Similarly, Gaylussacia baccata
occurs on nearly 80% of unplowed but only 21% of plowed plots.
Vegetatively, both groups had a distinct Gaylussacia baccata shrub layer.
Vegetationally, these two groups were similar to groups (i) and (j) in that they had a distinct Gaylussacia baccata shrub layer.
Wet sites lacked Gaylussacia baccata, a widespread species in the Albany, Schunnemunk and Shawangunk plots which clustered in the center of the ordination.
The shrub layer at Lake Maratanza was dominated by Gaylussacia baccata (52% cover) and Vaccinium pallidum (24% cover) while at the Ice Caves Gaylussacia (87% cover) shared dominance with Kalmia angustifolium (38% cover).
Gaylussacia baccata decreases in cover along the first axis in those plots where exposed rock is most widespread; its greatest cover is on the sandy Albany site to the left of the ordination.
Cluster 2 plots occurred on Oak Island on Potsdam sandstone, and were similar to those in cluster 1 but with a more dense shrub layer of Gaylussacia baccata.
These plots had pitch pine, white pine or red maple (Acer rubrum) as overstory dominants and a shrub layer dominated by Gaylussacia baccata and Vaccinium angustifolium.
Gaylussacia baccata and Vaccinium angustifolium were a major component of the ericaceous dry-mesic cluster with combined cover values of up to 145% (before being relativized).
Plots to the right of the line contained from 30% to over 100% absolute cover by Gaylussacia baccata, Vaccinium angustifolium, V.
Clusters 10 and 11 were on mesic to wet-mesic sites with a dominant shrub layer of Vaccinium corymbosum and Gaylussacia baccata and, in cluster 11, Sphagnum moss and Virginia chain fern (Woodwardia virginica) in the ground layer.
