This month we took on a troublesome patch of cape ivy near the La Bica and Myra entrance. Cape ivy is a particularly noisome adversary because it grows exceptionally quickly and it regrows from the tiniest fragment of stem or root left behind. This patch lies above the main trail into the park and below the most critical grassland areas below the Levi Site — so extirpating this nasty nest is crucial.
Here our valiant group fans upward into the patch, grubbing out the cape ivy as we went:
Fortunately our regular band of volunteers was augmented by a sizable group of students from the Stewart Hall High School. The kids worked hard and successfully. At the end of the day, we had completely removed all visible traces.
Unfortunately, we’ll have to patrol this patch regularly, as there is no way we could avoid leaving a fair bit of root behind — which will spring quickly back up. Still, substantial progress was made in protecting the vital areas further up the hill.

I look forward to visiting Mt. Davidson soon. This place features significant habitat for migrating birds and rare native plants.

On an incomparably gorgeous day such as today, there is nothing finer than planting native plants in a public space — which is exactly what the Edgehill Mt Volunteers did today. We managed to install 180 plants — California fescue, California brome, California melic grass, elderberry, and mimulus — in our regular two-hour workparty.
Unfortunately, the flip side of this gorgeous weather is that the winter rains are failing us, so we also had to spend a fair bit of time watering in these new recruits.
However, even with only the occasional watering that we can manage, our success rate has been excellent. The areas we’ve been working on for the past number of years are looking spectacular! Nearly all the planted stuff is thriving, and we continue to discover new remnant populations that emerge once the weeds are reliably out of the way.
One very welcome result from the clear skies is that the ehrharta grass plague is in remission. Ehrharta does not do well at all when dry, so if climate change accomplishes nothing else, it may help eradicate ehrharta from the Bay Area.
