ABSTRACT Although fire management is essential to conserve ecosystems and protect communities in Australia, the best way to achieve these goals is controversial. Recent advances that use satellite imagery to map fire severity focus on canopy effects and provide limited ecological information. Fires and prescribed burns can also occur over weeks to months, limiting the relevance of a single post-fire

ABSTRACT Although studies in mainland states of Australia and overseas show that the conversion of native forests to plantations can reduce carbon (C) stocks in soils, no studies have been undertaken in Tasmania to assess how plantations affect soil C stocks. To address this knowledge gap, we compared soil C concentrations and C stocks to 30 cm depth in native ‘mixed’ eucalypt forests and adjacent

No evidence that timber harvesting increased the scale or severity of the 2019/20 bushfires in south-eastern Australia Aust. For. (IF 2.1) Pub Date : 2021-07-27 R. J. Keenan, P. Kanowski, P. J. Baker, C. Brack, T. Bartlett, K. Tolhurst
ABSTRACT In the summer of 2019/20, bushfires of unprecedented scale in south-eastern Australia focused attention on how forest management might have affected their risks and impacts. Some argued that the severity and extent of these fires were made worse by timber harvesting and associated forest management and that harvesting in native forests should cease as a means for reducing fire risk. Little
