Abstract

This is a dataset containing structural attributes of a degraded edge of a tropical seasonal semideciduous forest fragment in the Atlantic Forest of southeastern Brazil. We collected data in 36 plots of approximately 45 m x 44 m each, of which 12 had undergone climber cutting (cutting), 12 climber cutting in combination with planting of native tree species’ seedlings (cutting+planting), and 12 plots had not been managed (control). Climber cutting was conducted on a yearly basis since 2014 and data on trees, saplings, and climbers were collected at different moments in time along an eight-year period. We calculated tree basal area (m2.ha-1) using the stem diameter at breast height (DBH) measured for each large living tree (DBH ≥ 4.8 cm), tree density (ind.ha-1) using the number of large living trees, and percentage of large dead trees in relation to large living trees. We then calculated tree sapling (DBH < 4.8 cm and total height ≥ 50 cm) density (ind.ha-1) using the number of saplings and sapling richness (number of species). Last, we calculated climber density (ind.ha-1) using the number of climbers longer than 1 m and climber basal area (m2.ha-1) using the stem diameter measured 1 m away from the rooting point. Data on saplings and climbers were collected in 3 m x 15 m subplots positioned at the centre of each of the 36 plots. In the datafile, we present the variable values per plot.
