Anglica can be found in almost every salt-marsh community, the distinctive situations of the community are towards the seaward fringes of marshes, on creek sides, colonising old pans in the upper-marsh zone and, more rarely, in brackish seepage areas behind sea walls. The Atriplex hastata-Suaeda maritima phase is characteristic of tidal drift. A wide variety of substrates is colonised, from extremely soft mud to shingle. There is some evidence of more rapid vegetative spread through finer material (Chater & Jones 1957).

Regn. 1926) Corillion 1953) and the naturalised alien S. alterniflora (SM5, Spartinetum alterniflorae Corillion 1953), appear to be declining and are now much restricted in their distribution. Tx. 1961. , Suaeda maritima and Puccinellia maritima occur together in various combinations as colonising vegetation towards the lower limit of saltmarshes and in open and disturbed areas at higher levels. Three communities have been distinguished according to the balance of the various components: the annual Salicornia salt-marsh (SM8, Salicornietum europaeae Warming 1906), Suaeda maritima salt-marsh (SM9, Suaedetum maritimae (Conrad 1935) Pignatti 1953) and 20 the transitional Puccinellia-Salicornia-Suaeda saltmarsh (SM10).

Cotton 1912, Carter 1932, 1933a, b, Chapman 1974, Polderman 1979, Polderman & Polderman-Hall 1980). These suggest that the concordance of algal assemblages with vascular plant communities may not be precise. In addition, algal communities appear to be subject to greater seasonal changes and, at least where the smaller species are concerned, to be organised on a finer scale. For the most part, therefore, vascular communities appear to be superimposed upon a distinct, more changeable and finer pattern of algal vegetation.
