Abstract

Seedling and sapling regrowth occupies gaps and includes part of the understorey in the multiaged Eucalyptus delegatensis dry forests of central Tasmania. This regrowth is even-aged for any particular area. Variation in sapling height is symmetrical across east to west sections of gaps, 20-50 m diam., but asymmetrical in the north to south sections, where the tallest seedlings are found to the south. 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. Concentrations of most major plant nutrients in the surface soil, and soil moisture-holding capacity, have no strong relationship with the various growth measures. Thus, adult trees suppress sapling growth independent of incident solar radiation, while sapling growth outside the influence of adult trees increases with increasing incident solar radiation.
