In addition to dealing with the usual invasives Artichoke thistle (Cynara cardunculus) and Carnation spurge (Euphorbia terracina), we surveyed a part of Lusardi Creek we hadn't been able to access for several months because of mud and high water. We found more Carnation spurge as well as familiar invasive Algerian sea lavender (Limonium ramossissimum).
We also saw a clump of a nonnative species we've encountered only once before, Purple salsify (Tragopogon porrifolius), an edible herb from Europe. It is not invasive but it is difficult to eradicate. We will try in coming weeks.
This week I have Wednesday, Friday, and Saturday to work with Committee members. Email me if you can help.
