Dendrogeomorphology is the application of tree-ring analysis for the dating of geomorphic processes. Although defined elsewhere, Shroder (1978, 1980) provided the foundation and methodologies for dendrogeomorphology that continue to underpin the discipline more than 30 years after the publication of his research papers. His process-event-response methodology and development of a semi-quantitative index number are techniques employed or discussed in virtually every recent paper within the field of dendrogeomorphology.

In terms of the spatiotemporal reconstruction of geomorphic processes the application of tree-ring analysis has the highest level of temporal resolution in geomorphology. Dating and the resulting reconstructions can be assigned to exact calendar years, sometimes even to specific seasons. To guarantee this,one has to take into account that there are great differences between methods in the field and other tree-ring related fields of research. Following site selection a detailed relief analysis and process must be carried out in order to determine and select those trees obviously disturbed by these processes. The method of sampling is of the utmost importance. Selection of the samples must be based on the estimated kind of disturbance and therefore corresponds to the specific disturbance of a given species and not to the site being investigated. Furthermore,in order to be able to accurately date the disturbances it is absolutely essential to produce a local reference chronology.

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
