The semi-mobile coastal sand dune system El Morro de La Mancha at the Gulf of Mexico was studied phytosociologically and ecologically. The floristic gradient resulting from a relevé ordination was correlated with the amount of sand movement occurring on the site of each relevé, and the topography of the dune.

The gradient manifested in the ordination represents the transition from the more mobile parts of the dunes to the more stable ones. It can be interpreted as a progressive stabilization during which sand movement decreases.Chamaecrista chamaecristoides,Palafoxia lindenii andCroton punctatus were found to inhabit the sites with considerable sand movement. The first species tolerates both erosion and accretion; the other two were only found in sites of sand accumulation. On the other hand grasslands and scrub were found on sites without any sand movement. Sand movement should be considered among the most important factors that affect the distribution of communities in sand dunes.
