Instrumental Records

We examined Toona ciliata M.Roemer (Australian red cedar) for its potential to deliver annually resolved tree-ring proxy data. Such proxies are valuable and sought-after sources for reconstructing climate beyond instrumental records, especially in Australia. T. ciliata was chosen because it is one of the few deciduous tree species in Australia experiencing a seasonally dormant period of the cambium. This was confirmed by a preliminary tree-ring analysis which revealed distinct growth rings. Because of initial uncertainties regarding reliable annual growth rings in the wood of T. ciliata, a dendrometer-band study was conducted in addition to the tree-ring analysis. Stem increments revealed a common period of dormancy during winter and the measurements were found to correlate with both precipitation and temperature, depending on the site. For the first time, our tree-ring analysis demonstrated that samples from different individuals can be cross-dated and the resulting site index from Upper Kangaroo Valley (New South Wales) has the potential to reconstruct early season temperatures and late-season rainfall.

Ring Analysis

Tree ring analysis is one of the most useful methods in volume and biomass estimation especially of the conifer trees. Ring width and ring density are important parameters in dendrochronological research. The present research was carried out with the aim of estimating the radial and volumetric growth of the Japanese Cypress trees (Chamaecyperis obstusa and C. pisifera). Destructive method was used while collecting the wood samples from the selected trees. Ring width and ring density were measured using soft X-ray densitometry method using micro-densitometer. Computer programme, developed by the Forestry and Forest Products Research Institute, Japan was used to analyze the ring with and ring density data. The average ring width of the Chamaecyparis spp. was found to be about 3.4 mm at the age of 30 years. However, two types of growth pattern were observed in the trees. Average radial growth was about 5% every year during the first 20 years of the tree age, whereas, the average radial growth was negative during the age of 20–30 years. Average density of the tree rings were increased by about 11% in each height of the trees starting from the ground. Similarly, the stem density decreased by about 3.4% annually along the radial direction from the pith.DOI: http://dx.doi.org/10.3126/banko.v22i2.9197Banko Janakari: A Journal of Forestry Information for NepalVol. 22, No. 2, 2012 November Page: 36-42 Uploaded date: 12/1/2013

Ring Analysis

A landslide in Clearwater Lake has been dated to spring of 1933 from tree-ring analysis (reaction wood, growth suppression, and corrosion scars). From the 52 sampled trees, seven peak periods of movement were registered within the site before landslide occurrence: 1785, 1815, 1827, 1829, 1852–1853, 1871–1872, 1897, and 1926. After a slow progression lasting 200 years, the slope movements accelerated in 1926, as indicated by suppressed growth rings. It is proposed here that the landslide was the outcome of a long-term slope development partly controlled by climate (precipitation). Postdisturbance forest regeneration (between 1950 and 1976) on the newly exposed substrate is also related to climatic conditions.
