Article
Full-text available
Protected areas pose a major interest in the current context in which natural habitats are very fragmented as a result of economic development. The ROSCI0076 Dealul Mare-Hîrlău site represents the largest protected area from Moldova’s Plateau where forest habitats occupy a majority surface. A total number of 10 Natura 2000 forest habitats were iden...

Dead wood (DW) is an important component of sustainable forest management and climate change mitigation. Three research plots (each with an area of 1 ha), located in virgin forests in the Southern Carpathians (Semenic P20, Retezat–Zănoaga, and Făgăraș–Șinca), were installed in order to study the synergies between DW and climate change mitigation ef...
Chapter
O período entre 2018 e 2022 mostrou-nos que o problema dos incêndios à escala global não está a diminuir, antes pelo contrário. Parece que as consequências das alterações climáticas já estão a afectar a ocorrência de incêndios florestais em várias partes do Mundo, de uma forma que só esperaríamos que acontecesse vários anos mais tarde. Em muitos pa...
Article
Full-text available
While products generated at global levels provide easy access to information on forest growing stock volume (GSV), their use at regional to national levels is limited by temporal frequency, spatial resolution, or unknown local errors that may be overcome through locally calibrated products. This study assessed the need, and utility, of developing l...
Article
Full-text available
The current paper tested the hypothesis that TLS through its high accuracy, increased spatial resolution, portability, equivalenting în high temporal resolution, automated processing and unlimited revisiting capabilities of the scene once record ed, might represent the best available technology for phenological evaluation. Phenology observations r...
Article
Full-text available
Modeling and forecasting forest evolution in the context of climate and socio-economic change is a challenge for the scientific community. This paper aims to calibrate the LANDIS-11 simulation model for a type of forest ecosystem by introducing climate scenarios and forecast of its dynamics under different forest management practices. The area use...
Article
Full-text available
Assessing the possibility of implementing a national forest monitoring system based on Earth Observation technologies Programs developed in national bio-monitoring networks, such as ICP-Forests, have limitations due to local micro-climatic variations that are difficult to assess. Therefore, new technologies (e.g., remote sensing) are needed to asse...
Article
Full-text available
Timely and accurate spatial explicit forest fire risk assessment and mapping is essential for forest fire prevention and suppression preparedness, firefighting resources allocation, and efficient multi-level fire management policies. This paper describes the application and validation of an approach for forest fire risk analysis and fire risk zonin...
Article
This study aims to investigate the combined use of two types of remote sensing data — ALS derived and digital aerial photogrammetry data (based on imagery collected by airborne UAV sensors) — along with intensive field measurements for extracting and predicting tree and stand parameters in even-aged mixed forests. The study is located in South West...
Article
Natural and anthropogenic disturbances pose a significant threat to forest condition. Continuous, reliable and accurate forest monitoring systems are needed to provide early warning of potential declines in forest condition. To address that need, state-of-the-art simulations models were used to evaluate the utility of C-, L- and P-band synthetic ap...
Article
Full-text available
This study aims to present a comparison analysis of two data collection methods that can be used in order to obtain reference ground truth data for forestry-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. The resear...
Article
Even though pedunculate oak (Quercus robur L.) and grayish oak (Quercus pedunculiflora K. Koch) have different ecological requirements, they have been considered as having low differentiation at the level of morphological traits and genetic variation. The leaf morphology for 862 trees has been assessed in 16 natural populations, seven of Q. robur,...
Article
Full-text available
In the last three decades, an increase in the annual average air temperature by 0.5 °C was recorded in Romania. By 2040, it is expected that the average temperature will increase by 1.3 °C and the average amount of rainfall will decrease by 10%. In this context, species able to adapt to the contemporary climate change should be promoted. One of the...
Article
Full-text available
Amorpha fruticosa (false indigo bush or indigobush) is one of the most important invasive terrestrial plant species (ITPS) found in Romania alongside Ailanthus altissima, Acer negundo, and Fraxinus pennsylvanica. In Romania, given its ecological requirements and initial use (degraded land reclamation), it’s found especially in the floodplains of th...
Article
Full-text available
The objective of this study was to analyze the efficiency of individual tree identification and stand volume estimation from LiDAR data. The study was located in Norway spruce [Picea abies (L.) Karst.] stands in southwestern Romania and linked airborne laser scanning (ALS) with terrestrial measurements through empirical modelling. The proposed meth...

The Member States of the European Union have committed to the maintenance and protection of forest lands. More precisely, the Member States aim to ensure the sustainable development and management of the EU's forests. For 2013, Eurostat's statistics about primary and secondary wood products in the European forest land (65% thereof privately owned)...

As part of the 2012 Land Use/Land Cover Area Frame Survey (LUCAS), topsoil samples were collected in Bulgaria and Romania using the same methodology as for other EU Member States in an equivalent survey carried out in 2009. In total, 664 Bulgarian and 1384 Romanian samples were collected which enabled a comparative assessment of topsoil properties...
Article
Full-text available
The paper presents the basic ideas that leaded to the conceptualization and development of an informatics system for planning the pastoral beekeeping in Romania. This informatics system integrates administrative and geographic information database, average multiannual climatic data, melliferous potential calculation, and beekeepers and beehives dat...
Article
The main purpose of this study is to analyze the possibility of stand biomass evaluation based on biometric measurements from airborne laser scanning data in a spruce forest test area. Data fusion of airborne laser scanning, and aerial orthoimagery (0.5 m spatial resolution), as well as the use of FieldMap equipment in the measurement of reference...
Conference Paper
Full-text available
The aim of this study was to identify forest areas vulnerable to the negative impact of the biotic and abiotic factors and to develop GIS based maps of these areas at national level. These maps will help forest decision makers to improve risk management measures. The data used to develop the maps was provided by the National Forest Administration....

Project
EO-ROFORMON aims to prototype a novel national forest monitoring and forecasting system based on the integration of active (radar) and passive (optical) Earth-Observation (EO) sensors calibrated with in situ data. The project focuses on retrieving indicators related to forest condition/status (e.g. defoliation) and degradation (e.g. logging activity, wind throws, fires). A second component of the project is focused on forest landscape modelling using the LANDIS-II. Through this component future trends are modelled starting from past and present forest condition, change drivers, management practices, and natural and anthropogenic disturbances.
