Abstract:
... Woody‐plant encroachment represents a global threat to grasslands. Although the causes and consequences of this regime shift have received substantial attention, the processes that constrain reassembly of the grassland state remain poorly understood. We experimentally tested two potentially important controls on reassembly, the past influence of trees and the effects of fire, in conifer‐invaded gr ...

Abstract:
... Wildland fire dynamics are a complex three-dimensional turbulent process. Cellular automata (CA) is an efficient tool to predict fire dynamics, but the main parameters of the method are challenging to estimate. To overcome this challenge, we compute statistical distributions of the key parameters of a CA model using infrared images from controlled burns. Moreover, we apply this analysis to differe ...

Abstract:
... Multiple studies have examined ‘what’ people think about fuel management (perceptions); fewer have examined ‘how’ people think about it (structure of thoughts). In an Australian study, we used Integrative Complexity Theory (ICT) to explore the relationship between how complexly people thought about, and how acceptable they found, three fuel management strategies: prescribed burning, mechanical thi ...

Abstract:
... The negative biodiversity effects of timber- and biofuel-oriented forestry practices can be alleviated by leaving retention trees and logging residues following clear-cut harvests and occasionally including prescribed burns. Such measures can potentially maintain substrates especially for dead-wood-associated species during young, post-harvest successional stages. However, the availability and tem ...

Abstract:
... Charred micro-remains in archaeological sediments vary from large destruction layers, to localized lenses, and they are invaluable stratigraphic anchors when found in situ. Visual observations of black sediments are a good marker for primary depositions of burning events, however, an independent criteria is necessary to verify these sediments were not mixed with other contexts. In this study, a mi ...

As a result, dates reported as YBP should be reported as BC.

Abstract:
... Prescribed (or “planned”) burning is used by land managers to reduce fuel-loads in order to mitigate the spread of wildfire, thereby protecting life and property, and to promote environmental heterogeneity to enhance biodiversity. Globally, many fire management agencies focus on increasing extent and frequency of prescribed burning. There is a need to assess how high levels of prescribed burning m ...

We found greater abundance of fire‐sensitive species in the seed rain, likely contributing to woody encroachment. Flexible fire management policies that allow for natural and prescribed fires may be req ...
