Regeneration of Athrotaxis Selaginoides and Other Rainf'orest Tree Species on Landslide in Tasmania
نویسنده
چکیده
Seedling surveys indicated that landslide faces provide opportunities for Athrotaxis seialiinoides and Nothr'/m'U" to regenerate in lhamnlc and high altitude callidendrous rainforest. The spatial distribution of mature A. stems at some sites suggests that they have originated on past landslides. Leptospermum scoparium and Eucalyptus vemicosa seedlings were also present at some of the sites investigated. Therefore, landslides may provide regeneration opportunities for these species in rainforest communities in the absence of fire. The physical attributes of A. seiaginoides suggest that the species would be advantaged by canopy disturbance of the scale caused by landslides as opposed to smaller treefal! gaps. The cooler climate, higher levels of slope inslabi.lity, avalanches and snowstorms during the last glacial would have been well suited to this species.

Modern pollen from small hollows reflects Athrotaxis cupressoides density across a wildfire gradient in subalpine forests of the Central Plateau, Tasmania, Australia
Pollen assemblages from 50 small hollows were used to resolve fire-caused vegetation patterns in a ~2-km2 subalpine landscape on the Central Plateau of Tasmania, Australia. Sites were characterized by varying abundance of the dominant tree species, Athrotaxis cupressoides, reflecting mortality from a wildfire that occurred 53 years prior to sampling. Sites were classified a priori based on fire...

Global increases in fire frequency driven by anthropogenic greenhouse emissions and land use change could threaten unique and ancient species by creeping into long-term fire refugia. The perhumid and mountainous western half of Tasmania is a globally important refugium for palaeo-endemic, fire intolerant lineages, especially conifers. Reproductive strategy will be crucial to the resilience of t...

The regeneration is one of the most important phenomena in forest ecosystems and the most important factor of development and sustainability of forests. Assessment of the regeneration is one of the best criteria for monitoring forest function stability. The aim of this study was to investigate the spatial variability of regeneration diversity and its relationship with tree species diversity in ...
