Resumen:
Misodendrum (M) is endemic of subantartic forests while Usnea (U) is widely distributed. Both are characteristic of Nothofagus forests in Patagonia, where harvesting could affect those populations. The aim was monthly quantify biomass fall of U and M during 2-3 years in primary-P, secondary-J and managed forests (dispersed-D and aggregated-A retention, and silvopastoral-S) of N. pumilio (lenga) and N. antarctica (ñire) forests. Ten biomass traps were placed in 21 stands and data was analyzed with ANOVAs. In lenga forests, U and M biomass varied among treatments (F=14.9 p
