Reduction in basal area increment ofEucalyptus obliquafollowing crown scorch

Identification of the fungi associated with damping‐off in the regeneration of Eucalyptus obliqua and E. radiata in a central Victorian forest

“…Seed treatment with fungicides can have a marked phytotoxic affect on germination, offsetting any impact on fungal populations (NEUMANN et al 1978). Neither of these options are applicable in the Wombat Forest as intense fires in partially cut stands may result in significant crown scorch which affects basal area increment of residual trees (KELLAS et al 1984), and the current system relies on natural seedfall.…”

Evaluating long-term effects of prescribed fire regimes on carbon stocks in a temperate eucalypt forest

“…For example, the degree and duration of changes in soil carbon stocks will vary with fire severity, but also with post-fire interactions between climate and topography, which influence erosional losses and plant inputs to soil through regeneration and growth (Certini, 2005). Similarly, fire effects on tree growth will depend on the immediate damage to roots, stems and crown (Kellas et al, 1984;Murphy et al, 2010), and on the post-fire growth environment including climate and stand structure (Hurteau and North, 2009;Bennett et al, 2013). Teasing apart these various influences to identify the most important variables for explaining fire effects on forest carbon stocks, will not only improve mechanistic understanding but will also help with identifying fire management options; that is, can carbon stock changes associated with prescribed fire be consistently linked to particular variables, and do these insights offer opportunities to actively manage the carbon 'outlays' (Bradstock et al, 2012) of prescribed fire regimes?…”

Simulation of bracken cover in forested areas in Victoria in response to season, overstorey and fire conditions

“…It is also assumed that, when the tree canopy is scorched, all the leaves drop and the branches and twigs remain, so that the cover of the scorched canopy is reduced by half. It is also assumed that the canopy returns to near pre-fire conditions after 4 years (Kellas et al 1984) according to a logistic function (equation 3). In addition, on the basis of Attiwill's (1979) work, it is assumed that it takes 10-15 years for tree and tall shrub crowns to fully occupy a site after logging; a time of 10 years is used in this model (equation 4).…”
