Ranger Program


Inquire Now

Calusa Waterkeeper Rangers are community volunteers interested in helping monitor and advocate for water quality issues in Southwest Florida. We hold basic training courses annually to educate new Rangers, and are currently developing more advanced courses for existing Ranger graduates. Our Ranger team is a terrific variety of backgrounds and expertise and many are very active in local advocacy initiatives.
