Hillside walk, 18 May 2015
Last Friday evening an unseasonal winter-type storm resulted in 23 mm of rain, mostly within the few hours of a thunderstorm with plenty of lightning and thunder. At one point our weather station was reporting rain falling at a rate exceeding 30 mm per hour. Today, less than three days later, the aftermath of the storm is evident primarily in minor erosion, especially in hillside tracks. The ground looks as dry as ever.
The expected botanical impact of the storm is that the liverwort (Asterella californica) is again green, although not as prolific as it would be if this were in mid winter. The two species of fern are also green again.
The native flowers continue on their seasonal path. Most notably, the sacapellote (Acourtia microcephala) has good blooms on the north hillside, which should spread to other locations before long. The laurel sumac (Malosma laurina) is coming into bloom in many places. At the bottom of the north hillside, clustered tarplant (Deinandra fasciculata) is at its peak.
