Effect of overwood trees on growth of young stands of Eucalyptus sieberi

Small mammals and retention islands: An experimental study of animal response to alternative logging practices

“…For example, they are foregone revenue for landowners, may inhibit the growth of newly established trees, and present safety issues for timber workers (Incoll, 1979;Bunnell and Dunsworth, 2009). In addition, there are risks of retained islands being badly damaged by regeneration burning on steep terrain.…”

What strategies are effective for perpetuating structures provided by old trees in harvested forests? A case study on trees with hollows in south-eastern Australia

“…There can be economic costs associated with both strategies (Kohm and Franklin, 1997). Further, if more living trees must be retained on logged sites then there can be an economic cost associated with a reduced rate of growth among trees growing in close proximity to these trees (Incoll, 1979). Old trees can also harbor pathogens that can affect the regenerating stand (Castello et al, 1995).…”

Stand characteristics, understorey associates and environmental correlates ofEucalyptus tetrodonta F. Muell. forests on Gunn Point, northern Australia

“…3). The suppressive effect of eucalypt overwood has been documented by Henry & Florence (1966), Opie (1968), Gill & Ashton (1971), Incoll (1979), Rotheram (1983), and Bowman & Kirkpatrick (1985b) and in the case of E. delegatensis" R.T. Baker was shown to be related to moisture competition (Bowman & Kirkpatrick, 1985c). Similarly, the pattern of seedling and advance growth size classes was also significantly clumped in all quadrats other than the 27 × 27 m quadrat from the structural group C (Fig.…”

“…The seedlings form a pool of fire resistant lignotuberous stunted saplings or 'advance growth'. The recruitment of these plants into the stand requires the formation of a gap that frees the saplings from the suppressive influence of the overwood (Zimmer, 1940;van Noort, 1960;Henry & Florence, 1966;Parsons, 1968;Curtin & King, 1979;Incoll, 1979;Rotheram, 1983;Bowman & Kirkpatrick, 1985b). Such gaps occur in nature following the repeated basal attrition by fire that results in stem failure (Bowman & Kirkpatrick, 1985a).…”
