pin points reading along elevation gradients in wetlands

This data corresponds to the reading of plant vegetation surveys conducted on plots 25x25 cm large, with 18 readings (R1 to R18) on each plot. Each count is the number of hits per species. They were recorded on 70 plots, 25 x 25cm large, placed every 20 cm along two elevation transects used as replicates (35 plots per sequence). Plots were proteted from grazing by cattle and horses. On each plot, vegetation relevés were performed along both diagonals using the pinpoint method, with a record every 4 cm. Three readings were made: on the 23-29 October, 2008 (Year 1, period 2), on the 3-12 June, 2009 (Year 2, period 1) and on the 19-20 October, 2009 (Year 2, period 2).
