  • If you have a septic tank, have it regularly inspected and maintained;
  • Go native! replace more and more of your lawn and garden with native plant species that require no fertilizer, pesticides or extra watering.  Refer to University of Florida’s Florida Friendly Landscaping program for more information.
  • If your landscaping requires fertilizer, use minimal amounts and adhere to all local fertilizer use ordinances;

  • Be a water detective –  if you see something, say something – report algal blooms, fertilizer and landscaping violations or stormwater problems to Calusa Waterkeeper.

  • Support plans to eliminate septic systems and modernize sewage treatment;
  • Encourage neighbors to replace non-native landscaping with native landscaping and planting;
  • Attend and speak at neighborhood, HOA, town hall, council and agency meetings on land conservation, greenways, water management and conservation


What you see on the land, lands in the sea… via bay… and streams… and tributaries.
