Today on Marine Science Minute with Florida Sea Grant: Sand dunes 

Did you know that sand dunes are nature’s line of defense? Sand dunes are natural coastal mounds formed by the accumulation of wind-blown sand, support unique ecosystems and wildlife, and protect against storm surge.  

Unfortunately, many of Florida’s dunes are degraded by improper coastal construction or washed away by hurricanes, leading to the need for restoration. Florida Sea Grant provides resources for restoring dunes, but everyone can do their part.  

Foot traffic weakens dunes through trampling and erosion. You can protect dunes by using only designated beach access points and walkways, leaving those beautiful sea oats untouched, and being mindful of dune restoration areas. Remember, dune vegetation grows by the inch, but dies by the foot!
