updating preliminary results of Rancho Sta Fe CBC 12-27-20

Thanks to all who helped make this CBC happen & so successful!

Most groups have reported in but I haven’t received results from several yet.  Despite that, it is looking like this year may have the second highest number of species recorded on this CBC (199 sp + 3 subsp).  (Phil aptly observed that the trickling in of results yesterday were reminiscent of election results…)
