Abstract: The restinga is a sandbank formed by sand deposits parallel to the shoreline, generally elongated in shape, produced by sedimentation processes, with different biota communities having generally marine, or estuarial, influence.The term restinga is commonly used in Brazil to describe both the coastal landscape and the associated vegetation (Silva et al., 2010).The restinga vegetation, according to the Brazilian National Council for the Environment (CONAMA, 1996), includes all the plant communities, physiognomically distinct under marine and fluvial-marine influence.These communities, distributed in mosaics, are characterized by herbaceous, shrubby and arboreal plants and also by areas naturally devoid of vegetation.Such vegetation occurs in regions of great ecological diversity, being considered edaphic communities more dependent on the soil nature and their water content than on the climate (Magnago et al., 2012).The restinga vegetation plays a fundamental role in the stabilization of sediments and maintenance of natural drainage, as well as in the preservation of resident and migratory fauna associated with the sandbank (CONAMA, 1999).The dunes are also protected by the legislation.Fixed or semi-fixed dunes have a greater pedological development associated with the settlement and increase of a vegetation cover, which provide an environmental stability by mitigating the influence of winds and, therefore, fixing it in the landscape (Pinheiro et al., 2013).Along the Middle Coast of Rio Grande do Sul State, Pinus forestry has been established since the 1970's.However, this woody invasive species spreads easily from the forestry plots, invading restinga and dune ecosystems, where it can damage the biota, when not properly handled.In the study area, Pinus spp specimens from the nearby forestry plots are invading the borders of the remnant restinga forest (Figures SI-I.1 and SI-I.2) and also expanding over the dunes and Paurá lagoon margins (Figure SI-I.3).
