Figure 2From: Effects of human trampling on abundance and diversity of vascular plants, bryophytes and lichens in alpine heath vegetation, Northern Sweden Abundance, number of species, Simpson’s diversity index (D) and Brillouin evenness (HBe) for species in the canopy and understory at three different distances from the hiking trail in the Latnjavagge valley, northern Sweden. Abundance in the A) canopy layer and B) understory, number of species in the C) canopy layer, and D) in the understory, Simpson’s diversity index in the E) canopy layer, and F) understory, Brillouin evenness in the G) canopy layer and H) understory. For species and plant functional groups, see Table 1. Mean value ± 1 S.E; n =10.Back to article page
