Standardised chronology for all sites. Method of standardisation was a 128 year 50% cut-off smoothing spline. Top panel: site at 100m; second panel: site at 400m; third panel: site at 600m; bottom panel: site at 900m |

Project summary:
Samples from within the Warra LTER site. Four chronologies have been developed from Phyllocladus aspleniifolius sampled along an altitudinal gradient.
Preliminary samples taken from Athrotaxis selaginoides indicate that cross-dating is present in this species, with further sampling necessary in order to develop a chronology.
A brief examination of the rings from a sample of Eucalyptus subcrenulata suggests that this species, at high elevation, is worth investigating in relation to developing an accurately dated fire history for the area. Phyllocladus aspleniifolius and Athrotaxis selaginoides do not appear to cross-date with one another, suggesting cambial growth is influenced by different external stimuli.
Methodology: Tree ring analyseswere performed for three different species: Phyllocladus aspleniifolius; Athrotaxis selaginoides and Eucalyptus subcrenulata.
Datasets: None available.
