Short summary

The timescales involved in the decay of coarse woody debris (CWD) and related chemical components of spruce and larch in Alpine forests are largely unknown. Dendrochronology and ¹⁴C dating were used to assess time and rates. Distinct differences between tree species occur only at an advanced stage of decay. Larch CWD reaches an age of 210 years and spruce 77 years. Using this approach, the half-lives of cellulose (21 yr for spruce and 50 yr for larch) and lignin (> 100 yr) could be determined.
