evaluation variation trend in qualitative measures in natural even-aged stand in kheyroud forest
in this research with using of obtained information from a natural fraxinus the variation of quantities and qualitative measures of current stand in an 8 year period was conducted in chelir part of kheyroud forest. data collection was conducted by full callipering method in two periods of 1384 and 1392. during the period of study the parameters of dominant mean height and relative crown height ...
متن کاملa study on the dimensional characters of even-aged and mixed fraxinus excelsior stand (case study: chelir district, kheyrud forest)
knowing and conducting studies on size characters of trees is essential for assessing the tree volumeand/or other statistical parameters and also forest management. the characteristics of 529 treesincluding diameter at breast height (dbh) and total height were measured in an even-aged fraxinusstand for two periods from 2005 to 2012 in chelir district, a part of experimental kheyrud forest.resul...
متن کاملForest Growth Simulation: Tropical Rain Forest Stand Table Projection
The study on the tree growth for four species groups of commercial timber in Koh Kong province, Cambodia’s tropical rainforest is described. The simulation for these four groups had been successfully developed in the 5-year interval through year-60. Data were obtained from twenty permanent sample plots in the duration of thirteen years. The aim for this study was to develop stand table simulati...
متن کاملSpatial Variability of Turbulent Fluxes in the Roughness Sublayer of an Even-aged Pine Forest
The spatial variability of turbulent flow statistics in the roughness sublayer (RSL) of a uniform even-aged 14 m (= h) tall loblolly pine forest was investigated experimentally. Using seven existing walkup towers at this stand, high frequency velocity, temperature, water vapour and carbon dioxide concentrations were measured at 15.5 m above the ground surface from October 6 to 10 in 1997. These...
متن کاملStudy on the effect of forest stand distribution pattern on results of different estimators of the nearest individual distance method
The Nearest Individual Sampling Method is one of the distance sampling methods for estimating density, canopy cover and height of forest stands. Some distance sampling methods have more than one density estimator that may be skewed to the spatial pattern. Unless the stands of the trees under study have a random spatial pattern. Therefore, the purpose of this study was evaluating the effect of s...
