The Stability of a Selectively Logged Forest and the Instability of the same Mutilated Forest.
 
The forest in the background has been selectively logged over the last 140 years and fulfills the functions of relative stability of a diversity of species and ages, hydrology, micro-climate, resource, carbon sequestration, nutrient levels and habitat.

---

With responsible management it could continue to be selectively logged forever while still  maintaining all the vital functions of mixed native forests.

By comparison the foreground is unconscionable total destruction creating long term if not permanent instability of everything.
