20 October 2015 - Help provide samples of Hydrilla vegetation from Corps reservoirs this fall and winter
Dr. Susan Wilde, UGA is requesting assistance from Corps for this fall and winter. The purpose of the sampling is to detect additional occurrences of a new cyanobacteria that is a causal factor in AVM. She has confirmed the bacteria on Hydrilla at multiple reservoirs and it appears to be moving north.

Current known locations of the cyanobacteria on Hydrilla
Plant collection protocol

If you are willing to provide her with samples should contact her first to let her know samples are coming and to obtain a copy of the APHIS permit required to ship this invasive species.
