Scope: The plots are distributed in chronosequences from 2 to 60 years, in three forest typologies: dense ombrophilous, mixed ombrophilous and deciduous seasonal, with a total of 158 plots, 10 of 100 m² and 88 of 200 m². In each plot, we measured the diameter and height of individuals with dbh >= 3 cm and above 1.5 meters high. Secondary forest in the region presents a sequence of stages recognizable from its physiognomy: shrubs, small trees, arboreal and advanced arboreal species. In each plot, all woody plants higher than 1.5m were identified to species level, either in the field or aided by taxonomists.
Abstract: The measure of the vegetation was realized to sample secondary forest distributed in the Atlantic Forest, in the south of Brazil, more precisely in the state of Santa Catarina. We sampled only secondary forests originated from abandoned agricultural fields, with no signs of degradation, because they represent the majority of regenerating forests in the region. We sampled only forests located within typical farms in the region (i.e., farms with a mosaic of regenerating forest patches, avoiding samples from isolated secondary forest patches). Our sampling did not take into consideration forest size, slope and aspect, or distance from mature forests; consequently, we did not measure such landscape variables in this paper. At each farm, we asked permission to inventory the forest. Then, the landowner was asked to explain the history of land use, and disturbance, including how long the land had been abandoned.
