bug Guide. A beetle I photographed in Del Puerto Canyon turned out to be a potentially new species. A biologist went up three times to try to find it and plans to try again next year.

      • That is pretty cool. I don’t think I will submit this one though as it isn’t that important.
