Gulf Islands National Park Service U.S. Department of the Interior Gulf Islands National Seashore Florida District Barrier Island Wildflowers Where they live Gulf Islands National Seashore’s barrier islands are home to a large variety of plants. The most noticeable are the wildflowers. Wildflowers are found in different plant and animal communities. Each community has a particular combination of environmental factors (soil type, light intensity, wind exposure and moisture) that determines where certain plants live. Plants help hold sand in place and provide food and shelter for animals. These plant and animal communities are critical to the survival of the barrier islands. For this guide, the following communities are used: Dune Sand dunes up to 30 feet in height that are parallel to the Gulf of Mexico and often continuous in appearance. Dunes are dry and sandy. Includes areas adjacent to dunes. Primary dunes (P) are closest the Gulf, secondary dunes (S) are behind primary dunes. Swale - Low, wetland areas with moist soil; may be flooded with rain water. Forest - Taller pines and oaks, shrubs and other plants grow in dry, sandy soil. Marsh - Contains standing freshwater (f), saltwater (s) or a mixture of both. Disturbed - Areas altered by people, usually near roads and/or structures.
