  Poaceae - Wikipedia, the free encyclopedia
Grass blades grow at the base of the blade and not from growing tips: this gives the grasses a competitive edge under pressure of grazing herbivores, as the growing points are less likely to be damaged.
Grasses are used for construction; larger bamboos and Arundo donax have stout culms that can be used in a manner similar to timber, and grass roots stabilize the sod of sod houses.
Grasses are the primary plant used in lawns, which themselves derive from grazed grasslands in Europe.

 Marram grass - Wikipedia, the free encyclopedia
Marram Grass or Beach Grass is a genus of two species of grass growing almost exclusively on coastal sand dunes, where rhizomes on its extensive root system allow it to survive in a very harsh and windswept ecosystem.
Marram has adapted to the harsh conditions of the Main Ridge sand dunes by having leaves which can roll into a tube in dry weather to reduce surface area.
They are also shiny and aligned to wind direction in order to reduce transpiration rates and minimise salt deposition from sea spray.

Marram is the common name for a beach grass that grows on the sandy coasts of Europe, North America, and North Africa and is also known as psamma or sand reed.
These course and hardy grasses grow in tufts producing tightly rolled spike-like leaves that are naturally resistant to wind and salt spray.
Beach grass has the unusually ability to grow most vigorously on seaward slopes where it is regularly buried by windblown sands.

 Propagating dune grasses by cultivation in a nursery in Norderney, Germany
It is more vigorous than Marram Grass, it still grows on the older dunes and it seems to be more robust and does not need as many nutrients, but because stocks for cutting are limited, it is not used extensively for dune conservation.
The superiority of the Baltic Marram Grass was established.
Because of the great success of the Baltic Marram, a method for field propagation has been developed, further in 1990 an area of 2.8 ha was set aside to propagate this grass to have a sufficient source for annual planting on Norderney.

The marram grass, on the other hand, indicated a sudden surge between the distance of 0-10 meters, a decline in density between 10-30 meters, another increase on the 30-35 meters mark, and finally, a downward trend from the 35-50 meters distance.
In regards to the difference between the expected marram grass density and the gathered data, the variation, quite possibly, was caused by several factors that disturbed the landscape in this particular area.
The second reason is more logical because, as shown by the graph above, the density of the marram grass decreased as the density of the woody plants increased, indicating perhaps that the two were engaged in some sort of “food” competition.

 Beach Grass, Marram Grass (Ammophila breviligulata)
Beach grass is clearly one of the most critically important dune plants.
Its fast growing rhizomes can respond to the constantly shifting sands, enabling this species to serve as a significant sand binder, Sand reed grass (Calamovilfa longifolia) is also a common grass of the dunes, bearing tough rhizomes that allow it to perform a similar ecological role.
The latter species, which is usually a much taller plant than beach grass, can also be distinguished by its more open seed heads.
