Australia commonly experiences extensive wildfires, mostly during its hot dry summers. These often lead to a significant loss of life and property. The October 2013 Blue Mountains Fire burnt through more than 100,000 hectares and generated a large amount of fire dust that was…

Influence of fire on critically endangered Swartland Shale Renosterveld in the Cape Floristic Region
Questions: The degree to which renosterveld shrublands are fire-dependent is currently unclear. To address this issue, the following questions were asked: (1) does smoke stimulate germination of soil-stored seeds in renosterveld; (2) does recently-burned renosterveld display…

Warming in the boreal forest region has already led to changes in the fire regime. This may result in increasing fire frequency or severity in peatlands, which could cause these ecosystems to shift from a net sink carbon (C) to a net source of C to the atmosphere. Similar to C…
