These files are complementary data from the paper " Edge effect on the spatial distribution of trees in an Araucaria Rainforest fragment in Brazil”. The paper was published in Rodriguesia journal in 2018. The files are:<br> <b>Data1_Pine and Data2_Agriculture:</b> These files contain the lists of individuals measured in Pine and Agriculture plots during the field inventories from 1995 and 2013. They contain the name of the specie of each individual, the coordinates X and Y, the DBH (diameter at breast height) from 1995 and 2013 (if the individual was live in this two years), and the defined category (Living, Recruitment and/or Mortality). The data is collected as part of the Brazilian Long Term Ecological Research Program (PELD) Site 9, for what there are performed annul inventories since 1995. In these inventories all the trees with DBH ≥ 10cm are measured (at DBH), classified according to its specie, and geographically positioned. During the years of the inventories, many individuals are recruited, as well many individuals are found dead. Considering this, we classified each one in these categories, but it is possible for a same individual to be part of two categories at the same time. The coordinates are in UTM, and the datum utilized was SAD69, fuse 22 south.<br> <b>Figure1_Pine and Figure2_Agriculture:</b> These figures shown the special distribution, the Kernel density map, and the GAM (Generalized Additive Model) model of all analyzed species in Pine and Agriculture plots, considering also the categories of Living, Recruitment and Mortality. The GAM model was calculated to evaluate the relationship between number o individuals of each specie and edge distance (considering categories at each 10 meters). The Kernel density model was created using ArcMap 10.4.1, and it represents the occurrence density of each specie (for each category) in both plots.<br> <b>Table1_Pine and Table2_Agriculture: </b> In these tables are presented the values of the Spearman’s Correlation Coefficients (ρ) and the GAM statistical results, calculated to evaluate the relationship between number of individuals of each species and the edge distance in Pine and Agriculture plot. This was calculated considering the categories Living, Recruitment and Mortality of individuals.<br> <b> </b> <b>Table3_EGroup:</b> This table presents the values of the Spearman’s Correlation Coefficients (ρ) and the GAM statistical results, calculated to evaluate the relationship between number of individuals by ecological group and edge distance in Pine and Agriculture plots. These values are calculated considering the categories Living, Recruitment and Mortality of individuals. The groups are divided in LS/C (Late Secondary or climax), and P and ES (Pioneer and Early Secondary).<br>
