Restoration of Damaged Stands : Dealing with the
Eastern hemlock (Tsuga canadensis (L.) Carr.) is an evergreen conifer that is widely dispersed in the northeastern United States. Loss of the hemlock component in the eastern forest due to the introduced hemlock woolly adelgid (Adelges tsugae) will have long-term consequences for terrestrial and aquatic ecosystems. Some of the functional attributes of hemlock (vertical structure diversity, ever...
متن کاملNutrient Dynamics and Decomposition rate of Norway Spruce Needles in Stråsan and Lajim stands
Climate changes due to changes in a habitat leads to differences in the rate of decomposition and nutrient dynamics of leaflitters, which has many effects on the controlling factors of the decomposition process. In the present study, the rate of decomposition and nutrient dynamics of Norway spruce was evaluated for 363 days in the two forestation sites in the natural and foreign habitats, ...
متن کاملEstimating tree mortality of Norway spruce stands with neural networks
Within forest growth modeling LOGIT models are used to predict individual tree mortality. In this paper we present, Multi-Layer Perceptron, Learning Vector Quantization and Cascade Correlation networks as different formalisms for mortality predictions. The data set for parameterizing the LOGIT model and training the different neural network types comes from the Austrian National Forest Inventor...
متن کاملVariability of soil chemical characteristics in Oak stands with different dieback
Determination of soil chemical properties variability that affected tree tolerance to stresses can help to manage this environmental phenomenon. In this investigation, for detection of this variation trend, area of affected decline oak trees divided to four groups of control (without Oak decline), slight, middle and severe Oak decline based on tree and branch number per soil surface unit. In ea...
