Uses

SE US Coastal & Shoreline Restoration: Smooth cordgrass is a unique plant species that when established properly and under applicable conditions has proven to provide significant erosion protection to shorelines, canal banks, and other areas of coastal wetland loss. Smooth cordgrass is used primarily for erosion control along shorelines, canal banks, levees, and other areas of soil-water interface. In addition, smooth cordgrass is an effective soil stabilizer used on interior tidal mudflats, dredge-fill sites, and other areas of loose and unconsolidated soils associated with marsh restoration. When established in conjunction with shorelines, smooth cordgrass provides an effective buffer that dissipates energy, reduces shoreline scouring, and traps suspended sediments and other solids. Dense stands of smooth cordgrass are efficient users of available nutrients, producing significant amounts of organic matter. The cumulative effects of organic matter production, sediment trapping, and erosion control not only provide shoreline protection but also accelerate sediment accumulation and near-shore building. Consequently, smooth cordgrass is a sustainable and renewable restoration resource, and when properly established and in the appropriate habitat, will persist and potentially remain effective indefinitely.

Status

Grass Images Texas A&M University Smooth cordgrass is a native species critical to Barrier Island and wetland restoration along the southeastern coastal states, while it is introduced into areas on the Pacific coast, where has become an aggressive invasive species. Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status, such as, state noxious status, and wetland indicator values.

Weediness

Smooth cordgrass has been introduced along the U.S. West Coast and is very invasive. Consult the links found at the bottom of the PLANTS Plant Profile for additional information regarding this species along the Pacific coast, particularly in California and Washington.

Description

General: Smooth cordgrass is a herbaceous, native, warm season grass that forms dense vegetative colonies along shorelines and inter-tidal flats in coastal wetlands. Smooth cordgrass is a robust, rapidly spreading plant, tolerant to fluctuating water depths and salinity. Smooth cordgrass spreads primarily by vegetative propagation, producing new stems from an extensive system of underground rhizomes. Plant height will vary according to site conditions, but generally will range from 24” to 72.” Colonies tend to grow parallel to and continuous along shorelines; the width and thickness of a vegetative colony is controlled by a number of site-specific conditions such as elevation, shoreline-slope, and frequency, depth, and duration of flooding. Distribution: Generally, this species occurs in the coastal states along the U.S. It is not native on the West Coast. For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.

Establishment

Adaptation: Smooth cordgrass is an inter-tidal brackish plant species. It is described as a facultative halophyte; that is, it will tolerate salt, but salt is not a requirement for its growth. Smooth cordgrass can be established in freshwater, however, numerous field trials have demonstrated that smooth cordgrass is difficult to establish and will not persist under freshwater field conditions. The ideal salinity range for establishing and growing smooth cordgrass is 8 to 33 parts per thousand or brackish to saline habitats. Smooth cordgrass can be established and will persists in areas of elevated salinity (such as salt-flats and tidal lagoons), however plants in high saline habitats tend to be stubby and less robust, generally resulting in thinner and more open vegetative stands. Of primary importance in site selection is that the site be inter-tidal. Smooth cordgrass is critically sensitive to reduced soil sulfides, a condition common to anaerobic and brackish marsh soils. Smooth cordgrass should not be planted outside of the tidal zone. Smooth cordgrass will tolerate fluctuating water levels. Optimum water depths for establishing plants are 1” to 18”. Plantings in deeper water have been successful, however plants are slow to anchor and vegetative cover is sparse. Consequently, plants are more prone to washout, and minimal shoreline protection is achieved. Smooth cordgrass is adapted to a wide range of soils from coarse sands to clays and mucks. Plant establishment and productivity appear to be superior on heavier mineral soils such as mucky clays, silty clays, silty clay loams, and fine sands. Soils with very high levels of organic matter pose structural problems and have proven to be problematic in establishing stands of smooth cordgrass. Considerations: There are a number of other site-specific elements that should be considered when working with smooth cordgrass. These conditions represent extremes and should be thoroughly investigated prior to committing to a significant project if any of these conditions occur. • Soil load-bearing properties -- It is not uncommon for soils (especially in dredge deposit sites) to be fluid to the point that they physically will not support the weight of plants. This is an indicator of soils with a very high water-to-mineral ratio. • High organic soils – Smooth cordgrass will not survive in soils with extremely high levels of organic matter. These soils are described as having very low bulk density and are problematic. When soil texture approaches the consistency of peat moss, there is potential for low plant survival. • Poor water circulation – Smooth cordgrass is critically sensitive to sulfide accumulations and has a relatively low tolerance to sulfide toxicity. • Shoreline configuration – Abrupt and steep cut- banks are indications of high wave energy and/or highly erodible soils. Special precautions may be required to keep transplants from dislodging prior to becoming established. • Herbivore grazing – Smooth cordgrass is a favorite of numerous grazing animals. In areas of heavy nutria population, caging plants may be required to protect newly planted material. • Smothering – Precautions should be taken when planting in areas of heavy floating debris. Both mechanical damage to the plants from surf-trash and smothering from water hyacinths are common. If any of these conditions are present, consult with a wetland specialist for additional information and/or possible alternatives. Planting: Smooth cordgrass is a poor seed producer. Although plants appear to produce a significant number of seeds, most seeds are empty, damaged, or sterile. Consequently, seed fertility is low. For planting purposes, two forms of vegetative plant materials are recommended: containerized and bare-root plugs. Both plant forms have shown to be equally successful in establishing plant stands when planted properly and on applicable sites. There are no commercially available sources of seed, and seeding is not currently a recommended practice. Smooth cordgrass can be produced in a number of container sizes, however trade-gallons are the most widely used and most popular size. Trade-gallon containers have a higher per unit cost compared to smaller containers or bare-root plugs, but provide the most reliable means of establishment. Trade-gallon plants have proven to be a highly successful transplant, especially along shorelines and other areas of high wave energy. A trade-gallon will have 5 to 12 aerial stems that are 18” to 24” in height. Smooth cordgrass produces new tillers (stems) and spreads almost entirely from rhizomes. Consequently, a well-developed root mass is critical to the survival and productivity of transplants. Bare-root plugs are the most economical of the commercially available plant sizes. Per unit production costs are low and transportation costs are very low compared to container plants. Bare-root plugs are generally limited to planting sites that have little or no energy exposure. Typical sites would include mudflats, sediment disposal areas, terraces, or other interior and protected sites. Bare-root plugs because of their limited surface area will not persist in high-energy environments. They tend to dislodge prior to establishing. Bare-root plugs have significantly less rootmass than container plants, will suffer a higher level of transplant shock, and are slower to spread than container plants. However, if handled properly and used on an applicable site, bare-root plugs can be highly successful transplants. Bare-root plugs typically consist of 3 stems 12” to 18” in height, and stems should remain attached at the root. Plugs should have a rootmass of at least 2” in diameter at the root crown and 6” of root length. A complete description (specification) for both trade-gallon container plants and bare-root plugs is available from the Natural Resources

Conservation

Service in Louisiana, Planting Date: As a general rule, smooth cordgrass can be planted between April 1 to September 30, Some additional considerations include the following: • Smooth cordgrass can be planted anytime past the last frost date if there is a need to plant earlier and available transplants are actively growing, In some areas this may be earlier than April 1, • In interior marshes with poor water circulation, avoid planting between mid-July and the end of August, Elevated water temperatures are generally detrimental to new transplants; therefore July and August plantings should be limited to lakes, bayous, and other areas of frequent tidal exchange, • Late fall plantings in October and November have been successfully made in the past, but should be limited to sites that are well protected and have minimal winter storm effect, Planting Location: It is critically important to remember that smooth cordgrass is strictly an inter-tidal plant species and must be planted within the inter-tidal zone, Smooth cordgrass can be used for erosion control along shorelines, canal banks, levees, and other areas of soil-water interface, In addition, smooth cordgrass is an effective soil stabilizer used on interior tidal mudflats, dredge-fill sites, and other areas of loose and unconsolidated soils associated with marsh restoration, Shoreline Plantings: Shoreline plantings are typically planted as a single row parallel to the shoreline, Transplants should be planted at the mid-point between the high and low tide elevations, Plant spacing within the row will vary according to the size of the transplant materials being used and the rate at which full coverage is desired, Trade-gallons generally are planted on 5’ to 8’ centers and plugs generally on 2’ to 3’ centers, Under applicable site conditions, smooth cordgrass will spread laterally filling spaces between plants and will grow up to its highest elevation and down to its lowest elevation, It is not uncommon for smooth cordgrass to produce 8’ to 10’ of lateral spread in one growing season, Depending on site conditions and the planting objective, two rows of smooth cordgrass are occasionally planted, A two-row planting will provide quicker and denser short-term coverage than a single-row planting, If two rows are planted, rows should be parallel to each other and about 5’ apart using the same plant spacing within row as that of a single row, The first row should be placed slightly above the mean tide elevation and the second row 5’ below the first, Plants within the two rows should be staggered on center so that plants alternate between spaces, Interior Plantings: In addition to planting shorelines, smooth cordgrass can also be used along terraces, levees, across mudflats and dredge-fill sites, The planting configuration should be designed to provide maximum reduction in fetch lengths, Rows can be placed across shallow water exchange points to create a passive hydrologic barrier that will slow tidal exchange and trap suspended sediments, Planting large areas generally will require a significantly large number of plants, Where applicable, plugs can be used and placed in a row-column configuration, The row and plant spacing can vary from a few feet to many, depending on the objective of the planting, the target rate for coverage, and available resources, Planting Methods: When planting trade-gallons, transplants should be planted in a dug hole, Post-hole diggers, gas drills with modified bits, or any other methods of digging are satisfactory, The planting hole should be the same size or only slightly larger than the root-ball and deep enough so that the top of the root-ball is flush or slightly below ground, The top of the root-ball should not protrude above nor be more than 2” below normal ground, The planting hole should be tightly closed around the plant to prevent the plant from wobbling and plants should remain erect after planting, Planting sites where high wave energy is a problem may require the addition of a plant anchor, A plant anchor consists of ¼” mild steel re-bar bent into a crosier hook (candy-cane shape) and pushed down into the soil so that hook lays across the root-ball, pinning it to the ground, Anchors are generally about 30” in overall length and will add to the cost of the planting, However, anchors are generally necessary at unusually problematic sites to prevent plants from washing out, When planting bare-root plugs, holes need only be approximately 3” in diameter and deep enough to cover the roots, Any style of tool that will punch a hole this size such as a dibble bar will work, Cupping the roots of the plug in hand and pushing down into the mud carefully will also work in more fluid soils, There are no plant anchors for plugs, and in practice plugs should not be used at any site where wave energy is a factor, Fertilization: There is no clear consensus on the effectiveness of fertilizer when used in saturated and/or anaerobic soils, However, the additional cost of fertilizer is a small investment given the overall cost involved in vegetative restoration, High nitrogen slow-release fertilizer tablets will add approximately ,08 to ,10 cents to the cost of an individual plant, Slow-release fertilizer tablets are commercially available in a range of weights and analyses, Recommended tablet weight should be between 15 and 25 grams and have a nitrogen content of not less than 15% or more than 30%, When using tablets with trade-gallon plants, push the tablet into the top 3” of the root-ball immediately prior to or immediately after planting the transplant, The resulting hole should be pinched closed, When using tablets with bare-root plugs, drop the tablet in the planting hole prior to inserting the plug, Cultivars, Improved and Selected Materials (and area of origin) There are two known cultivars, ‘Vermilion’ and ‘Bayshore’, Vermilion was released in 1989 for use in the Gulf of Mexico northern basin, and Bayshore was released in 1992 for use on the Atlantic Coast, The Natural Resources Conservation Service Plant Materials Program released both, Plant materials are generally obtained from two sources, a donor wetland site or commercial nurseries, The use of donor wetlands to obtain young plants will eventually affect the health and vigor of the donor stand regardless of the care taken in frequency, spacing, and location of plant removal, In addition, the removal of plant materials without the applicable permits may be in violation of standing state and federal regulations, Removing plant materials from donor stands is not recommended, Nursery-grown stock is generally the most reliable and ecologically appropriate way to obtain plant materials, There are a number of commercial nurseries that produce and maintain smooth cordgrass transplants, Trade-gallon and vegetative plugs are the two most common sizes, however most nurseries will contract for other container sizes, Use soil moisture sensors to measure the soil moisture of Sporobolus alterniflorus (Loisel.) P.M. Peterson & Saarela., Smooth cordgrass seed is currently not commercially available, Vegetative specifications should be used to tailor plant material quality and quantity to a specific project, These specifications should include acceptable sources, cultivars, ecotypes, plant size, stem height, container specifications, and extent of root development, In addition, other requirements such as climatic hardening, salt hardening, procedures for transportation and handling are commonly included, A list of commercial wetland plant nurseries and assistance in developing plant material specifications is available from the Natural Resources Conservation Service in Louisiana,

Fact Sheet

Alternate Names

Saltmarsh cordgrass, oystergrass, and saltwater cordgrass

Uses

Smooth cordgrass is the dominant emergent grass species found growing along tidal salt marshes of the Atlantic and Gulf coasts. It is utilized extensively for erosion control along shorelines, canal banks, levees, and other areas of soil water interface. Smooth cordgrass is an effective soil stabilizer used on interior tidal mudflats, dredge-fill sites, and other areas of loose and unconsolidated soils associated with marsh restoration. Under natural conditions on tidal marshes, vigorous stands of this grass will absorb wave energy and screen suspended solids from intertidal waters, while uptaking available nutrients in the sediments. As sediments accumulate, this plant will spread away from the bank. It will tolerate petroleum contaminated soils. Smooth cordgrass provides food and cover to a number of marsh birds and mammals and is recognized as an important forage species for livestock producers along the central gulf coast.

Adaptation and Distribution

Distribution

Distribution

Smooth cordgrass colonies tend to grow parallel to and continuous along shorelines; the width and thickness of vegetative colonies are controlled by a number of site specific conditions such as elevation, shoreline slope, and frequency, depth and duration of flooding. It is commonly found growing on open coastal marshes between high and low tides from Newfoundland south to Florida and Texas. This grass can be found growing on sandy aerobic or anaerobic soils with pHs ranging from 3.7 to 7.9. Smooth cordgrass will tolerate regular inundations with 0 to 35 parts per thousand salinity. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website. It is not native along the U.S. west coast.

Establishment

Due to sparse and irregular seed production, smooth cordgrass is usually propagated by vegetative stem divisions. Depending on the energy effecting the planting site, either containerized (for high impact sites) or bare root (for mild impact sites) plants can be utilized. Since most marsh sites are irregular and difficult to access, hand planting is normally employed, using spades, dibbles, or planting bars. If site conditions are adequate, planting can be carried out with a mechanical, tractor drawn transplanter. Plant spacing should be between 18 and 72 inches; 2 to 10 feet of lateral spread can be expected annually. Smooth cordgrass grows at elevations ranging from mean high tide and above. Planting at an excessively low elevation will result in failure due to drowning and/or uprooting where wave energy is too high. Plantings in deeper water have been successful, but plants are slow to anchor and vegetative cover is sparse. Optimum water depths for establishing plants are 1 to 18 inches. Shoreline plantings are typically planted as a single or double row running parallel to the shoreline. Transplants should be planted at the mid-point between the high and low tide elevation. Plant spacing within the row will vary according to the size of the transplant materials being used and the rate at which full coverage is desired. Open water area plantings across mudflats and dredge fill sites should be designed to provide the greatest reduction in fetch length. Rows can be placed across shallow water exchange points to create a passive hydrologic barrier that will slow tidal exchange and trap suspended sediments. In nursery rows, plants of smooth cordgrass should be spaced 12 to 24 inches apart. Under ideal nursery conditions, each planting unit will establish stands containing 25 culms per square foot. Extensive weed control is essential to producing quality nursery grown plants.

Management

Stem and rhizome growth of this grass respond well to applications of a well balanced commercial fertilizers. The addition of 300-500 lbs/acre of 10-10-10 fertilizer to a planting site or nursery bed is adequate to stimulate growth and development. High nitrogen slow-release fertilizer tables may be used with container grown plants and bare root transplants. Plants propagated under nursery conditions are easily under cut and uplifted for distribution. On field sites there are a number of site-specific elements that should be considered when working with smooth cordgrass. This include; plant smothering from floating debris; herbivore grazing damage; poor water circulation; soil load bearing properties; and shoreline configuration.

Pests and Potential Problems

Non-threatening rust-like fungi (orange fruiting bodies on leaves) are commonly found on smooth cordgrass. Flower beetles may limit seed production. The sugar cane borer can cause the decline and death of stems. In areas where nutria (Myocaster coypus) is a problem new planting may need to be protected from predation. Cultivars, Improved, and Selected Materials (and area of origin) There are 2 named varieties available on the commercial market. In 1992, ‘Bayshore’ (Maryland) smooth cordgrass was released for use on Atlantic coastal areas by the Cape May Plant Material Center, in Cape May Court House, New Jersey. In 1989 ‘Vermilion’ (Louisiana) was selected and released by the Golden Meadows Plant Materials Center in Galliano, Louisiana for use in the Gulf coastal areas. Other sources of local ecotypes are available from commercial nurseries.
