Table 1. The estimated mean volume (with standard error) of dead wood (m3/hectare), the total and mean number (with standard error) of dead wood items in the study plots, and the number of plots particular dead wood type was encountered. Values are given separately for the two size classes (2–9 cm and ≥10 cm).
