Fall on The Mountain brings us cool foggy days, sprinkles of rain and Nature’s berry bonanza to the delight of both resident and migrating birds. Doug keeps his eared perked up for arriving wintering warblers, and eyes up for migrating raptors passing through on their way to breeding grounds.
In his Mountain Journal for Summer 2018, Doug addresses the importance of our fog - and reminds us that this source of moisture is a critical factor for our coastal flora. As we endure our typical summer of fog, it’s a good time to remember that many plants on San Bruno Mountain depend on this summer regime for survival.
A visit to Owl Canyon guarantees surprises as you find in David and Doug's most recent rare plant alert. So keep your eyes out, there are always new species to be found, even on our old friend, San Bruno Mountain. Remember to share your finds with David and Doug who search the Mountain every weekend for new finds.
All of the rain this season meant showy displays of local flora to be enjoyed this Spring. Doug enjoyed them all in his wanderings - owl's clover, goldfields, johnnie tuck and clarkia. Birds also enjoyed the abundance - and Spring arrivals like Swainson's Thrush and Wilson's Warbler could be heard singing. And there is an exciting butterfly story - the reintroduction of the extirpated Bay Checkerspot butterfly to the Mountain by Dr. Stu Weiss of Creekside Science.
We were treated to a Winter with water - and lots of it! - a novel concept for the last several years. Storm after storm, dropping inches of rain, created waterfalls in Owl Canyon and seasonal wetlands not seen in ages. Doug spent this last Winter enjoying all the Mountain had to offer - rain or shine - often with his fellow botanist David Nelson. Together they've made several interesting discoveries on the mountain.
