Title : Modelling growing space requirement for Alnus nepalensis D. Don in Nepal Material Type: printed text Authors: SHARMA, R.P., Author Publication Date: 2006 Article on page: 30-36 p. Languages : English (eng) Keywords: Alnus nepalensis crown model growing space stocking limit basal area density Abstract: Relationship between crown diameter and stem diameter of individual trees can be translated into mathematical model, and used to generate information of growing space requirement for individual trees and crown competition index for growth models. Nine different crown diameter prediction models were developed using inventory data of Alnus nepalensis trees from a part of Parbat and Syanja districts in Nepal. Among those developed, a non-linear three parameter-based model (W = β0 {1 – exp( - β1D)}β2) explained the greatest proportion of variations of crown diameter (R2adj = 0.78), and showed desirable behaviour of flexibility and robustness. An individual tree growing space model was then derived from crown model to generate important information of shocking limits and stand basal area density for monoculture plantation or natural stands of Alnus nepalensis. Because of its flexibility, crown model is seemed potentially useful for extrapolation purpose also. However, the model cannot be applied for buttressed, wolfed and malformed trees.

Title : Modelling height-diameter relationship for Chir pine trees Material Type: printed text Authors: SHARMA, R.P., Author Publication Date: 2009 Article on page: 3-9 p Languages : English (eng) Keywords: Chir pine height-diameter models model evaluation stand attributes Abstract: Tree height-diameter relationship can be used as an important input component in growth
and yield models, and description of stand dynamics. This study aims at establishing
robust height-diameter models for Chir pine (Pinus roxburghii) 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 (R2
adj
= 86%), and appeared to be biologically
most realistic. This model can be applied to similar stand conditions from where study
data were procured.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=10

Title : Modelling height-diameter relationship for Pinus wallichiana trees for Lete and Kunjo of Mustang district Material Type: printed text Authors: B.H. Wagle, Author ; SHARMA, R.P., Author Publication Date: 2011 Article on page: 13-23 p. Languages : English (eng) Keywords: Blue pine height-diameter models modelling Mustang district Abstract: Quantification of height-diameter relationship helps in better understanding of stand dynamics.
Height-diameter models can be used as necessary inputs to growth and yield models and growth
simulation systems. The researchers developed height-diameter models with 364 Blue pine (Pinus
wallichiana) tree data from Lete and Kunjo Village Development Committees (VDCs) of Mustang
district. Eighteen non-linear models were calibrated, among which, Weibull model described the
largest proportion of height
variation (R2
adj
= 0. 9362). Gunary and Chapman-Richards’ models also appeared
almost identical to Weibull model in terms of fit statistics and graphical appearance. The
researchers recommend Weibull model for predicting total heights of Blue pine trees for the VDCs
covered by the study.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=2
