This publication addresses aquatic plant management in Indiana lakes. Section 1 discusses the types of aquatic plants in a lake environment, their benefits to the lake, where different species grow in the lake, what factors affect their growth, and concerns about threats to their survival. Section 2 looks at the problem of excessive aquatic plant growth and the keys to maintaining a healthy plant community. Then, presented in table form, are four management options - physical, chemical, biological, and education - for controlling excessive plant growth, as well as information about regulations and required permits. Section 3 describes the effects of poor land management on a lake's ecosystem, the components of a good aquatic plant management plan and an introduction to shoreline landscaping. Also included is a list of sources of information, related publications and a glossary of terms.
