Sea oats, Uniola paniculata, a valuable native MAR 197
sand-binding grass of coastal dun es

K. R. Langdon UvsS Of Florida

Very few species of plants can survive on the ocean side of the first or
foredune along our beaches. Sea oats, Uniola paniculata L. (Fig. 1), is one of
the most important of these, forming a major part of the pioneer vegetation and
helping to bind and stabilize the sand. Some other important plants in this
habitat also helping stabilize the coastal dunes are beach bean or sea bean,
Canavalia maritima (Aubl.) Thouars; beach morning glory, Ipomoea stolonifera
(Cyrillo) Poiret; railroad vine, Ipomoea pes-caprae (L.) R. Brown; sea rocket,
Cakile sp.; and beach elder, Iva imbricata Walter (1,2). Beyond the crest of the
foredune other species of plants also become important. Vegetation along the
coast is the best protection against both wave and wind erosion.

Uniola paniculata is a robust grass around 3 ft (1 m) tall with extensively
creeping underground rhizomes or runners and a deep, wide-spreading root system.
The tall seed heads have long been popular for dried arrangements. It grows in
sometimes extensive colonies along the coasts of the southeastern United States,
the West Indies and eastern Mexico. The distribution in the United States extends

from Virginialto Florida and Texas. The usual habitat for sea oats is in essen-
tially barren sand and sand dunes exposed to wind, blowing sand, and salt spray in
very drought-pirone situations (1,2,3,4). It reproduces and spreads both by seed
Sand by underground runners. Sea oats will tolerate considerable burial by drift-

from both foot and vehicular traffic and other such disturbances.

Section 370.041, Florida Statutes, for beach erosion control, makes it illegal
to harvest or remove sea oats from any public land or from private land without
permission of the owner. This law provides, however, that licensed, certified
nurserymen who grow sea oats from seed or vegetatively are permitted to sell the
plants so grown. Several nurseries in the state can furnish planting material for
use in coastal revegetation.

Several restoration projects utilizing sea oats have been completed or are in
progress. Further use of these and other plants can accomplish much toward pre-
serving our beaches.
