A flood exceeding the 100 year average recurrence interval in November 2005 led to the failure of an upland peat bog in Waterfall Gully. The area is prone to severe bushfire and flood events and the control dam at the base of First Falls was filled with sediment sourced from Wilson Bog. A resistant quartzite bar at Fourth Falls has formed a natural constriction point against which burnt logs and debris have collected following previous fire events forming a natural dam resulting in sediment/peat accumulation upstream. The failure of the bog was inevitable as the vegetative material in the log-jam …
Relative Importance Of Fuel Management, Ignition Management And Weather For Area Burned: Evidence From Five Landscape-Fire-Succession Models, Geoffrey J. Cary, Mike D. Flannigan, Robert E. Keane, Ross A. Bradstock, Ian D. Davies, James M. Lenihan, Chao Li, Kimberley A. Logan, Russell A. Parsons

The behaviour of five landscape fire models (CAFE, FIRESCAPE, LAMOS(HS), LANDSUM and SEM-LAND) was compared in a standardised modelling experiment. The importance of fuel management approach, fuel management effort, ignition management effort and weather in determining variation in area burned and number of edge pixels burned (a measure of potential impact on assets adjacent to fire-prone landscapes) was quantified for a standardised modelling landscape. Importance was measured as the proportion of variation in area or edge pixels burned explained by each factor and all interactions among them. Weather and ignition management were consistently more important for explaining variation in area …

The probability of large-fire (>= 1000 ha) ignition days, in the Sydney region, was examined using historical records. Relative influences of the ambient and drought components of the Forest Fire Danger Index (FFDI) on large fire ignition probability were explored using Bayesian logistic regression. The preferred models for two areas (Blue Mountains and Central Coast) were composed of the sum of FFDI (Drought Factor, DF = 1) (ambient component) and DF as predictors. Both drought and ambient weather positively affected the chance of large fire ignitions, with large fires more probable on the Central Coast than in the Blue …

A great deal is already known about fire ecology in Australia, because careful observation of fire effects have been informing fire management for many thousands of years and scientific study of fire ecology has been going on for over a century, especially in the fields of forestry, evolutionary ecology, and land management. In this paper, I review some of the key questions of fire ecology identified in The Ecology of Fire (1995) for which I perceive there is a need for an expanded research effort and for better communication to politicians, policy makers, land managers, and the public at large. …

Individuals working in hot environments experience an increase in body core temperature due to the combined influences of physical activity, which elevates metabolic heat production, and external heat sources, which impede heat loss. Since dry heat exchanges are dependent upon thermal gradients, then hotter environments restrict heat dissipation, particularly when the air temperature approaches and exceeds that of the skin. Heat loss will now become progressively more reliant upon the evaporation of sweat, which is also gradient dependent.
