“…This could be explained by constant growth rate of rot regardless of tree size (Etheridge, 1961). However, Witt (2010) found positive relationship for tree DBH and both incidence and volume of infection. Alternatively, higher infestation of smaller trees by the poplar borer can be explained by its preference of young and small dimension trees (Nuorteva et al, 1981;Brandt et al, 2003).…”

Zeps, M., Senhofa, S., Zadina, M., Neimane, U., Jansons, A. 2017. Stem damages caused by heart rot and large poplar borer on hybrid and European aspen. -Forestry Studies | Metsanduslikud Uurimused 66, 21-26. ISSN 1406-9954. Journal homepage: http://mi.emu.ee/forestry.studies Abstract. Solid wood production of hybrid aspen requires relative longer rotation periods, thus increasing risk of wood damages by pests and diseases. We compared damages by heart rot and poplar borer of 48 years old hybrid (Populus tremuloides Michx. × P. tremula L.) and European aspen in a progeny trial located in Eastern part of Latvia. Trees were harvested and rot patches and galleries were recorded and measured at a stump level. The number of galleries had positive relation on number of patches and total area of rot. The susceptibility of the rot and poplar borer was similar for both hybrid and European aspen. Yet, some differences among families were detected. No effect of pathogens damage was observed on the tree growth. Larger trees had smaller proportion and incidence of rot and galleries per unit of area as well as wider outer rot-free wood layer.

“…It explains the observed distribution of galleries in sapwood. Incidence of rot increases with the age of the tree (Witt, 2010) hence, at the age of 48 years rot was detected on > 99% of trees, regardless of their vigour.…”

“…The role and importance of heart rot in hardwood species in the formation of nest cavities, as well as the role of snags in an ecosystem, are well documented (Thomas et al 1979;Witt 2010). Barred Owl nest cavities found in this study were natural and had resulted from damage to and decay of the tree.…”

“…Barred Owl nest sites were located using nocturnal audio surveying and diurnal audio playback with passive observation during the breeding season (February -June in 2009 and2010) Whiklo 2011). Survey transects were laid out in areas based on Barred Owl detection data obtained from the Manitoba Nocturnal Owl Survey (JRd, unpublished data;op.…”

“…Fungal rot is prevalent in older and/or larger stands of trees (Witt 2010) and has positive effects for both primary and secondary cavity nesters (Bunnell et al 2002). higher levels of moisture and humidity, factors found at sites within close proximity to water, increase the rate of decay in trees (Jackson and Jackson 2004).…”

Whiklo, Todd M., and James R. duncan. 2014. Characteristics of Barred Owl (Strix varia) nest sites in Manitoba, Canada.Canadian Field-Naturalist 128(1): 38-43.during 2009 and 2010, nine Barred Owl (Strix varia) nest sites were located in Manitoba, Canada, and data on nest trees, nest structure, and nest site habitat were collected. Nests were located in a variety of tree species, including Balsam Poplar (Populus balsamifera), Paper Birch (Betula papyrifera), Trembling aspen (Populus tremuloides) and Burr Oak (Quercus macrocarpa). all nests were in tree cavities, and the majority of nests were in dead trees (67%) and had lateral openings (67%). habitat surrounding nest trees and estimated canopy cover were highly variable. diameter at breast height of nest trees, cavity width, and cavity depth were consistent and were determined to be the most reliable indicators of nest suitability for breeding Barred Owls. We conclude that the distribution of nesting Barred Owls is influenced more by availability of suitable nest sites than by nest tree species or nest site habitat.
