      On The Ground • Ecological Site Descriptions (ESDs) and underlying state-and-transition models are part of a move toward a more dynamic platform of range management, but this movement is happening without evaluation of weaknesses or logical pitfalls in the ESD database. • We conducted a national-scale evaluation of the ESD database and in this paper summarize the results with particular attention on the implementation of the state-and-transition model concept within the ESD database. • We discuss the weaknesses and logical holes we identified and provide recommendations that can be used to organize efforts to improve, adapt, or discard certain elements of ESD state-and-transition Models.
    • The Common Range and Forage Types of the Islands of Hawaii

      May, Joseph A. (Society for Range Management, 2014-08-01)
      On the Ground • The major range and forage types on the islands of Hawaii are principally naturalized plant communities with a steady-state disclimax, though there are more seldom-occurring naturalized and even less-often–occurring native historic types present. • In this article, I describe the characteristics of the six major range types using traditional Clements– Dyksterhuis range models for simplicity. My goal is to assist conservationists or professional agriculturists in making decisions on ranches and public lands of Hawaii.
