Interactive comment on “Time since death and decay rate constants of Norway spruce and European larch deadwood in subalpine forests determined using dendrochronology and radiocarbon dating” by M. Petrillo et al

چکیده
The decay rate of standing deadwood, i.e., of snags, is slower than that of downed deadwood in contact with the forest floor. We agree with Dr. Anger’s opinion that this may be an important reason why clear age differences in the decay classes 1 – 3 are missing. Some snags fall earlier others later. This overshadows a clear age trend in decay. If the rate at which snags of larch fall down on the floor was lower compared to that of spruce then this also would be a cause for the differences in decay rates between these two types of trees. Unfortunately, the fall rates of snags of the C9144

Time since death and decay rate constants of Norway spruce and European larch deadwood in subalpine forests determined using dendrochronology and radiocarbon dating
Due to the large size (e.g. sections of tree trunks) and highly heterogeneous spatial distribution of deadwood, the timescales involved in the coarse woody debris (CWD) decay of Picea abies (L.) Karst. and Larix decidua Mill. in Alpine forests are largely unknown. We investigated the CWD decay dynamics in an Alpine valley in Italy using the chronosequence approach and the five-decay class syste...

their discussion, the authors refer to studies that showed that the decay rate of standing dead wood is slower than dead wood in contact with the forest floor. This contributes to explain the absence of clear differences in properties in classes 1-3. The same argument might potentially be used to explain the differences in decay rates of larch and spruce. Assessing the time elapsed standing of ...
