in Armardeh, Baneh (Northern Zagros of Iran)]]>ValipourA. NamiraninanM. EtemadV. GhazanfariH. 1200931The aim of this study was to investigate relationships
between diameter and height with bark thickness of Lebanon oak (Quercus
libani Oliv.) and effect of geographical aspects on bark thickness.
This study was done in Northern Zagros forests, Western Iran.Socio-economic
problems as well as lack of information about forest situation are main
obstacles for proper management in these forests. One hundred and thirty
five sample discs were taken from 45 cut trees. Samples were measured
and analyzed with Minitab 14 and SPSS 15. Results from One-way analysis
of variance, demonstrated that there is no significant difference in bark
thickness in various aspects on trees. In order to indicate a proper model
for bark thickness estimation from diameter and height, mean of bark thickness
of various aspects, with highest correlation with diameter (R = 0.877)
and height (R = 0.74), was entered into model. Quadratic and linear equations
have best compatibility to estimation of bark thickness from concerned
factors. Mean of bark thickness was measured about 12.6 mm. Results can
use in management of these forest in order to determine potential values
of forest with consider bark as a non-wood forest product (because of
valuable raw materials) and effective factor on sprouting ability of oaks
(to make a forest regulation model based on coppice method).]]>Andrensek, S., B. Simonovska, I. Vovk, P. Fyhrquist, H. Vuorela and P.
