Algal Bloom Action Team

Spring and summer have arrived and with it comes warmer temperatures, longer days, potentially more rainfall, and fertilizers added to crops and lawns.  These factors can be problematic for surface waters, particularly lakes, and may contribute to a previously clear looking blue lake to one that looks green, brown, or in some case, red. The likely cause of this change in color is algae in the lake, responding to excess nutrients and optimal environmental conditions for their growth.  While most algae are not a cause for concern and are an important component of any lake ecosystem, there are some algae-like organisms that can produce toxins.  They’re really bacteria, known as cyanobacteria, but they look like algae.

The cyanobacteria are not new and are among the oldest living group of organisms on earth.  While not all cyanobacteria produce toxins, the ones that do are lumped into a group called Harmful Algal Blooms or HABs. They have been in the public eye lately, and people want to know more about them.

The Algal Bloom Action Team has responded to the call for more information through bulletins, webinars, Frequently Asked Questions (FAQs) and an annual research symposium. Check out these resources, and more, below! Our Third Annual Harmful Algal Bloom Symposium is coming up January 5-6, 2023. More information here!

Algal Bloom Action Team Webinar Series

The Algal Bloom Action Team is hosting a webinar series as an extension to our annual virtual research symposium.. Webinar’s will be held bimonthly. Presentations will last approximately 40 minutes with time for discussion at the conclusion of the session. This event is hosted by the North Central Region Water Network and recordings can be found by visiting our YouTube channel.

Upcoming Webinar:
Harmful Algal Blooms Webinar Series – Forecasting HABs and Developmental Impacts of Neurotoxin Exposure on Aquatic Populations
Wednesday, December 7th at 11AM CT

The Algal Bloom Action Team is hosting its final webinar of the 2022 series on December 7, 2022. This installment will feature Dr. Richard Stumpf from the National Centers for Coastal Ocean Science at NOAA and Dr. Jessica Ward from Ball State University. This session will examine forecasting and monitoring cyanobacterial blooms and overviewing a recent assessment of the effects of developmental exposure to neurotoxins on minnow interactions.

Algal Bloom Action Team Educational Resources

  • Frequently Asked Harmful Algal Bloom Questions
    in the fall of 2020 the team created a database of Frequently Asked Questions or FAQs surrounding HABS. These questions cover identifying, monitoring and treating HABS, human health and HABS, and animal health and HABS. This resource can be used directly by communities and landowners, incorporated into state-based outreach materials, or used as a reference in educational programming. Access the FAQ here
  • Harmful Algal Blooms – What You Should know
    This factsheet covers general harmful algal bloom information and is intended for educators to use when conducting HAB outreach and education. It can also be shared with fellow educators and community organizers as it shares key HAB messages for engaged citizens, professionals and the general public. Access the factsheet here.
  • Harmful Algal Blooms – Prevention and Treatment for Landowners
    This factsheet outlines what landowners can do to prevent harmful algal bloom on their property and how to approach treating blooms when they do occur. Access the factsheet here.
  • Partnering to Mitigate HABs in the North Central Region of the US: A White Paper
    One of the first efforts the Algal Bloom Action Team undertook was developing a white paper, which was related in August 2019, outlining the next steps to address Extension needs related to harmful algal blooms. The white paper documents existing responses to HABs related issues, outreach programming needs in the North Central Region, and outlines recommendations for strengthening research and outreach efforts.  Access the white paper here.

The team is working on creating additional factsheets addressing human health, animal health and more.

Other Harmful Algal Bloom Resources to Note

In addition to the resources from our team, we want to make you aware of other harmful algal bloom resources which can be helpful to when conducting HAB outreach and education.

Also, The Cooperative Institute for Great Lakes Research (CIGLR) is seeking a postdoctoral fellowship to focus on Harmful Algal Bloom Dynamics and Toxins. More information here.
