Abstract: Epiphytes are sampled concurrently with measurements of surface area of trunk and branch systems ofold-growth Douglas-fir (Pseudotsuga menziesii). Crude predictions of epiphyte biomass in branch systems arecorrected by more detailed sampling of a subset of branch systems. Nitrogen analyses enable conversion ofepiphyte biomass to the total amount of nitrogen present in the epiphytes.
