Journal ArticleDOI
Evaluating techniques for mapping island vegetation from unmanned aerial vehicle (UAV) images: Pixel classification, visual interpretation and machine learning approaches
Sarah Hamylton,Rowena H Morris,Rowena H Morris,Rafael Cabral Carvalho,Rafael Cabral Carvalho,N Roder,P Barlow,K Mills,Lei Wang +8 more
TL;DR: The CNN approach emerged as a promising technique as it leveraged spatial information from the UAV images within the architecture of the learning framework by enforcing a local connectivity pattern between neurons of adjacent layers to incorporate the spatial relationships between features that comprised the shape of the Lomandra tussocks detected.
Journal ArticleDOI
Fire intensity, slopewash and bio‐transfer of sediment in eucalypt forest, Australia
TL;DR: Sediment movement (slopewash and bio-transfer), runoff, and organic matter movement (mainly leaf litter, ash and charcoal) were monitored on ten plots for a six-month period following bushfires in eastern Australia in the 1990s as discussed by the authors.
Journal ArticleDOI
Holocene palaeofire records in a high-level, proximal valley-fill (Wilson Bog), Mount Lofty Ranges, South Australia:
Solomon Buckman,Katherine C. Brownlie,Robert P. Bourman,Colin V. Murray-Wallace,Rowena H Morris,Terry J. Lachlan,Richard G. Roberts,Lee J. Arnold,J. H. Cann +8 more
TL;DR: An elevated valley-fill peat bog (Wilson Bog) near Mount Lofty, South Australia, failed in November 2005 following a flooding event, and exposed representative sections of the sediment infill.
Journal ArticleDOI
Environmental assessment of erosion following prescribed burning in the Mount Lofty Ranges, Australia
Rowena H Morris,Rowena H Morris,Rowena H Morris,Ross A. Bradstock,Ross A. Bradstock,Deirdre Dragovich,Meredith K. Henderson,Trent D. Penman,Bertram Ostendorf +8 more
TL;DR: In this paper, the authors focused on 10 prescribed burns conducted in the Southern Mount Lofty Ranges and used generalized additive modeling to determine the main significant environmental variables influencing the presence of sediment movement at 505 field-assessed sites.
Journal ArticleDOI
Fire-induced rock spalling as a mechanism of weathering responsible for flared slope and inselberg development.
TL;DR: In this article, the authors identify wildfire as a primary agent of flared slope development via fire-induced rock spalling around the periphery of inselbergs, and demonstrate that this is a common form of physical weathering in fire-prone environments.
