Marram grass forms the first line of plants on sand dunes. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Marram grass is originally from Europe and North Africa and was introduced to New Zealand over 100 years ago for dune stabilisation, property protection and to prepare sand dunes for the planting of conifers. Surveys of the vegetation on the . Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis. PS: Came across a website for the Marram Grass Caf when Googling for this blog. In order to survive in aeolian dune environments, plants employ both avoidance and tolerance strategies to cope with environmental stresses such as high wind velocities, sand blasting, sand accretion, wind erosion, unstable substratum, high soil temperature, and nutrient deficiency (Hesp, 1991;Maun, 1994; Maun, 1998) . Physical conditions in embryo dunes are harsh. Primary succession occur on land which had no previous vegetation, including lava flows, bare rocks, and sand dunes. Your email address is used only to let the recipient know who sent the email. Over time, the mobile dunes become less stressful for plants, as death and decay of vegetation continues to add organic matter to the soil. The algae binds mud, adds organic matter, and traps sediment. Thedune surface then begins to stabilise andfiner grasses, herbs and lichens can grow.

This continues until climax community is reached. The form of dune systems will be dictated by a number of factors, including the shape of the coastline, shape of the beach . What adaptations do plants have in the two places? Tussocks of marram grass start to break up, as old marram growth is no longer being rejuvenated by burial in sand. In these acidic dunes, the collapse of old heather bushes may provide a place for young birch trees to grow. How and why do abiotic factors vary? Other xerophytic adaptations include waxy leaf coatings, the ability to drop leaves during dry periods, the ability to reposition or fold leaves to reduce sunlight absorption, and the development of a dense, hairy leaf covering.

The dunes regrow naturally, starting as baby dunes and reforming as sand collects on debris and grasses take root. The common names for these grasses include marram grass, bent grass, and beachgrass. They will vary according to the frequency of inundation (which relates to the height of the blow-out floor relative to the summer/winter water table), the pH of the ground water and the substrate, the age of the slack, and the intensity of grazing. Now that we understand the spatial organisation of coastal plants, the next step is to apply these findings to regeneration projects so that we can help plants get established," says van der Heide. In addition, marram and lyme grass have leaves that can curl into a cylinder in order to limit the loss of water in the constant wind. The coastline is a difficult place for plants to survive, thanks to all the salt and crashing waves. %PDF-1.6 % Where does marram grass grow in North Carolina? They often have deep taproots and roots at their nodes that allow them to spread, firmly anchor in the sand, and stabilize the sand against erosion.
