From: High canopy cover of invasive Acer negundo L. affects ground vegetation taxonomic richness
Average rates (± SE, ± 95CI) of canopy cover of different species of native (green plots) and alien (whitr and pink plots) tree species; rare species—the indication for a group of plots dominated by species rarely found in the studied site (Amelanchier spicata, Caragana arborescens, Cotoneaster lucidus, Crataegus sanguinea, Larix sibirica, Lonicera xylostella, Tilia cordata).
