Relationships between Litterfall Amounts and Stand Attributes in a Quercus accutissima Stand

Composition, structure, and intra-stand spatial patterns along a disturbance severity gradient in a Quercus stand

Estimation of carbon sequestration potential stand coppice pertion oak (Quercus brantii) in kamfirooz (Fars provience).

In this study 30 coppice oak trees(Quercus brantii Lindl.) with least diameter of 5 centimeteres were chosen with random classification. Characteristics such as the number of sprouts, the diameter, total height, and the large and small diameter of crown were measured. For this purpose, the diameter ranges of the oak trees were devided into 5 cm classes and at least the growth factors of 3 trees...

Woody Regeneration in a Southern Appalachian Quercus Stand Following Wind Disturbance and Salvage Logging

In the eastern United States, the practice of salvage logging is common to reclaim economic losses and/or reduce fuel loading following a natural disturbance. A current hypothesis states that two disturbances in rapid succession (i.e., compounded disturbance) have a cumulative severity of impact and may displace the successional trajectory further than either disturbance occurring separately. O...

Relationship between Modelling Accuracy and Inflection Point Attributes of Several Equations while Modelling Stand Diameter Distributions

In this study, seven popular equations, including 3-parameter Weibull, 2-parameter Weibull, Gompertz, Logistic, Mitscherlich, Korf and R distribution, were used to model stand diameter distributions for exploring the relationship between the equations' inflection point attributes and model accuracy. A database comprised of 146 diameter frequency distributions of Chinese fir (Cunninghamia lanceo...

Prediction of Forest Stand Attributes Using TerraSAR-X Stereo Imagery

Consistent, detailed and up-to-date forest resource information is required for allocation of forestry activities and national and international reporting obligations. We evaluated the forest stand attribute prediction accuracy when radargrammetry was used to derive height information from TerraSAR-X stereo imagery. Radargrammetric elevations were normalized to heights above ground using an air...
