Regional Variability of the Romanian Main Tree Species Growth Using National Forest Inventory Increment Cores

Spatial variability and estimation of tree attributes in a plantation forest in the Caspian region of Iran using geostatistical analysis

This research was conducted to investigate spatial variability and estimate tree attributes in a plantation forest in the Caspian region of Iran using geostatistical analysis. Sampling was performed based on a 50m?125m systematic grid in a maple stand (Acer velutinum Boiss) 18 years of age using circular samples of 200m2 area. Totally, 96 sample plots were measured in 63 hectares and 14.25 he...

Assessment of the Main Natural Disturbances on Norwegian Forest Based on 20 Years of National Inventory

The re-measurement of permanent forest inventories offers a unique opportunity to assess the occurrence and impact of forest disturbances. The present study aims at exploring the main forest damages in Norway based on the extensive data of several consecutive national forest inventories during the period 1995-2014. Five of the most common disturbance agents in Norway are selected for analysis: ...

Selecting tree species for testing climate change migration hypotheses using forest inventory data

The lack of objective tree species lists hinders the assessment of climate change effects on tree species distributions. The goal of this studywas to develop and evaluate criteria for selecting tree species used in large-scale tree migration monitoring efforts. The results of this study indicate that tree migration conclusions are highly dependant on the species selected for examination. It was...

Feature-based Tree Species Classification Using Hyperspectral and Lidar Data in the Bavarian Forest National Park

The Bavarian Forest National Park, established in 1970, is a unique area of forests with large nonintervention zones, which promote a large-scale rewilding process with low human interference. Thus, the National Park authority is particularly interested in investigating the structure and dynamics of the forest ecosystems within the park. However, conventional forest inventories are timeconsumin...
