Summary In north-eastern New South Wales (NSW) the Regional Forest Agreement process has transferred more than 400 000 ha of state forests to national park, and restricted silviculture to ‘single tree selection’ and a light form of ‘Australian group selection’. While these silvicultural systems are theoretically well suited to ecologically sustainable forest management, there is concern that in their current form they are not achieving adequate regeneration or optimising the growth of that… 
Variable-retention harvesting in Tasmania: regeneration success?
Summary Society’s changing expectations for forest management and an improved understanding of wet-forest ecology have led to the adoption of variable-retention silviculture in Tasmania’s old-growth

Seedfall and seed viability within artificial canopy gaps in a western Washington douglas-fir forest
Seedfall of coast Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii) has been studied at the forest edgeclearcut interface and in small canopy gaps, but it has not been evaluated in
Effects of gap size, gap age, and bamboo Fargesia denudata on Abies faxoniana recruitment in South-western China
To study the effects of gap size, gap age and bamboo Fargesia denudata on natural regeneration of Abies faxoniana, both of which are the ubiquitous dominants in this research area, the number of bamboos in subalpine coniferous forests in Wanglang Natural Reserve in Southwestern China was randomly established.
Comparative performances of new and existing indices of crown asymmetry: an evaluation using tall trees of Eucalyptus pilularis (Smith)
Over the past 50 years, crown asymmetry of forest trees has been evaluated through several indices constructed from the perspective of projected crown shape or displacement but often on an ad hoc


Review of the impact of retained overwood trees on stand productivity
Following harvesting, retained eucalypt stems will exert a suppressive influence on regrowth in terms of stocking, and height and volume growth, which has been the subject of several studies in Australia.
Gap dynamics of forest trees: A review with particular attention to boreal forests
Research in the Scandinavian and Russian boreal forest, as well as in high-altitude boreal "outliers" found in Japan and the United States, is showing that gap disturbance determines forest structure and processes to a greater extent than previously assumed.
Gap Partitioning among Tropical Rainforest Trees
This paper summarizes data on regeneration patterns of trees within the framework of hypotheses that (1) tree species partition gaps of different spatial distributions and sizes and (2) partitioning occurs because regeneration strategies keyed to gaps of particular size ranges involve adaptive compromises that restrict the competitive success of the species in gaps of differing sizes.
Current forms and extent of retention areas within a selectively logged blackbutt forest in NSW: a case study
Summary This case study estimates the cost (in terms of reduced royalty) of the current commitment to protecting non-wood values by retaining ecologically sensitive areas in a selectively logged
Effect of overwood trees on growth of young stands of Eucalyptus sieberi
Summary The suppressive effect of overwood trees on regrowth was studied by establishing transects from isolated overwood trees into established 20 to 30 year-old regrowth. Plots three metres in
Establishment, suppression and growth of Eucalyptus delegatensis R.T. Baker in multiaged forests .II. Sapling growth and its environmental correlates
Density, height, diameter and wet weight of E. delegatensis regrowth are highly positively correlated with the distance to the nearest tree but are only related to solar radiation in the gaps, while sapling growth outside the influence of adult trees increases with increasing incident solar radiation.
Gap Light Regimes Influence Canopy Tree Diversity
How changes in latitude influence gap light regimes and, hence, replacement patterns of canopy trees in temperate and tropical forests is discussed.
