Ecological Restoration, Forestry, Dune StabilizationAbstract
The forestry of Pinus elliottii reached a commercial scale in the mid-1980s in the municipality of São José do Norte, RS, Brazil. With the aid of tax incentives, producers sought income from resin extraction, and the plantations expanded significantly, forming large blocks in the district of Bojuru. This study aimed to evaluate the natural regeneration of pioneer native species following the removal of P. elliottii in a dune area; assess the implementation of vegetative barriers using native species for area restoration and dune protection; and test different techniques for dune stabilization using physical barriers and clustered native plantings. The results of natural regeneration were favorable at the experimental site, unlike the seedling survival rates, which were below the levels considered ideal for restoration purposes. The dune stabilization technique using physical barriers (containment fences) proved effective on the dune crest but did not yield the same results in wet areas or those with pre-established vegetation. Dune areas adjacent to commercial plantations and lacking established vegetation are particularly vulnerable to the spread of P. elliottii seeds.
