This is a fantastic story. Anyone who has walked in the mountains of central and western Tasmania is probably familiar with the King Billy Pine (Athrotaxis selaginoides). Individual trees can live for more than 1,00 years. It is one of the conifers that are endemic to Tasmania and exists only within a very limited range of habitat. Fire threatens the species (one third of its habitat was burnt in the twentieth century), and climate change is expected to increase the severity of fire seasons in future.
The following article outlines a research project that used core samples from King Billy trees to develop a better understanding of climate in Tasmania in previous centuries. It is available here.
