avondale-bepress.abstract<p>The effect of disturbance regime (time since last fire or slashing) on the vulnerable plant species, Darwinia glaucophylla, was assessed on the Central Coast of New South Wales (NSW), Australia. The abundance, growth and flowering of D. glaucophylla adults and abundance and growth of seedlings was measured within sites that had either been recently burnt (≤ 5 years), long unburnt (≥ 14 years) or regularly slashed (30 cm above ground) along a utility easement. Our results showed that Darwinia glaucophylla was most abundant at slashed sites, followed by recently burnt sites; it was present but not abundant at unslashed sites that were burnt ≥ 14 years ago. Seedlings were only found at one, recently burnt site. Disturbance regime had no significant effect on the timing or density of flowering. We found that fruits collected from sites with different disturbance regimes did not germinate after exposure to various combinations of heat, smoke-water and/or scarification. Recently burnt sites contained plants producing a significantly greater number of viable fruits compared to those from other disturbance regimes. Fire and slashing altered the habitat of D. glaucophylla in slightly different ways. The implications of our findings for the management of the species are discussed.</p>
