Im Gartenbereich bietet sich der Strandhafer besonders in Gärten an, die einen Strand- bzw. Share Tweet A. arenaria is a grass species specially adapted to growing on sand dunes. [18] nfortunately, the use of NaCl to control a weedy species is illegal as it is not registered as a pesticide in the state of California. By contrast variation in Ammophila arenariaon dunes exhibits high levels of phenotypic flexibility, growth in a range of environments indicating that plants from fore-dune populations are higher ‘responders’ than those from mature dunes. 1973. The adaptation of A. arenaria to sand accretion is well known. The use of alternate salts has not been addressed. 7001, Australia. Es werden derzeit zwei Unterarten unterschieden:[7]. Marine beach and dune plant communities. Jahrhunderts wurde der Strandhafer nach Australien, Neuseeland, Nordamerika (1868, San Francisco) und Japan zum Zweck von Dünenbefestigungen eingeführt und gepflanzt. Since the sand supply is reduced by the fully colonised foredune, the vigour of A. arenaria generally declines in the "Mixed Ammophiletum" community. Nature.

On the physiological Marram grass (Ammophila arenaria) of dune tops with its hard, in-rolled leaves, appears to be the embodiment of drought resistance. Die Blätter haben eine dicke Kutikula und Epidermis. Earlier small-scale experiments at the preserve found that a 2% solution of Roundup, applied during anthesis, resulted in 60 to 100% mortality. Mem. [15] Mature seeds are dispersed in September. [3][4], Non-native habitat A. arenaria has been introduced to stabilize sand on the west coast of the United States since the early 1900s. Beach and dune. Ammophila arenaria and A. breviligulata (American beachgrass) can be distinguished by their ligules, those of A. arenaria being thinner and longer ligules (10-30 mm) versus the firmer and shorter ligules (1-3 mm) of A. breviligulata. Checklists containing Ammophila arundinacea Host. In northern California, A. arenaria changes the geomorphology of the foredune community from a gentle slope to a vertical wall which prevents adequate sand movement from beach to interior dunes. Das Gras ist auf diese Weise maßgeblich an der Bildung der bis zu 25 Meter hohen Weißdünen beteiligt. is a genus of flowering plants consisting of two or three very similar species of grasses. 1977. It is an open community with only a moderate amount of bare sand. Search this record. and M.G. 1966. The Habitat Restoration Program of the Menzies' Wallflower Research Project (MWRP) at Humboldt State University, Arcata, California, is currently investigating three methods of A. arenaria control: salt application, use of herbicides, and manual removal. Well-formed: Y Recommended: N NBN ID code: NBNSYS0000141606. Yemm. [3][4], In native habitats, A. arenaria alone makes up the foredune plant community.

The anatomy and the physiognomy of this plant enable it a perfect adaptation for hydric and salt stress in these dunes. Its strong rhizomes are capable of extending deep into sandy soil. 1973. Not only is transpiration reduced to a minimum, but also the deep root systems are able to access water from the lower moist layers in the dunes. ), Articles of the Oregon Coastal Zone Management Association, Inc. Newport, Oregon. 2012. A study of European beachgrass. An introduction to beach and dune physical and biological processes. is a genus consisting of two or three very similar species of grasses; common names for these grasses include Marram Grass, [8], At Point Reyes, California, Barbour (1977)[13] found that A. arenaria had twice the root density of Elymus at every depth measured from 1-5 m. Differences in root systems may provide A. arenaria greater resistance to drought and more efficient means of tapping soil moisture. Die Art bildet sowohl horizontale als auch vertikale Rhizome aus. Der Strandhafer blüht von Juni bis Juli. Rapid vertical growth of the grass initiates dune formation, and the grass spreads rapidly in all directions by horizontal rhizomes. The most typical plant is Ammophila arenaria (or Marram Grass) which plays numerous ecological roles. For a better understanding of the adaptation of Ammophila arenaria, a morphometric study is necessary. [8] Research on Elymus and Ammophila ssp. Ammophila (synonymous with Psamma P. Currently, where dominated by A. arenaria, the foredune topography has changed to a steep slope, and the orientation of the dunes is parallel to the coast. Die meisten rezenten Strandhafer-Bestände in Sandlebensräumen sind darauf zurückzuführen. Die Schadwirkung wird mit einem Abnehmen von auf das Wurzelwachstum günstig wirkender Pilze, sogenannter Mykorrhiza, mit zunehmender Alterung und Versauerung der Grau- und Braundünenstandorte in Zusammenhang gebracht. The marram grass develops on a sandy soil structure. DeJong, and B.M. Ecology 58, 1171 – 1175. Sand deposition stimulates growth of A. arenaria, which in turn encourages more sand deposition. Pavlik. Perennial species invading the early stages of primary successions face constant, and often rapid, change in their biotic and abiotic environment. Die zwei Hüllspelzen sind lanzettlich zugespitzt und rau, die untere ist einadrig, die obere drei- bis fünfadrig. Ammophila arenaria creates higher, more hummocky peaked dunes (Hesp, 2002), which can easily withstand flooding (Seabloom, Ruggiero, Hacker, Mull, & Zarnetske, 2013). is a genus of flowering plants consisting of two or three very similar species of grasses. It is not to be confused with Ammophila (wasp). An Küsten und auf Inseln kommt dem Gras eine besondere Rolle für den Aufbau und die Stabilität von Dünen zu. Ammophila arenaria has been introduced in many countries, because of its excellent dune building capabilities (Konlechner, Hilton, & Orlovich, 2013). Burial stimulates vertical growth. In A.J. In Fitzpatrick, K. B., (ed. Beauv.) Control of this introduced species is necessary to protect the limited occurrences of viable natural sand dune systems along our coastlines. It is a perennial grass forming stiff, hardy clumps of erect stems up to 1.2 metres (3.9 ft) in height. Part I. J. Ecology. [2], Radioactive carbon studies suggest that Ammophila ssp. Int. (ed.

Dieses führte schließlich zu einem Verlust von Ackerflächen und Siedlungen. There is strong observational evidence that marram grass Ammophila arenaria transforms vegetation when it invades temperate coastal sand dunes. Die Populationen des Bastards unterscheiden sich ferner in ihrer Ähnlichkeit zu den Elternarten. Munz, P.A., and D.D. Willis, A.J. Odum. Barbour, M. 1977. 1952. [5][6][7][8] When planted on disturbed dunes or bare sand, it has initiated dune formation in the manner described above. The common names for these grasses include marram grass, bent grass, and beachgrass.These grasses are found almost exclusively on the first line of coastal sand dunes. Following control, monitoring for new invasion may be accomplished by thorough surveys of the foredune and upper beach each month. small (250x250 max) medium (500x500 max) large ( > 500x500) Ammophila arenaria.

This mosaic community is typically found on the lee slopes of dunes, mostly on inland, less active slip faces. Ammophila arenaria occurs on coastal sand dunes throughout the world. On the physiological Die Keimlinge können sich nur in sehr geschützten Bereichen etablieren. Added protection from the wind and sand deposition results in the pattern of new growth to the lee of the existing tussocks. Influence of Ammophila arenaria on foredune plant microdistributions at Point Reyes National Seashore, California. D. Orton - Dune Brittlestem. Dort übernimmt sie die Aufgabe, die Dünen zu befestigen. A study of Pacific Coast beach vegetation [12] revealed that A. arenaria exerts more control over community competition than any other beach dominant. In this Dutch study three different methods of establishing marram were assessed: planting bundles of culms (traditional method), sowing seeds, and … Plant associes and succession cycles of the sand dune and dune slack vegetation. [14], A. arenaria is highly adapted to sand accretion. Increased human disturbance and therefore sand dune destabilization, along the coastline favours A. In the xerophytic grasses, the motor cells are well evolved. Ammophila (synonymous with Psamma P. Species biology and potential for controlling four exotic plants (, Slobodchikoff, C.N., and J.T. So weisen die britischen Bestände meist eine größere Ähnlichkeit zum Gewöhnlichen Strandhafer auf, während jene an der Ostsee eher dem Land-Reitgras gleichen. A history of the Eureka Coast Guard Station. New Phytology 74:51-58. [6][7][10] It has recently been determined that A. breviligulata, native to the dunes of the East Coast and Great Lakes and introduced to Washington and Oregon, is actually more prevalent than A. arenaria in Washington.[11]. Vegetatio 62, 273 – 278. I. It displaces native dune species and significantly alters the morphology of dune systems where it invades. (ed.

Oregon's coastal beaches and dunes: impacts, uses, and management considerations. On the morpho-anatomical level, marram grass (Ammophila arenaria L.), a typical granimeous plant of the coastal dunes, is well adapted to its biotope. Ammophila arenaria (Marram) will reach a height of 1m and a spread of 0.6m after 2-5 years. In Europe, anthesis occurs in July and August [2] but has been reported as early as May. Major (eds. 1979b. Ternyik, W.E. 1974. Well-adapted to a harsh life at the coast, its glossy, rolled-up leaves protect it from drying out. Die Erstbeschreibung der Pflanze erfolgte 1753 durch den schwedischen Naturwissenschaftler Carl von Linné in seiner Species Plantarum als Arundo arenaria (Basionym). is a genus consisting of two or three very similar species of grasses; common names for these grasses include Marram Grass, Bent Grass, and Beachgrass. Viability of seeds is low. 1. Development of a soil microflora in relation to plant succession on sand dunes, including the 'Rhizosphere' flora associated with colonizing species.

Braunton Burrows: The dune system and its vegetation. 1965. In früheren Jahrhunderten wurden die festen Blätter des Strandhafers zur Herstellung von Schnüren und Tauen, sogenannten Reepen, sowie Matten verwendet. The moisture of this substrate increases with the depth while the salinity decreases. In addition, it occupies the hummock dunes, the fields of vegetated sand dune mounds occurring inland from the foredune, and the deflation plain. Sie sind zugespitzt, glatt und kahl, aber auf der Oberseite entlang der Blattadern fein behaart. Ranwell, D. 1959. Sie sind versteift und deshalb sehr hart. 1953. The foredunes were low and rose above the beach with a gentle slope. The transpiration needs of dune vegetation can … J. Ecology. [8], In Oregon, Crook (1979a, 1979b)[6][7] reports that prior to the introduction of European Beachgrass there were no foredunes along the coast. [8] In Oregon, it has severely reduced the sand supply from beach to large inland dunes. (1980) Ammophila arenaria subsp.
