Abstract
ABSTRACT The objective of this study was to identify, characterize and map an area for its different types of direct and indirect use of native vegetation of sandy coastal plains (Restinga) at “Praia das Neves”, a district of the municipality of Presidente Kennedy, state of Espirito Santo, Brazil. Data were collected on site using an orthophotomosaic provided by the State Environmental Institute (IEMA) on a 1:35,000 scale, where plant formations of sandy coastal plains were identified and mapped. Six phytophysiognomies were categorized by the following surveying: Halophyte/Creeping-Psamophyte, Open Scrub Palm, Low Closed Thicket, Open Scrub, Non-Flooded Forest and Herbaceous Swamp. Vegetation portions were fragmented due to use for real estate dynamics and cattle raising activity. Among the most prominent and supplied goods are wood exploitation, vegetable products for food and fresh water supply. Furthermore, the services identified are water resource maintenance and ecological functions provided by sandy coastal plain phytophysiognomies.

The ways an ecosystem can be used are divided into two large groups: being of use and non-use value
Through analyses made in “Praia das Neves”, it was possible to recognize six different “Restinga” phytophysiognomies distributed in its coastal zone: Halophyte/Creeping-Psamophyte, Open Scrub Palm, Low Closed Thicket, Open Scrub, Non-Flooded Forest and Herbaceous Swamp, as well as delimited areas that suffer some type of anthropic intervention (Figure 3)

Summary
The ways an ecosystem can be used are divided into two large groups: being of use and non-use value. Goods associated with an ecosystem are directly related to use by consumption (direct use), such as the consumption of plant species for therapeutic or food purposes, being a biological approach (Dias et al, 2014; Soares, 2002). When at ecosystem level and not individual organism, the supply is non-consumption or provision of environmental services. These are only possible to be provided by conservation of the entire ecosystem (Dias & Soares, 2008). Examples of such use are forests for maintaining water sources and nutrient stocks, which vary according to each ecosystem, such as mangrove and sandy coastal plains (Restinga) (Soares, 2002)
