Effect of fire weather, fuel age and topography on patterns of remnant vegetation following a large fire event in southern California, USA

摘要: Large fire events in southern California have burned thousands of hectares over the past decade. Landscape pattern and natural system processes are shaped by these large conflagrations, thereby influencing ecological structure functioning region. Unburned vegetation remnants can be used to assess general fuel consumption provide valuable information regarding behaviour, weather effects post-fire regeneration. For this study, unburned was mapped at a very fine spatial resolution based on semi-automatic classification airborne large-format multispectral image data compared across different environment zones within 2003 Cedar Fire burn perimeter. metrics were characterise patches for section affected Santa Ana conditions that under non-Santa conditions. Maps remnant associated landscape two sections shrubland community type, topography age-class strata using inferential statistics. Key findings reveal more larger, rounder section. Pre-fire stand age greater than 6 years showed little effect amount or
