Vegetation Summary


Plant species that are present in > 20% of the Association’s constituent plots are included in the stratum summaries.

Note that in this display version of CNVC00001, species have been omitted from the vegetation summary for brevity. For the full version of CNVC00001, see Explore the Hierarchy.

List of Species


Bolding indicates species that are diagnostic for the Association or subassociation. These species appear in the name of the Association or subassociation, and their constancy or abundance differentiates one vegetation type from another. See "diagnostic species" in the Glossary for more information.

The species listed occur in more than 20% of the sample plots (i.e., have greater than 20% presence). They are listed in descending order of presence. Where subassociations occur, presence is calculated for each subassociation, so species with >20% presence in a subassociation are listed although they may not meet that threshold for the Association.

See Botanical Nomenclature for botanical sources, synonyms and common names.

Stratum Cover Statistics


The 10th percentile, 25th percentile, mean, 75th percentile and 90th percentile of total cover per stratum. These statistics are calculated by stratum, from combined species % cover totals for each plot. Where subassociations occur, separate statistics are provided for the total association and for subassociations.

Understory Woody Shrubs and Regenerating Trees


Shrub species and regenerating tree species that are less than 5 m in height. A shrub is a perennial woody plant that generally has several erect or prostrate stems which give it a bushy appearance. Dwarf shrubs, which have a prostrate growth form and are no higher than 10 cm, are included in the herb layer.

Understory Herbs and Dwarf Shrubs


Ferns, forbs (broadleaved herbs), graminoids (grasses, sedges and rushes) and dwarf shrubs (woody plants that have a prostrate growth form and occur within 10 cm of the ground).

Bryophytes and Lichens


Bryophytes (non-vascular plants including mosses, liverworts and hornworts) and lichens

% Cover and % Presence


Cover is the area of ground covered by plants of one or more species. % Cover is the average percent cover of a species within the plots in which it occurs in the Association / subassociation (i.e., characteristic cover).

% Presence is the percent frequency occurrence for the species within the total plots in the Association / subassociation.
