The ecological classification method of monitoring rangeland plant communities by seral stage was developed by Dr. Daniel Uresk, Senior Research Biologist for the U.S. Forest Service. Data collection, classification, seral assignment, and monitoring are according to the method developed by Uresk (1990). Cluster and discriminant statistical techniques used to analyze field-collected data determined the presence of three to four seral stages defined by relationships of key plant variables for each type. Accuracy is 90% or greater for each type. The following publication, which determined seral stages on mixed-grass prairie in South Dakota, presented the original concept. It is the source document for the procedures presented for all grassland and woodland vegetation types on this web page.(description)
