Short summary
Tree-ring records provide a unique window into past climate variability. However, there are few such records from the Australian mainland. We present results from nine cross-sections of an alpine tree species from the Victorian Alps from 1929–1998. The tree-ring widths have significant correlations with winter temperature, precipitation and snow depth. The intensity of reflected blue light from the wood surface shows a strong response to growing season temperature and winter precipitation.
