Rydgren&al_OrdinationResults

The DCA (four axes) and GNMDS (3-dimensional solution) ordination results of the species compositional data from the 1031 plots. These data were collected in 80 permanently marked plots (8 plots in each of 10 blocks) in a boreal forest in SE Norway over the years 1993-2003, 2005, and 2011.Nine plots were devoid of species in 1994, The plots were experimentally disturbed before after 1993. The treatments were: T1 (removal of vegetation), T2 (removal of vegetation and the litter layer), T3 (removal of vegetation, the litter, and the mor soil layers), T4 and T5 (removal of vegetation, organic, and bleached soil layers; with T4 bordering intact vegetation on two sides, whereas T5 had a minimum distance of 0.5 m to intact vegetation). Three of the plots in each block served as controls (C).
