“…The author estimated probability of butt rot incidence of about 30% in 120-year-old and 60% in 200-year-old stands. Similar relationships were observed in managed silver fir stands examined during preliminary studies with regard to stand age and butt rot infection carried out in the Forest District Ujsoły (Niemtur et al 2013).…”

“…In comparison to Norway spruce, there has been reported lesser vulnerability of silver fir to wood decay (Kohnle, Kändler 2007). Quite the opposite, the results of the study carried out with the use of sonic tomography in managed forests of the Żywiec and Silesian Beskid indicated that butt rot problem concerned spruce and fir trees to a similar degree (Niemtur et al 2013).…”

The aim of the study was to analyse butt rot incidences in silver fir stands of selected nature reserves and national parks. The study included 11 stands in Carpathian forests and for comparison 4 stands outside the Carpathians. To identify butt rot in fir trees, we used the non-invasive method of acoustic tomography. We tested 30 randomly selected fir trees in each of the 15 stands using Picus Sonic tomography to determine butt rot occurrence and to assess the proportion (%) of healthy wood in cross-sections of the tree trunk. The results indicate significant differences in the frequency of butt rot in silver fir at the individual level as well as the population level. This variability in frequency was not dependent on geographical location of the investigated stands.

“…Wood deterioration was closely related to the biometric variables (Table 4 and Figure 5), and the positive association showed that older and larger trees were more susceptible to stem rot. In previous studies with other tree species, wood decomposition was found to increase proportionally with age [2,[75][76][77]. The incidence in C. cateniformis was directly related to age [2,45,75], and over-mature trees were found to have a high percentage of medullary rot [2,75].…”

Forest plantations can be established in order to restore degraded areas. Acoustic tomography, which is of increasing importance in forest management, was used in the present study to obtain information for managing plantations of Cedrelinga cateniformis Ducke in the Peruvian Amazon. The species is valuable in the timber sector of Peru, but the core wood tends to deteriorate and develop cavities. The main objective of the study was to model wood deterioration in Cedrelinga cateniformis Ducke using the data obtained through acoustic tomography. Eight plantations of varying ages were analyzed using acoustic tomography in order to obtain indicators of wood deterioration. Biometric, climatic, and edaphic data (explanatory variables) were also measured in each plantation. The indicator variables and explanatory variables were compared and evaluated using correlation and principal component analysis. Wood deterioration was modelled using stepwise regression. The indicator variables differed significantly between plantations and were mainly correlated with the biometric variables (age and diameter at breast height). The models explained 81% of the variability of pith rot. The percentage rotten area was minimal in young plantations (1%), and the opposite was observed in mature trees (21.5 to 25.6%). The study findings provide valuable information, enabling foresters to determine the optimal age and diameter for felling Cedrelinga cateniformis in plantations in the Peruvian Amazon.
