Restoration Update
Photo by R. Byrnes
Last week we focused on removing invasive Black mustard (Brassica nigra) at Lusardi Creek. We got an early start on it this year. Mustard is widespread at Lusardi and we’ve been dealing with it for a couple of years, since we first became alarmed over how thickly it was growing. Though mustard seems to be advancing into new areas, other areas are finally showing a decrease in density. We also continue to hope that over the long term the spread of taller perennial natives will shade out the mustard, which is an annual and is short when it starts its yearly cycle of growth.
The photo above is of one young native, California sagebrush (Artemisia californica). The heavy rain we’ve had this winter seems to be favoring such recruits.
This week I have Tuesday, Thursday, Friday, and Saturday to work with Committee members. Email me if you can help.
