We reconstructed wildfire history from fire-scars to detect the influences of climatic variability and land-use change on wildfire dynamics in the lodgepole pine (Pinus contorta var.  latifolia Engelm.) forests of Jasper National Park in the Canadian Rocky Mountains.  New original analyses were performed on 170 cross-section samples collected in the 1970s from 52 sites around Jasper, Alberta.  The updated fire record reveals that fire occurrence was highly variable: site-lev...

The Tiger Creek Preserve in central Florida has one of the highest concentrations of threatened and endangered plants and animals in the United States.  Historically it was probably a longleaf pine savanna, but fire exclusion in recent decades has almost certainly led to increased basal area by mid-story oaks (mainly Quercus geminata and Q. laevis).  Determining the date of establishment of these trees, as well as the early fire history of the site, would provide evidence to supp...
