This study aims at establishing robust height-diameter models for Chir pine (<em>Pinus roxburghii</em>) trees using regression techniques. Among the twelve non-linear models fitted to height-diameter data from twentythree Chir pine stands in Parbat and Shyangja districts, Hossfeld’s model accounted for the largest proportion of height variations (R<sup>2</sup><sub>adj</sub> = 86%), and appeared to be biologically most realistic. This model can be applied to similar stand conditions from where study data were procured.</p> <p><strong>Keywords</strong>: Chir pine; height-diameter models; model evaluation; stand attributes</p> <p>DOI: 10.3126/banko.v19i2.2978</p> <p><em>Banko Janakari</em>, Vol. 19, No.2 2009 pp.3-9  </p>}, number={2}, journal={Banko Janakari}, author={Sharma, RP}, year={2010}, month={Apr.}, pages={3–9} }
