In communities with lakes and ponds, managers need to be vigilant to prevent cyanobacteria - also known as blue green algae. Algae is a natural component of any lake or pond system. But in more and more communities that include water features, harmful algal blooms (HABs) are increasingly common. Whether naturally occurring or human induced, large concentrations of algae blooms can threaten a pond system’s chemical balance and create conditions that could be toxic to humans or wildlife. Environmental changes or pond nutrient (nitrogen and phosphorus) imbalances in the water can encourage and intensify toxic algae.
Cyanobacteria are the primary culprits of HABs. For this reason, many states are adopting the U.S. Environmental Protection Agency’s (EPA) cyanobacteria guidelines to
