Publication In areas where it has established of its own accord, or where conservation values are being degraded, it is considered a weed. from Shark Bay to Cape Naturaliste) and South-West Capes (i.e. perennial) grass growing 0.5-1.2 m tall. Ammophila Host → The outer epidermis (outer circle) consists of a layer of thick cuticle and layers of thick walled sclerenchyma (red), while the inner epidermis is folded and hairy (red) to trap water vapour. Research in California has shown that dense stands of marram grass (Ammophila arenaria) are excluding many native plants and animals, including many rare species. These sites are frequently overgrown by marram grass (Ammophila arenaria) and it is possible that this process is contributing to the decline in hooded plover numbers in Tasmania. The spike-like seed-heads (i.e. https://florabase.dpaw.wa.gov.au/, Grazyna Paczkowska, Able to trap sand and build dunes at rates Culms erect, or geniculately ascending; 50-120 cm long. nodes). Fl. a lemma and palea), three stamens (4-7 mm long) and an ovary topped with a feathery two-branched stigma. It has been extensively planted as a sand binder on coastal sand dunes in the southern parts of Australia, but has spread from these plantings and is replacing native sand dune species. symbiotic nitrogen-fixing bacteria within stems and rhizomes that may contribute Alternatively spray with 1% glyphosate + penetrant. Angew Pflanzensoziol, 20:5-53. Sandy conditions drain water quickly, and very windy conditions will further increase rates of transpiration. Special motor cells (hinge) on the upper surface of the leaf are responsible for the inward rolling of leaves. impact of exotic dune grass species on foredune development in Australia and New Growth and patterns of dry matter and nitrogen allocation as influenced by nitrogen supply. What follows has been taken from Phil Gates' blog beyondthhuman eye. The dense, spiky tufts of Marram grass are a familiar sight on our windswept coasts. The plant produces ... *Ammophila arenaria MARRAM GRASS (L.) Link Habit Flowers Habit Distribution. Description: Densely tufted perennial to 1.2 m high; culms rigid, few-noded, smooth. floret). The photograph shows a stained, thin cross section of the leaf of marram grass Ammophila arenaria. 2. Ammophila arenaria is a coarse, perennial grass growing in small tufts connected by deep, tough, extensively creeping rhizomes. Light micrograph of a transverse section through a leaf of Ammophila arenaria (Magnification x10 at 35mm size). C. (2004) Endophytic nitrogen fixation in dune grasses (, Hilton, M., Duncan, M. & Jul, A. A weed of beaches, dry coastal vegetation and sand dunes in the temperate regions of Australia. 460-466. Segments of its underground stems (i.e. In the laboratory, an open system gas analysis apparatus was used to examine the gas exchange characteristics of blades as influenced by nitrogen supply. ligule) 10-30 mm long, which is often partially split in two. Out-competes native Geographic subdivisions for Ammophila arenaria: NCo, CCo, SCo, s ChI (San Nicolas Island) MAP CONTROLS 1. Seed set, viablility and survival is Leaf blade width 0.5–8 mm ... Ammophila champlainensis has been treated by many past authors as an endemic of Lake Champlain. Rhizomes elongated. (2004) Marram grass Ammophila arenaria removal and dune restoration to enhance nesting habitat of Chatham Island oystercacther Haematopus chathamensis, Chatham Islands, New Zealand. Marram grass (Ammophila arenaria) also threatens sand dune communities on the eastern and western coasts of the USA. These differences in traits across the dune environment point to Leaf-blades convolute; 20–60 cm long; 2–6 mm wide; stiff. The impact of this species on the dune systems of South Africa is said to be considerable. A. arenaria is a grass species specially adapted to growing on sand dunes. A long-lived (i.e. green, Oct to Dec or Jan. Australian Herbarium, Biodiversity and Conservation Science, species to re-establish. It forms dense tussocky tufts and also spreads via creeping underground stems (i.e. In Ammophila arenaria, there is tight upward folding of the leaf and also the sheltered situated of the stomata in furrows, greatly reduce air movement over stomatal areas. The floret has two floral bracts (i.e. Family Poaceae. Widely naturalised in the coastal districts of southern Australia. Cape Naturaliste to Albany) regions of this state. The natural loss of water through transpiration is not desirable in a very dry landscape, and marram grass has developed particular adaptations to help it deal with this. In the image below, you can see a leaf from the beach grass Ammophila rolled in on itself. removes thatch and stimulates regrowth, creating ideal conditions for effective Local Government Areas (LGAs): Ligule an eciliate membrane; 10–30 mm long. Poaceae Barnhart changing topography, adversely affecting long term development of coastal The leaves consist of a leaf sheath the encloses the stem and a rigid and spreading leaf blade. In the xerophytic grasses, the motor cells are well evolved. Resprouts, stimulates vigorous regrowth. This species is not declared or considered noxious by any state or territory government in Australia. pubescent), while their undersides and hairless (i.e. Plants For example, the population size and diversity of sand-burrowing arthropods were found to decrease as marram grass (Ammophila arenaria ) cover increased. the leaf blade is hairless, but it may have tiny prickles that give it a sand-papery feel Leaf blade length 15–80 cm Australian Flora. For example, marram grass (Ammophila arenaria) tussocks are more successful at trapping wind-blown sand than the native plants that it replaces, causing greater dune building around plants. Species information. In exotics, leaf size was larger at greater distances from the high tide mark, as was plant height in A. arenaria. Native beach plants that are most commonly replaced include beach spinifex (Spinifex sericeus), beach fescue (Austrofestuca littoralis), dune sedge (Carex pumila) and glistening saltbush (Atriplex billardierei). Marram grass under the microscope. Leaf-blade surface ribbed; pubescent; hairy adaxially. 2. (2014). Category. Functional traits of common New Zealand foredune species at New Brighton, Canterbury. The leaf blade has the ability to inroll to form a cylinder, a process that protects the leaf from desiccation during periods of drought. Grass. Nutrient and productivity relations of the dune grasses Ammophila arenaria and Elymus mollis : II. It displaces native dune species and significantly alters the morphology of dune systems in this country too. The seeds may be spread by wind, water and animals. Perennial; caespitose. Native to northern Africa, Europe and western Asia. The effects of various perturbations on leaf populations of Ammophila arenaria in various stages of a sand dune sere were studied over a period of almost two years. vegetation and interferes with the natural dynamics of dune systems, including situation or state. European beachgrass grows more densely than native American dunegrass (Leymus mollis), trapping passing sand and creating … These leaf blades (20-70 cm long and 1-2.5 mm wide) are usually tightly inrolled (i.e. Summary. glumes) remaining on the seed-head and the floret being dispersed. Busselton, Jerramungup. According to GrassBase - The Online World Grass Flora under the synonym Ammophila arenaria. Ammophila leaf. The upright (i.e. Fire may provide an effective window for control, as it Leaf-blade apex pungent. The purpose of this research was to investigate the influence of nitrogen availability on growth and the patterns of dry matter and nitrogen allocation of the dune grasses Ammophila arenaria and Elymus mollis.Plants were grown from rhizome segments under near-ambient coastal conditions and received either high or low supplies of nitrogen. Leaves with sheaths overlapping; ligule narrow, firm, 2-fid, 2–3 cm long; blade sharp-pointed, inrolled, to 6 mm wide when flattened, greyish green. rhizomes) and seeds may also be dispersed in contaminated sand. Magnoliophyta California, Oregon and Washington) and Hawaii. in Tasman National Park) and elsewhere (i.e. (, Moore, P. & Davis, A. Coastal sand dune systems in other parts of the world are also being threatened by the establishment of marram grass (Ammophila arenaria). Education. Leaf-blade apex pungent. The upper epidermis is now highly invaginated and located on the inside of the rolled leaf. They consist of a pair of bracts (i.e. Leaf-blades convolute; 20–60 cm long; 2–6 mm wide; stiff. The control methods referred to in this fact sheet should be used in accordance with the restrictions (federal and state legislation, and local government laws) directly or indirectly related to each control method.
