Following harvesting operations within the Quebec mixedwood region, decadence symptoms are frequently observed on residual paper birch trees, compromising future harvests. Simultaneously, these residual stands are often a constraint to the establishment and growth of valuable regeneration. In the context of intensive forest management and preservation of the conifer component in mixedwood stands, it is important to identify factors associated with paper birch post-logging decadence. Ninety-eight (98) stands were sampled along a partial cutting chronosequence of 1 to 11 years old in order to ex

Abstract Seven northern hardwood stands were evaluated for damage after mechanized harvesting. Four different harvesting systems were evaluated: harvester and grapple skidder, processor and forwarder, chainsaw and cable skidder, and chainsaw and forwarder. There was not an excessive amount of damage occurring to any of the residual stands, and there was an adequate number of residual trees per acre in all diameter classes to meet residual stand structure goals. The majority of the damage that did occur was to the bole portion of the tree and to the 2–8-in. dbh size classes. There was no strong

Burned areas and patches of residual live trees were mapped from post-fire aerial photographs of 168 mixedwood stands (a total of 9367 ha), in eight large wildfires in the boreal forest of northern Alberta. The stands were stratified into three size classes: small (<10 ha), medium (10–60 ha), and large (>60 ha).We described the area occupied by single live residual trees, unburned patches of live trees and partially burned patches of live trees within these mixedwood stands.

Abstract Diameter-limit harvesting has long been suspected as a dysgenic forestry practice, but a conclusive, practical demonstration of the effects of this selection technique on residual tree performance is lacking. To determine the effects of repeated diameter-limit harvesting on the phenotypes of residual trees, we compared radial growth patterns of residual red spruce trees (with ages greater than 100 years) after diameter-limit harvests with those of residual trees in stands subjected to positive selection harvesting. After nearly 50 years of repeated harvesting, residual trees in the di

Abstract When landowners want to develop and maintain an uneven-aged tree structure in eastern hardwood stands, single-tree selection often is suggested as the only advisable, long-term partial regeneration harvest method. Single-tree selection is preferred because it provides a means for improving quality and controlling stocking of the residual stand necessary for sustained yield of desired products. Although studies have shown that single-tree selection is feasible where desirable shade-tolerant species can be regenerated, it is rarely applied because marking stands for harvest can be diffi

Abstract In Maine and adjacent eastern Canadian provinces, cut-to-length harvesting has emerged as an ecologically attractive method of thinning conifer plantations and natural stands. Yet regional information on the extent of residual stand damage associated with this system is lacking. Eight naturally regenerated red spruce (Picea rubens) stands in northern Maine were studied; all stands were thinned in 1997–1998 with a processor and forwarder combination. Field methods consisted of examining individual trees near forwarder trails for bole damage and measuring the size and aboveground height

Green tree retention, a practice based on ecosystem science, has been integrated into forest management as a working hypothesis, requiring research and monitoring to quantify its effects.

So far, the damage caused by thinning operations in montane tropical forests is unknown.

For this, we installed 52 permanent plots of 50 m x 50 m in two force types. In the valley forest (VF), we extracted an average basal area of 2.75 m² ha–1, in the ridge forest (RF) an average basal area of 0.8 m² ha–

Abstract Wind damage to forests is a recurrent hazard in many parts of the world. High winds can uproot trees, break stems, cause malformations, and retard growth. They can also disrupt planned management, causing economic losses from higher logging costs, damage during storage, unharvested wood, lowered increment in residual stands, and shortened rotations, besides reducing landscape quality and habitats for wildlife. Forests in temperate maritime regions suffer most seriously from wind damage, but those in continental mountainous regions can be badly affected too. In some places wind may be
