Sept. 12 Cleanup Report

The September cleanup was a quiet affair, but there was not much to do either. As Candy said, it was about as clean as the park has been. There were very few castor bean plants around. I am seeing an upsurge in the Russian thistle (Salsola tragus).

Russian thistle (Salsola tragus), probably already gone to seed.

According to UC Integrated Pest Management the best way to handle this plant is to mow or cut, not dig, out young plants before they set seed. Russian thistle needs loosened soil to germinate, so it is best not to disturb the soil. We will have another group of boy scouts coming in October and they will remove as much Russian thistle as they can. We will then learn to identify it right as it germinates and go after it like we did the castor bean. Good news about the weeds is that as the park matures and native plants get going, especially in the central area, the weeds become less of a problem.

Lots of acorns on the oaks. We should make like the squirrels and collect them and bury them in places we want to have oak trees.
