Mitigating the adverse effects of climate change and worldwide urbanization is one of the main tasks of local authorities and city managers. As a long-term solution, urban and periurban forests have the potential to mitigate the impacts of climate change by providing ecosystem services such as removing air pollutants, mitigating the urban heat isla...

In the last decade, coniferous stands outside their natural range in Romania have experienced declines in both their health and growth and, in tandem with global climate trends, these forests are becoming even more threatened. We studied the relationship between tree growth and defoliation as an indicator of tree health. The data came from black pi...

O., 2023. Structure and diversity in a periurban forest of Bucharest, Romania. Ann. For. Res. 66(1): 139-153, 2023. Abstract: Mitigating the adverse effects of climate change and worldwide urbanization is one of the main tasks of local authorities and city managers. As a long-term solution, urban and periurban forests have the potential to mitigate...

Forests play an important role in biodiversity conservation, being one of the main providers of ecosystem services, according to the Economics of Ecosystems and Biodiversity. The functions and ecosystem services provided by forests are various concerning the natural capital and the socio-economic systems. Past decades of remote-sensing advances mak...

Research Highlights: Management of the risks forests are exposed to is based on the dynamics of the composition and structure of the stands and the forest. Background and Objectives: This study aimed to document the dynamics of the composition and structure of stands and forest in the Romanian Carpathians over the last five decades, as well as esti...

In general, the elaboration of the synthesis of water quality in Romania is based on the processing of a large volume of information coming from primary analytical data collected with a constant frequency by the organisms with a specific role in water quality monitoring. This study proposes a novel methodology for multi-criteria analysis aiming to...

Globally, ecosystems are constantly degrading as a result of pressures derived from human activities and climate change. For working towards the restoration of the natural balance, it is necessary to evaluate the deviations induced in the ecosystems, to identify where the changes took place, to know what is their amplitude and to decide where it is...

Research highlights: In this study, the possibility of developing predictive models for both individual trees and forest stands, based on information derived from digital surface models (DSMs), was evaluated. Background and objectives: Unmanned aerial systems (UASs) make it possible to obtain digital images with increased spectral and spatial resol...

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...

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...

Research Highlights: The present study case investigates the differences occurring when tree’s biophysical parameters are extracted through single and multiple scans. Scan sessions covered mountainous and hill regions of the Carpathian forests. Background and Objectives: We focused on analyzing stems, as a function of diameter at breast height (DBH...

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...

Forest stands are often parameterized by vegetation indices such as the Leaf Area Index (LAI). However, other indices (i.e. stand denseness, espacement, canopy density, canopy cover, foliage cover, crown porosity, gap fraction) may better characterize forest structure. Terrestrial and airborne active sensor data has been used to describe canopy str...

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...

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...
