Dune vegetation is fragile and is easily destroyed by vehicular traffic.
Vegetation breaks the force of the wind and helps to keep the sand from blowing away.
Vegetation provide food, shelter and nest sites for many animals. Vegetated areas are generally closed to vehicular traffic, but there are some exceptions. Closed areas are signed or fenced. Don't blaze trails through vegetation. With ongoing support from park visitors, this nesting program has been a huge success.
