Volunteers wanted!!! On July 4th come and assist with an innovative research project to treat yellow flag iris infestations using benthic barriers (rubber membranes) and help reduce the threat of this priority invasive species from entering Kootenay Lake. The main project goal is to determine how effective the benthic barriers are to control and/or eradicate current yellow flag iris infestations. We need you help to install the benthic barriers, following the protocol developed by Thompson Rivers University, and for clipping flower heads and seed pods.
