“…Listed in order of decreasing abundance. Gaylussacia baccata: a rhizomatous shrub Gaylussacia baccata persists in the shrub layer, developing a dense cover under occasional gaps in the tree canopy (Stephenson 1965;Reiner 1967). Following cool, ground-level fires it sprouts vigorously (Cantlon & Buell 1952;Matlack & Good 1987) which may also lead to dense local stands.…”

“…Other rhizomatous shrubs show variations on this strategy: Vaccinium vacillans was similarly clustered but has been shown to be more successful in deeper shade (Stephenson 1965;Reiner 1967) and to recover from burning more quickly (Cantlon & Buell 1952). At a scale of stands, densities of both Gaylussacia baccata and Lyonia mariana were also significantly correlated with soil water capacity (Table 1), a trend which extends to separate upland and lowland shrub communities (Roman et al 1985).…”

Herb and shrub layer vegetation was surveyed in the oak-pine upland forest of the Pine Barrens region of New Jersey (USA). To describe spatial distributions of individual species, 15 4 m 2 quadrats were censused in each of 34 stands. At the scale of whole stands, stem densities were significantly related to several forms of historical disturbance including canopy defoliation and f'we. At the scales of 1 m 2 and 4 m 2 quadrats, distributions of the 19 most abundant species were all aggregated to some degree, with clonal species more strongly clustered than non-clonal. Shrub stems tended to be strongly clustered, and to be distributed independently of leaf litter. By contrast, tree seedlings were only marginally clustered, and were significantly more common in quadrats with a lower litter cover. Clonal herbs exceeded shrubs in degree of aggregation, but were also sensitive to the local accumulation of leaf litter. Distributions of non-clonal herbs were sensitive to leaf litter, but were only marginally clustered, and appeared to depend upon gaps in the tree canopy. Rather than supporting a single life history, a combination of disturbance types has allowed a variety of species with different ecological requirements and growth forms to coexist in the same site. Overall species diversity can be maintained in this ecosystem without invoking community-level interactions.

“…Periodic inventories of individuals in permanent plots represent another method of analyzing change (Leak 1970, Stephens and Waggoner 1970, Peet and Christensen 1980. Due to the limited availability of a long-term data base, however, most of the existing analyses have focused on patterns of change generally within a 10-20 yr range (Stephenson 1965, Schmelz et al 197 5, Abrell and Jackson 1977, Christensen 1977.…”

Fifty Years of Change in the Arboreal Vegetation of Heart's Content, An Old‐Growth Hemlock‐White Pine‐Northern Hardwood Stand

The structure and composition of Heart's Content, an old—growth hemlock—white pine—northern hardwood stand in northwestern Pennsylvania, were studied in 1929. The original plots, established by H. J. Lutz, were relocated and remeasured in 1978. Heavy deer browsing over the past 40 yr has dramatically altered the diameter size—class distribution of the stand, creating a gap in the smaller size—classes of some species. The rapidly growing, shade—intolerant species have the largest gap, while the slower growing, more tolerant species are still represented in the smaller size—classes.
