Etsuko Nonaka and Thomas A. Spies. 2005. Historical range of variability in landscape structure: a simulation study in Oregon, USA. Ecological Applications 15:1727–1746.

Appendix A (Table A1). The mean, minimum, and maximum of the metrics from the simulated historical landscapes that fell in the 90% HRV likelihood of the age classes, and values of the metrics measured on the current and potential future landscapes under CPS of the Oregon Coast Range, Oregon, USA.  The time steps for the future landscapes are 50 and 100 year after the initiation of the simulation.
