Species discrimination and individual tree detection for predicting main dendrometric characteristics in mixed temperate forests by use of airborne laser scanning and ultra-high-resolution imagery.
TL;DR: The results indicate a higher individual tree detection rate and subsequently a more precise estimation of dendrometric parameters for Norway spruce compared to beech trees located in spruce-beech even-aged mixed stands.

TL;DR: State-of-the-art simulations models were used to evaluate the utility of C-, L- and P-band synthetic aperture radar (SAR) sensors within an integrated Earth-Observation monitoring system for beech, oak and coniferous forests in Romania, showing differentiated sensitivity to vegetation water content, leaf area index, and forest disturbance depending on SAR wavelength and forest structure.

TL;DR: In this paper, a comparison analysis of two data collection methods that can be used in order to obtain reference ground truth data for forestry is presented, a conventional method that uses specific equipment such as Field Map system, caliper and vertex inclinometer and a modern method based on terrestrial laser scanning (TLS) technology.
Height Extraction and Stand Volume Estimation Based on Fusion Airborne LiDAR Data and Terrestrial Measurements for a Norway Spruce [Picea abies (L.) Karst.] Test Site in Romania
TL;DR: In this paper, the authors used the Canopy Maxima algorithm for individual tree detection together with biometric field measurements and individual trees positioning to analyze the efficiency of individual tree identification and stand volume estimation from LiDAR data.

TL;DR: In this paper, a modeling approach based on logistic regression using historical fire observations has been developed based on environmental, socio-economic and demographic data availability at national scale for forest fire risk analysis and fire risk zoning over Romania.
