Hillside walk, 15 December 2014

Again a week with rain, this time 73 mm over two days that came as great downpours. The ground in many places is a multitude of tiny seedlings. I cannot way what they are although it's easy simply to say “everything”. Grass is growing profusely in places where grass grows.

I took a midweek walk to the top of the north hillside and found a more-or-less uniform spreading of eroded sand (decomposed granite) across the slopes. Major use trails, including some of my own, show significant erosion. Canyon 8 completely filled the debris basin and the drain inlet behind the houses, and a small amount of sandy effluent spread down over the street.

The liverworts (Asterella californica) in Canyons 2B, 2C, 5, and 6 are now as green as ever. So far no sign of reproduction.

At this point no flowers from recent rains are evident. Some wild cucumber (Marah macrocarpa) is in bud, but it's not clear that it's a result of the rain. On the other hand, the rain has damaged some flowers, such as telegraph week (Heterotheca grandiflora), which is looking battered. The storm was a strong one.

Some plants are in flower, but almost certainly because of the season, not because of the rain. This includes the chaparral currant (Ribes malvaceum), which is in high bloom, and for the first time this year, lemonade berry (Rhus integrifolia).

On the steep upper north hillside I found a Stephanomeria in bloom. I first saw it two weeks ago when it's few flowers were old, as well as wilted by rain, making identification uncertain. With fresh flowers, the identification today was easy.
