Identifying and Characterizing Dominant Plants as an Indicator of Community Condition

  title={Identifying and Characterizing Dominant Plants as an Indicator of Community Condition},
  author={Christin B. Frieswyk and Carol A. Johnston and Joy B. Zedler},
Dominant species play key roles in shaping community structure, but their behavior is far from uniform. We speculated that recognition of different behaviors (determined objectively) would be an indicator of the condition of plant communities. We developed a species dominance index (SDI) to identify dominant species and compare their behavior across multiple spatial scales. The SDI is based on three attributes (mean cover, mean species suppression, and tendency toward high cover), and it… CONTINUE READING
