Biological Flora of Coastal Dunes and Wetlands: Uniola paniculata L

  title={Biological Flora of Coastal Dunes and Wetlands: Uniola paniculata L},
  author={Robert I. Lonard and Frank W. Judd and Richard Stalter},
Abstract Uniola paniculata C. Linnaeus is a New World, tropical-, subtropical-, and temperate-zone, rhizomatous grass that is often a dominant species on foredunes and on the primary dune complex. Uniola paniculata L. has low freshwater-moisture requirements, tolerates aerosol salt spray, has low nutrient level requirements, tolerates high sand temperatures, and provides extensive sand coverage. Also known as sea oats, this grass inhabits mobile and semistable dune systems and plays a… 


This paper aims to present an overview of Spartina versicolor Fabre populations in the coastal areas of Tuscany (Italy), in relation to its ecology and phytosociology. Geobotanical surveys were

Effect of Sea Oats (Uniola paniculata) Plant Size on Survival and Performance at Beaches with Low Dune Profiles

the gypsum blocks were buried too deeply to effectively measure the applied water. The modest quantities of water that we applied may have penetrated only the first several centimeters of soil,

Evaluating Postharvest Sugarcane Residue Amendment and Broadcast Fertilizer Application as Techniques to Enhance Dune Grass Establishment and Expansion

Coastal dunes are valuable components of barrier shorelines, but establishing the appropriate vegetation to facilitate the growth and maintenance of this important habitat is difficult due to the

Differential response of barrier island dune grasses to species interactions and burial

Barrier islands are at the forefront of storms and sea-level rise. High disturbance regimes and sediment mobility make these systems sensitive and dynamic. Island foredunes are protective structures

Species-Specific Functional Morphology of Four US Atlantic Coast Dune Grasses: Biogeographic Implications for Dune Shape and Coastal Protection

It is hypothesize, given the distributions of the grass species, that foredunes may be taller and wider and have better coastal protection properties in the north where A. breviligulata is dominant, and that changes in grass dominance and foredune morphology could make for more vulnerable coastlines.

Development and Evaluation of Methods to Identify Sea Oats Breeding Lines for Beaches with Shallow Dunes

Sea oats (Uniola paniculata) is an aesthetically pleasing native plant used for beach restoration along the northern Gulf of Mexico coast. Many beaches in this region have shallow, saturated dune

Literature-based latitudinal distribution and possible range shifts of two US east coast dune grass species (Uniola paniculata and Ammophila breviligulata)

An interactive map is produced that summarizes the locations of 98 studies that either stated the range limits and/or included field-based studies/observations of the two grass species, Ammophila breviligulata and Uniola paniculata, and compares them with geolocated records from the Global Biodiversity Information Facility and iNaturalist research grade crowd-sourced observations.

Investigating dune‐building feedback at the plant level: Insights from a multispecies field experiment

Coastal foredunes provide the first line of defense against rising sea levels and storm surge and for this reason there is increasing interest in understanding and modeling foredune formation and

Lateral vegetation growth rates exert control on coastal foredune hummockiness and coalescing time

Abstract. Coastal foredunes form along sandy, low-sloped coastlines and range in shape from continuous dune ridges to hummocky features, which are characterized by alongshore-variable dune crest

Wrack enhancement of post-hurricane vegetation and geomorphological recovery in a coastal dune

It is indicated that subsides of wrack re-distributed from other ecosystem types (e.g. seagrasses, macroalgae, uplands): i) enhances the growth of certain dune-building grasses; and ii) boosts the geomorphological recovery of coastal dunes.



Potential Use of Uniola paniculata Rhizome Fragments for Dune Restoration

Reburial within 3‐11 days after a storm is a viable restoration technique for salvaged and replanted rhizomes uprooted by hurricanes and deposited as wrack to test this unexplored technique.

Expansion Patterns and Soil Physicochemical Characterization of Three Louisiana Populations of Uniola paniculata (Sea Oats)

The only three sizeable populations of Uniola paniculata (sea oats) on the Louisiana coast west of the Mississippi River delta were studied to determine if these populations were in a state of


Investigating sea oats at three natural dune locations found fertilized sea oats in the beach planting and in the island nursery were more vigorous than those growing in the natural, unfertilized dunes.

Construction of Texas coastal foredunes with sea oats (Uniola paniculata) and bitter panicum (Panicum amarum)

Sea oats and bitter panicum proved best of all species tested and both species are capable of growth year round during periods of favorable climatic conditions, although little growth occurs from mid-December to mid-February.

Micropropagation of Uniola paniculata L.

In vitro cultured caryopses of U. paniculata produced callus on MS medium supplemented with 22.5 μM 2,4-D, 4.4 μM BA and 87.6 mM sucrose, and shoot induction occurred after these calli were inoculated onto the same medium without 2, 4-D.

Water relations and growth responses of Uniola paniculata (sea oats) to soil moisture and water-table depth

Although U. paniculata's moisture-conserving traits adapt it well to the dune environment, this species can grow very well at an elevation of only 0.9 m above the water table, which cannot be explained by water-logging stress induced by the low dune elevations and the corresponding shallow water-table depth.


Results indicated that Atlantic coast Florida populations did not require cold treatment prior to germination at 95-65 F, but that populations from Virginia and North Carolina did, and Gulf coast populations exhibited a germination response intermediate between those just mentioned.

Multi-scale genetic analysis of Uniola paniculata (Poaceae): a coastal species with a linear, fragmented distribution.

Geographic and fine-scale population genetic structures of Uniola paniculata, the dominant coastal dune grass in the southeastern USA, were examined. The linear, naturally fragmented distribution of

Spatial and Temporal Distribution of Vesicular-Arbuscular Mycorrhizal Fungi Associated with Uniola Paniculata in Florida Foredunes

The abundance and diversity of vesicular-arbuscular mycorrhizal fungi in pioneer dune populations of Uniola paniculata were determined and the frequency distributions of spore counts were best described by the negative binomial model, suggesting spores were aggregated in the dunes.
