AT LA DUNE DE BOUCTOUCHE
PLANTS
The most important plant here at the Dune and to the coastal environment would be Marram grass, locally known as Dune grass! This long, slender grass grows up to one meter tall with roots plunging between two and four meters into the sand and beach cobble. This depth helps to stabilize the shifting sands from storms. Marram grass is termed as a halophyte, meaning it can shrug off the effects of salt spray and salt water amongst its roots. This is done through special adaptation mechanisms, ranging from special glands which exude the salt to special leaf coatings that reduce the amount of salt the plant takes in. Only 1-2% of the worlds' flora are halophytes. In addition to being salt tolerant, Marram grass is also tolerant to very cold winter temperatures, but it cannot withstand human disturbances such as walking or driving.
