Don) based on its tree-ring data and age stand distribution at Langtang National Park, Central Nepal. Climatic response on radial growth, recruitment of <em>A. spectabilis </em>and its age distribution are carried out. The average tree density of the species in the study area (total 48 plots of 20 m x 20 m) was 236 no/ha while that for sapling and seedling in the study area was 255 and 350 no/ha, respectively. The stand character and age distribution of the species showed a high level of recruitment in the recent decades, with decreased in average age along with increased altitude. Tree-growth climate relationship showed negative response with temperature of March-May. Upward advancement of tree line is expected in the coming recent decades though not necessarily uniform through the line.</p><p>DOI: <a href="http://dx.doi.org/10.3126/njst.v12i0.6506">http://dx.doi.org/10.3126/njst.v12i0.6506</a></p> <p>Nepal Journal of Science and Technology 12 (2011) 220-229</p><p> </p>}, journal={Nepal Journal of Science and Technology}, author={Gaire, Narayan P and Dhakal, Yub R and Lekhak, Harish C and Bhuju, Dinesh R and Shah, Santosh K}, year={2012}, month={Jul.}, pages={220–229} }
