A state and transition classification for mixed grass prairie habit types. (Symposium).
Existing plot data were used for the classification to take advantage of past sampling and avoid the high costs of acquiring new data. Over 4,000 plot records from various sampling efforts during the period 1987-1999 were screened for accuracy and completeness. Of these, 2,467 acceptable plot records were sorted by habitat type and grouped into dominance types based on dominant and co-dominant species. Dominance types were grouped based on plant functional characteristics (annual, perennial, biennial; warm season, cool season; short-, mid- , or tall-grass) of the dominant species. The classification resulted in 55 vegetation states for eight grassland habitat types and 52 vegetation states for 13 shrubland habitat types. The classification provides resource managers information about capability of habitat types to support different plant communities and to evaluate their influence on ecological functions.
