This study investigated the role of present vegetation in improving air quality in Bucharest (Romania) by analyzing six years of air quality data (𝑃𝑀10 and NO2) from multiple monitoring stations. The target value for human health protection is regularly exceeded for 𝑃𝑀10 and not for NO2 over time. Road traffic has substantially contributed (over 70...

With the intensification of the effects of climate change, the urgent need to address their drivers, especially greenhouse gas emissions, has become essential. In this context, forests offer a robust solution, with their potential to store and mitigate carbon emissions. However, striking a balance is critical given the significant economic contribu...

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...

Climate change’s negative effects, such as rising global temperatures and the disruption of global ecological ecosystems as a direct effect of rising carbon emissions in the atmosphere, are a significant concern for human health, communities, and ecosystems. The condition and presence of forest ecosystems, especially those in peri-urban areas, play...

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...

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...

The structure and functioning of temperate forests are shifting due to changes in climate. Foreseeing the trajectory of such changes is critical to implementing adequate management practices and defining long-term strategies. This study investigated future shifts in temperate forest species composition and abundance expected to occur due to climate...

Research Highlights: Carpathian forests hold high ecological and economic value while generating conservation concerns, with some of these forests being among the few remaining temperate virgin forests in Europe. Carpathian forests partially lost their original integrity due to their management. Climate change has also gradually contributed to fore...

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...

The stand structure of a virgin forest situated at an average altitude of 1130 m a.s.l. in the Milea Viforâta Nature Reserve (Southern Carpathians, Romania) was investigated to determine the specific development phases of the forest and understand how they influence the stand structure, with the aim of providing optimal solutions and structural mod...

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...

Background and Purpose: Romania’s forests are of globally significant value due to their natural characteristics, as similar forests in some other parts of the world have been lost forever. These types of forests, so-called "virgin" and "quasi-virgin (old growth)" forests, are also identified in the Buzau Mountains, which are part of the Eastern Ca...

Forest health status is negatively influenced by climate change, air pollution and other disturbances. Extreme droughts reduce stand productivity, increase vulnerability to pests, and can even provoke mortality. Growth dynamics at tree and forest stand levels are considered the main indicators of stability and productivity in forest ecosystem struc...

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...

Interactions between people and ecological systems, through leisure or tourism activities, form a complex socio-ecological spatial network. The analysis of the benefits people derive from their interactions with nature—also referred to as cultural ecosystem services (CES)—enables a better understanding of these socio-ecological systems. In the age...

On the background of climate changes, in the last period concerns regarding the forest vegetation have increased due to its role in improving the effects of these climatic changes. The stands from meadow have a great importance because they represent habitat and food source for a large variety of living beings. In the last decade, the occupied surf...

Knowledge of intra-annual tree growth dynamics allow a better understanding of tree reaction to short term climate variation. The main objective of our study was modelling intra-annual dynamics of basal area increment (BAI) in four level II plots in Romania, composed of pedunculate oak (Quercus robur L.), sessile oak (Q. petraea [Matt.] Liebl.), No...
