Abstract: The causes of harmful algal blooms (HABs) are varied and not always well understood, but linkages of some blooms to excess nutrient inputs and hydrologic alterations provide some direction for prevention. Once a bloom has formed, mitigation actions have primarily focused on early warning and detection to eliminate or reduce human and resource exposure, or to provide rehabilitation to distressed wildlife. Efforts to control HABs, defined as a reduction of the magnitude or restriction in the spread after bloom formation, are generally limited to small-scale systems (e.g., ponds and small lakes). The challenge for larger systems (e.g., larger lakes and coastal areas) is balance between the application of an effective control method while limiting unintended side-effects that may disrupt ecosystems and communities. This article provides a brief overview of HAB mitigation and control approaches and outline a path forward to enable informed decisions on balancing their effectiveness with concerns over possible side-effects.
