Ponds provide important resources, as well as add beauty to our landscapes. But when overgrown with nuisance plants and algae, they can become impractical eyesores. It takes knowledge and active management to control nuisance growth.

In this asynchronous, self-paced course, Extension educators from the water team will teach you about the causes and prevention of excess plant and algae growth. Through videos and short readings, you will become more knowledgeable about pond measurements, plant identification, and control methods. Using an integrated pest management approach, you will learn how to design and implement effective management and control solutions. Check your learning questions after each subsection will help you apply what you learn.

By successfully completing this course, including passing a final quiz, you can earn 3 Pennsylvania Department of Agriculture (PDA) Category 9 credits, as well as a course certificate of completion.

(Note: it may take 2 to 4 week for recertification credits to be reported to and verified by PDA.)
