Bay Area Macroinvertebrate Bioassessment Information Network (BAMBI)

BAMBI is a network of scientists, watershed managers, regulators and community members interested in using biological communities as indicators of stream health in the San Francisco Bay Area. This is a working webpage for the exchange of current information, focused on benthic macroinvertebrates (BMIs). For general background on bioassessment, see links below

New Zealand Mud Snail - Bay Area alert

The New Zealand mud snail (NZMS, Potamopyrgus antipodarum) is a small hydrobiid snail that is spreading rapidly in fresh and brackish waterbodies in many western states. Just one snail can colonize a stream; within a few years they can reach high densities and displace much of the native macroinvertebrate community, seriously impacting aquatic food webs and habitat.

Several Bay Area locations have reported NZMS, most recently in 2007 from eastern Contra Costa County and in Niles Canyon and lower Alameda Creek.

NZMS can survive on damp wading gear or equipment and hitchhike to new locations. There is no effective way to remove established populations so preventing the spread is important for anglers, researchers and others who regularly enter creeks.

• Know how to recognize NZMS
• Consider potential infestation in planning fieldwork
• Take appropriate precautions in cleaning or decontaminating gear
• Report new sites to CDFG and Montana State - see links below
