Plant Community Nomenclature
Plant communities and associations are named on the basis of dominant species in the various layers.
Layers are subdivisions of vegetation within a plant community or association based on height (Figure 1).
Plant Community Nomenclature
Plant communities and associations are named on the basis of dominant species in the various layers.
Layers are subdivisions of vegetation within a plant community or association based on height (Figure 1).
They are placed into the categories of trees, shrubs, forbs and grasses.
Plant Community Characteristics
Plant communities have 8 important characteristics:
a. Composition f. Ecotonesb. Structure g. Productivityc. Dominance h. Influenced. Physiognomye. Indicators
Factors Affecting Plant Community Distribution
There are six basic factors that control plant distribution:
a. Edaphicb. Bioticc. Pyric (fire)d. Climatice. Plagic (man) f. Chronologic
Plant Community Classification There are seven general steps involved in
plant community classification:1. Review the existing literature on the
vegetation which will be classified.2. Obtain aerial photographs of the area.3. On the basis of aerial photographs and visual
examination, delimit the possible plant communities (use what appear to be dominant species in each community for naming).
General steps involved in plant community classification cont.4. Transfer the data to a topographic map.5. Stratify each community and sample for
plant cover and frequency (avoid ecotones in sampling).
6. Evaluate the degree of association between communities.
7. Rename and remap the communities on the basis of analysis; shade ecotonal areas.
