J.P. Myers 1974 Journal [illegible] to Coast, Estancia Mielalnd 35 Km S. of Juncha by road Ptdo d Madaring Pcia de Bs.Aire Argentina 7 September (cont’) expansion of open water. Many pablum of tole arquite dry. Toward the SE, in the NE-SW approximately 2-3.5 Km (between this distance) a third type of habitat can be found: this is a series of higher NE-SW strips of sandy soil between the Spartina and tole; they are covered with grasses, which at this time of year are less than 6” high. However, judging from the presence of woody stalks, during the summer this veg. gains height to ≥30 cm. Beyond ~3.5 Km, a broad band of sand dunes develops. The majority is pure, blowing sand; altitudes of ≤10 m are reached. In some places there are sparse pablum of grass, obviously of several different kinds (one a thin, short (8 cm) grass which because it is so sparse can scarcely be seen from a distance; another is a thick bunchgrass, growing in dense pablum but with 20 cm or more of sand between each bunch, 40 cm high). There are also other types of ground cover, but very little in any given place. Toward the coast the veg. becomes more common. The dune zone (according to Instituto Geografico Militar topo map 3757-27-2) is ~3.5 km wide. The coast line runs NE-SW, paralleling the habitat strip described above. The actual beach, i.e. the strip between veg.-covered dunes and water at low tide, appears to be ~30 m wide with a steep incline. I arrived at a time of low tide, but could not discern if it was incoming or outgoing. A ledge. It is pure sand, not a hint of mud. Water was muddy, with an appreciable (for the area) surf. The tide had exposed a ledge, many feet below high tide, which runs parallel to the beach and in places creates small ponds during low tide. There was surprisingly little debris on the beach. Species list (annotated as to which zone seen in: P (pampas grass) S (Spartina), T (tole + or swamp) G (higher grassy areas) D (dunes), B (beach) O (ocean). I suspect that the strong wind decreased the number of species observed particularly in the grass and Spartina areas.
