Embryo Dunes
 

Sand accumulation which persists above the high tide line of normal tides may be suitable for colonisation by the first perennial plants in dune succession which are specialised grasses. The most common is

Sand Couch Elytrigia juncea.
This species differs from Marram (see mobile dunes) in being smaller and less stiff and sharp. The ligule is very short (see a grass identification guide for explanation of this characteristic).
Lyme grass Leymus arenarius
is also widespread on the Sefton Coast. It is another large grass and is easily distinguished by having a very broad blue-green leaf.

Both of these grasses are able to grow upwards through accumulating wind-blown sand and as a result low, hummocky dunes are formed. The substrate is still extremely inhospitable to plant growth (see vegetation and soil data relating to Quadrat 1).
