Members may find this guide useful and/or interesting.

It is a manual for identifying old growth trees and forests in western Washington, and for understanding stand dynamics (how a forest changes over time). It discusses visual indicators of age and other concepts we can apply to designing our trees.

The info is specific to most of the major conifers species here but can be applied in a broader sense to genuses used in bonsai (Picea—spruce, Tsuga—hemlock, Pseudotsuga—Douglas-fir, Abies—fir, and Thuja—“cedar”).

A manual for eastern Washington also exists. It covers similar topics for trees in more arid parts of the state, like larches and pines.

Thanks for posting . I found it very interesting info . I have studied similar info on forests . Here in Ontario Canada . But there is less dynamics here . Without the ocean driven weather patterns and less elevation change . Here it’s more . Just about precipitation in that area . And the age of the forest . As climax trees in each area take over . In the lifespan of a Forest . Then fire normally starts the cycle over . So there is less difference . In that small a area . . We have different forests . But each covers for more area
