To further understand the mechanics of trees under dynamic loads, we recorded damped oscillations a Douglas fir (Pseudotsuga menziesii) tree and its stem without branches. Eigenfrequencies branches were calculated compared to oscillation frequency intact tree. The term eigenfrequency is used here characterize resonance branch fixed at proximal end solid support. All large had nearly same as This property prerequisite for distribution mechanical energy between leads an enhanced efficiency damping. We propose that constitute systems coupled oscillators tuned allow optimal dissipation.
