Tree and log diameters are usually measured outside bark, but inside-bark diameters are of greater economic interest and are often derived with local or regional bark thickness equations. To date, the influence of measurement method, sampling design, and sample size on bark thickness equation accuracy and precision has received limited attention. The objectives of this study were to use an exte...

Measurements of bark thickness generally ignore the fact that bark is comprised of both living inner bark (phloem) and essentially dead outer bark (rhytidome). Discerning between them has ramifications for the utility of bark as a byproduct of timber harvesting and its functionality on a living tree. Inner bark and outer bark thicknesses for longleaf pine (Pinus palustris Mill.) were investigat...

1. Bark is a vital and very visible part of woody plants, yet only recently has bark characteristics started to be considered as key traits structuring communities and biomes. Bark thickness is very variable among woody plants, and I hypothesize that fire is a key factor selecting for a thick bark, and thus, at the global scale, a significant proportion of the variability in bark thickness is e...

the non-destructive meyer method was evaluated to determine the bark volume of beech (fagus orientalis lipsky) stands in north of iran. the sample size was 185 standing trees collected from 4 geographical aspects (north, south, west and east) aspects. the constant k values and bark thickness (2e mm) of 185 standing trees were used to calculate the bark volume by the meyer method. in this study,...

Bark is the outermost covering of stems in woody plants and plays a fundamental protective role. Recently I hypothesized that ‘at the global scale, a significant proportion of the variability in bark thickness is explained by the variability in fire regimes’, and specifically predicted that frequent low intensity fires select for thick bark (Pausas, 2015). In addition, I suggested that differen...

Forest ecosystems where periodical tree bark harvesting is a major economic activity may be particularly vulnerable to disturbances such as fire, since debarking usually reduces tree vigour and protection against external agents. In this paper we asked how cork oak Quercus suber trees respond after wildfires and, in particular, how bark harvesting affects post-fire tree survival and resprouting...

Relationships between the flammability properties of a given plant and its chances of survival after a fire still remain unknown. We hypothesize that the bark flammability of a tree reduces the potential for tree survival following surface fires, and that if tree resistance to fire is provided by a thick insulating bark, the latter must be few flammable. We test, on subalpine tree species, the ...

Abstract Bark characteristics are not only used in the forest-wood supply chain, for example to calculate standing volumes, but also transform wood volumes and masses. In this study, bark thickness, volume mass were analyzed on basis of 150 Scots pine discs, with a mean diameter 13 cm. The double thickness was 3.02 mm, proportion 5.6% 3.3%. proportions significantly affected by log-specific var...
