Summary: ABSTRACT
Restinga, an ecosystem associated with the Atlantic Forest, has different edaphic characteristics due to its fluvial-marine origin in the Quaternary, which occurred 120,000 years ago, and more recently 8,000 years B.P. Assuming that the current flora has changed in its composition in the last 20 years, and because of that the phytophysiognomies could be increased with new characteristics and that the geographic distribution of species was expanded. Thus, activities were carried out to answer the research questions, which consisted of fieldwork, bibliographic survey, search in specialized sites for species selection containing at least the physiognomy WHERE it was
collected, collector and taxonomist responsible for the determination; updated habit, name, spelling, in addition to geographic distribution, considering Brazilian municipalities and states and countries on different continents. It was necessary to consult experts to confirm species or their distribution, when there were contradictions in the different means of information. Species in Restinga were related in their vegetation formation by municipality, as well as their geographic distribution beyond the borders of Espírito Santo.
For the geographic distribution of the species, new standards were established, some of which were adjusted to the existing ones, which also served for comparisons. The flora of Restinga consists of species originating mainly from the Atlantic Forest Biome, with the vegetation of Espírito Santo being the main source for the 1151 species that make up the database. Other physiognomies are involved in the composition of the flora, with representatives from the Cerrado, Caatinga, Pantanal, Pampas, in addition to the Amazon. Among this group there are species with some type of threat, in the regional list the number is 136 and in the national one 36 of these were contemplated, with great part in Conservation Units of this state. In the organization of vegetation in the sandy plain, this is done in a differentiated way, constituting herbaceous, shrub and arboreal phytophysiognomies, which in turn are under the influence of the degree of saturation of the sandy sediment, being non-floodable, floodable and flooded, with the shrubs still having an organization with continuous vegetation or even, it is organized in thickets, with spaces between them containing species that are almost entirely herbaceous, growing
isolated, rarely in groups, with large bare spaces between them. Of these species, 34 were related as endemic to the State of Espírito Santo, but those occurring in neighboring states in the Southeast were included in Costa Atlântica Restricted ES-BA with 60 species, Costa Atlântica Restricted ES-RJ (35) and Costa Atlântica Restricted ES -MG (6). The Broad Atlantic Coast Southeast-Northeast, Broad Atlantic Coast Southeast- South and Broad Atlantic Coast North-Northeast-Southeast-South and, WHERE relevant, the endemic and non-endemic patterns were also established. Heading to the interior, the patterns of the Midwest Atlantic Coast and North Atlantic Coast are both with the endemic and non-endemic categories. For several regions of Brazil that do not fit into the others, the Atlantic Coast Wide Endemic or Atlantic Coast Non-endemic, with 34 and 402 species, respectively. The flora of Restinga in Espírito Santo was expanded, and they are mostly in Conservation Units, but it is necessary that other remaining areas are protected because they contain species that are threatened.
