The warm, early spring weather soon will encourage vegetative growth in the nutrient-rich waters of Iowa ponds. Pond owners need to know that wherever there is sunlight, water and nutrients, there will be some sort of plant growing. Effective management involves manipulating one or more of these elements to reduce or eliminate aquatic plants.
Iowa State University Natural Resource Ecology and Management (NREM) specialists and faculty talked about physical, chemical and biological conditions of urban streams and the implications of daily actions by individuals with respect to stream health and sustainability during the Science Center of Iowa Cafe Scientifique. The program was recorded and is available online.
