Bark- and wood-boring beetles on Scots pine logging residues from final felling: Effects of felling date, deposition location and diameter of logging residues [PDF]

open access: yesAnnals of Forest Research, 2015
To reduce the risk of bark- and wood-boring beetle pests, the extensive removal of logging residues is conducted in forests; however, this practice can lead to a loss of saproxylic insect diversity.

Quantitative Estimation of Logging Residues by Line-Intersect Method [PDF]

open access: yesCroatian Journal of Forest Engineering, 2017
Line intersect sampling (LIS) is a method used for quantifying forest residues after logging operations. In conventional LIS theory, forest residues are considered as separate pieces of cylindrical shape, they occur horizontally, and are randomly ...

Residual log-periodogram inference for long-run relationships [PDF]

open access: yesJournal of Econometrics, 2006
We assume that some consistent estimator of an equilibrium relation between non-stationary fractionally integrated series is used in a first step to compute residuals (or differences thereof). We propose to apply the semiparametric log-periodogram regression to the (differenced) residuals in order to estimate and test the degree of persistence of the ...

Assessment of load and quality of logging residues from clear-felling areas in Järvselja: a case study from Southeast Estonia

open access: yesCentral European Forestry Journal, 2020
The properties of biomass-based fuel and combustion tests showed that logging residues are promising renewable energy sources. The data used in this study were collected from four clear-felling areas in Järvselja Training and Experimental Forest Centre ...

Simulation Studies on Line Intersect Sampling of Residues Left After Cut-to-Length Logging

open access: yesCroatian Journal of Forest Engineering, 2020
Upon carrying out logging, residues remain in the cutting area. Logging residues are an additional source of wood raw material for the production of fuel chips to be used in bioenergetics.

Predicting Logging Residue Volumes in Alaska

open access: yesForest Science, 2021
AbstractAlaska forest managers seek information on how timber harvesting practices change the creation of postharvest woody residues. To predict residue volumes, researchers investigated how residue ratios—growing-stock residue volume per mill-delivered volume—related to readily available data on logging site and tree attributes in Alaska.

Effects of post-fire logging on forest surface air temperatures in the Siskiyou Mountains, Oregon, USA [PDF]

open access: yes, 2010
Following stand-replacing wildfire, post-fire (salvage) logging of fire-killed trees is a widely implemented management practice in many forest types. A common hypothesis is that removal of fire-killed trees increases surface temperatures due to loss of ...

Regional GIS-based evaluation of the potential and supply costs of forest biomass in Sweden [PDF]

open access: yesFrontiers of Agricultural Science and Engineering, 2017
The potential for harvestable forest fuel (logging residues and stumps from regeneration fellings and small diameter trees from early thinnings) in Sweden, divided in five regions, is provided.
