Recommendations• Need more forest and native grasslands in rivers landscapes

– especially in floodplains*• Need new businesses that will pay landowners to grow river

friendly crops• Rivers need ongoing Sweeping – people keep treating rivers

like dump**• Probably need for new comprehensive programs to eliminate

endocrine disrupting compounds getting into environment

* Invasive species becoming real problem** Especially in water supply rivers – tires leach endocrine

mimicking compounds
