The sand dune system along Navarre Beach helps protect the mainland and buildings from the force of tropical storms and hurricanes. The dune system absorbs the energy of storm waves

Should we plant Sea Oat Turf?
Many different species of plants naturally occur in the dune system
This diversity offers more opportunities for trapping sand and provides habitat for wildlife
Is it beneficial to plant more than one species when
restoring dunes?
Will a variety of plants trap sand differently than a monoculture?Will survival of a variety of plants differ from survival of a monoculture?

Kiosks are installed at each site to provide information for the public
Citizen involvement and public education are integral to increasing public coastal awareness and
stewardship
How can you help protect dunes?
Footpaths through dunes can cause “blowouts” in the dune system during storms Surging water washes away sand that makes up the dune
Utilize dune walkovers whenever possible!
Coastal Stewardship practices for all…
Avoid picking or damaging dune plants
Keep pets on a leash and out of dunes
Don’t litter
