The Bioblitz Club will be hosting a week-long virtual event using The Pot Fouling Project on iNaturalist.org to support California Invasive Species Action Week, sponsored by the California Department of Fish and Wildlife: https://www.bioblitz.club/post/please-document-invasive-species-under-your-garden-pots

Multiple specimens of an invasive land flatworm were documented in a Campbell, CA nursery this week.

Obama nungara flatworms eat land snails and earthworms - and there were zero snails and near-zero earthworms at this location, which was unusual. I hope these flatworms don't spread to wild areas and go after our native snails. For more on Obama nungara, and their establishment in France:

One day into the new project, already something interesting. This snail was in a plant nursery in Cupertino: https://www.inaturalist.org/observations/101369553
