HAB's Research, Resources, and Tools Members of tribal communities, water utilities, city and county government agencies, local and regional watershed groups, state environmental and health agencies, federal government, local and national environmental non-profits, universities, and attendees from academia and non-profit research organizations from Portugal, Canada, and Denmark joined the three-part webinar series on the impacts of marine and freshwater HABs in tribal communities held on March 10, 16 and 18. More than 300 people attended the webinar on each of the respective three webinar days. This webinar series is the first of its kind and the largest national effort to engage tribes in managing the unique challenges that HABs pose to their communities. Recordings and presentations will be posted to the EPA CyanoHABs website soon. EPA, NOAA and the Sitka Tribe of Alaska's Managing Harmful Algal Blooms in Tribal Waters Webinar Series ------- NEWS ON HABs ITRC's New Strategies for Preventing and Managing Harmful Cyanobacterial Blooms (HCBs) Guidance On March 19, the Interstate Technology & Regulatory Council (ITRC) Harmful Cyanobacterial Blooms Team (HCB) Team published a technical guidance document with useful tools and resources on prevention, monitoring, mitigation strategies, communication and response to planktonic HCBs. The guidance, intended to assist waterbody managers and other interested parties to respond and manage harmful cyanobacterial blooms, provides several tools to help them select appropriate methods for monitoring, managing of nutrients and response planning. Along with the guidance, the HCB Team also developed a series of downloadable sheets that provide descriptions of management strategies evaluated for effectiveness, advantages, limitations, relative cost, and regulatory and policy considerations. In the next few months, the ITRC's HCB Team will be hosting live internet-based training sessions to accompany this new guidance. Members of the ITRC HCB Team included representatives from States and Local Health and Environmental Agencies, academia and federal government. CDC Releases Spanish Language Cyanobacteria Health Promotion Web Pages The CDC recently translated to Spanish health promotion resources on cyanobacteria. See the resources here: 1) Information for animal owners: Alerta para la seguridad de los animates 2) Information for healthcare providers: Referenda para los medicos sobre las proliferaciones cianobacterianas 3) Information for veterinarians: Referenda para los veterinarios sobre las proliferaciones cianobacterianas 4) Animal safety poster: Posters I Harmful Algal Blooms I CDC 5) Physician, veterinarian, and pet or livestock owner reference cards: Reference Cards Virginia Department of Health (VDH) Guidance for the Recreational advisory management of cyanobacteria Available for Public Comments The Virginia Department of Health (VDH) has proposed updated guidance for the recreational advisory management of cyanobacteria. The guidance is available for formal public comment March 15 through April 14.
