Abstract Studies of gap dynamics have contributed significantly to our understanding of the role of small-scale disturbance in forest ecosystems, but have been little used by foresters for predicting tree responses to partial cutting. Fifth year growth and survival of five commonly planted tree species were contrasted in canopy gaps (single-tree to 5000 m 2 ), in the forest understory and in the open conditions of a clear-cut. There were strong and consistent trends in growth response among the… Expand
Tree recruitment in gaps of various size, clearcuts and undisturbed mixed forest of interior British Columbia, Canada
Tree seedling recruitment was monitored after various types of logging in mixed conifer and deciduous forests of northern British Columbia, Canada. Predicting tree seedling recruitment afterExpand
Many New England forests today are fragmented, or divided into unconnected groups. This fragmentation has affected the structure of forests by the inevitable creation of forest edges and gaps in theExpand
A review of the roles of forest canopy gaps
Treefall gap, canopy opening caused by the death of one or more trees, is the dominant form of disturbance in many forest systems worldwide. Gaps play an important role in forest ecology helping toExpand
Growth Response of Mature Trees versus Seedlings to Gaps Associated with Group Selection Management in the Sierra Nevada, California
Radial growth response of mature conifer trees to creation of gaps using group selection was measured along transects extending from gap edges into a surrounding forest in central Sierra Nevada,Expand
Gap-based silviculture in a sierran mixed-conifer forest: effects of gap size on early survival and 7-year seedling growth
Experimental canopy gaps ranging in size from 0.1 to 1.0 ha (0.25 to 2.5 acres) were created in a mature mixed conifer forest at Blodgett Forest Research Station, California. Following gap creation,Expand
Seedling recruitment in response to artificial gaps: predicting the ecological consequence of forest disturbance
An integrative effect of gap size and within-gap location on seedling performance of shade-intolerant oaks is shown, suggesting future studies should evaluate the influence of within- gap location in conjunction with the role of gapsize. Expand
Canopy Gap phase regeneration: A study in moist temperate forests of Central Himalayas, India
Broad leaved forests continuously have some asynchronous and localized disturbance events.Tree fall gaps are the dominant form of such disturbances in these forests. Moist temperate forests dominatedExpand
Influences of gap position, vegetation management and herbivore control on survival and growth of wh
White spruce was planted across large canopy openings to determine whether survival and height growth is influenced by position within gap and by differing levels of competing vegetation control of aspen and understory plants, which has implications for the timing and intensity of silvicultural treatments for harvesting and planting.

Stand dynamics of mixed-Nothofagus forest
Sustainable management of mixed-species forests for timber is underpinned by research on forest stand dynamics and quantification of tree recruitment, growth and mortality rates. DifferentExpand
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. Expand


Forest development in canopy gaps in old-growth beech (Nothofagus) forests, New Zealand
Tree size and age structures, treefall and canopy gap characteristics, and regeneration responses to treefalls were compared for three stands of old-growth beech (Notho- fagus) forest dominated by N.Expand
Regeneration from seed of six tree species in the interior cedar-hemlock forests of British Columbia as affected by substrate and canopy gap position
To predict regeneration success in these forests, for either silvicultural purposes or to permit a better understanding of community dynamics and succession, it is important to consider the influence of position inside and outside of gaps and the nature of the seedbed substrate. Expand
Gap Partitioning Among Maples (Acer) in Central New England: Survival and Growth
Striped maple appears to be a superior generalist, red maple is a weaker generalists, and sugar maple shows the poorest performance in a manner that is nearly insensitive to the gap-understory gradient in the authors' experimental system. Expand
Canopy gaps in Douglas-fir forests of the Cascade Mountains
The gap survey found a higher proportion of gaps in the mature stand than in the old-growth stand, and the ratio of seedling density in gaps to density under canopies was about 3 for the matureStand and about 9 for the ol... Expand
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.

Gap size, within-gap position, and canopy structure effects on conifer seedling establishment
1 Emergence, establishment and growth of Abies amabilis, Pseudotsuga menziesii and Tsuga heterophylla were studied for 2 years in variously sized canopy gaps created in four stands on the west slopeExpand
Gap-phase structure of a subalpine old-growth forest
Four stands in a subalpine old-growth forest in the Coast Mountains of southwestern British Columbia are examined for gap-phase structure and dynamics, finding the high proportion of area in gap and dynamics in this forest are distinctive. Expand
Natural Disturbance and Gap‐Phase Regeneration in a Wind‐Exposed Tropical Cloud Forest
Experimental investigation of colonization of exposed soil in treefall gaps indicated that buried seeds give rise to many more tree seedlings than seeds dispersed into recent gaps, and many of the saplings in gaps started life as epiphytic seedlings in the crowns of the trees that fell. Expand
Growth of planted tree seedlings in response to ambient light levels in northwestern interior cedar-hemlock forests of British Columbia
Five years after planting, total size and recent growth rates varied little among species from low to high light, implying an absence of trade-offs in low- and high- light growth strategies. Expand

Tree size and age structure, tree-fall and gap char- acteristics, and regeneration in gaps were studied in Nothofagus-dominated old-growth forests in Tierra del Fuego, Argentina. Gap-phaseExpand
