The Harmful Cyanobacteria Blooms (HCBs) training reviews key information found in the ITRC Guidance Document, Strategies for Preventing and Managing Harmful Cyanobacterial Blooms.
Cyanobacteria are microscopic, photosynthetic organisms that occur naturally in all aquatic systems but most often in freshwater systems. Under certain conditions, cyanobacteria can multiply and become very abundant, discoloring the water throughout a water body or accumulating at the surface. These occurrences are known as blooms. Cyanobacteria may produce potent toxins (cyanotoxins) that pose a threat to human health. They can also harm wildlife and domestic animals, aquatic ecosystems, and local economies by disrupting drinking water systems and source waters, recreational uses, commercial and recreational fishing, and property values. It is likely that continued population growth, land use change, increases in nutrient inputs to our waterways, and the warming climate will favor proliferation of these problematic species. Providing a range of practical approaches to minimize these blooms and their likely societal and wildlife effects is critical to our future vitality, health, and economic prosperity.
The Harmful Cyanobacteria Bloom training provides an overview of cyanobacteria and their management, covering five sections from the ITRC guidance document:
- Introduction to the Cyanobacteria (Section 3)
- Monitoring (Section 4)
- Communication and Response Planning (Section 5)
- Management and Control (Section 6)
- Nutrient Management (Section 7)
After the five-part Strategies for Preventing and Managing Harmful Cyanobacteria Blooms training, you should understand:
- The basic ecology and physiology of cyanobacteria, and the harmful effects they have on health, the environment, and local economies
- Common approaches to monitoring for cyanobacteria and cyanotoxins, and how to build a monitoring program
- The importance of good communication and coordinated response during cyanobacteria blooms, and the elements of a good response plan
- Available options for in-lake management and control of cyanobacteria blooms
- Nutrient management options to reduce the likelihood of cyanobacteria blooms in your water body
We encourage you to use the ITRC HCB Resources (HCB-1) and the recorded training to learn about cyanobacteria, monitoring approaches, management of active blooms, and prevention of blooms in the future. For regulators and other government agency staff, these materials present the current state of the science on cyanobacteria and approaches to manage and reduce the occurrence of blooms. We share examples and resources from across the country that can help you develop approaches of your own. While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of biology, lake management, chemistry, and environmental sciences. As with other emerging concerns, our understanding of harmful cyanobacteria blooms continues to advance. These trainings help you build cyanobacteria response plans now and point you to resources that will keep you up to date in the future.

Presenters:
Gina LaLiberte, Wisconsin Department of Natural Resources (gina.laliberte@wisconsin.gov)
Gina LaLiberte leads response and communication on cyanobacterial issues as the Harmful Algal Bloom Coordinator for the Wisconsin Department of Natural Resources. She has a BS in Biology and a MS in Resource Ecology Management from the University of Michigan. She has studied algae for over 25 years.
Angela Shambaugh, Retired (adshambaugh@myfairpoint.net)
Angela Shambaugh is an aquatic biologist, recently retired from the Lakes and Ponds Program (Vermont Department of Environmental Conservation). Since moving to Vermont in 1986, she has been working in the fields of water quality and phytoplankton ecology for private consultants, the University of Vermont, and the State. In those roles, she participated in the development of a cyanobacteria monitoring protocol for Lake Champlain, one of the largest physically diverse lakes in the northeastern US. The initial monitoring program got underway in 2002 and, in its current form, is used for all water bodies in Vermont. Aspects of it have been adopted by other states in the region. Angela currently serves as co-chair of the North American Lake Management Society's Inland HABs Committee.
