This paper shows how the slow process of forestland restitution, which is unfolding in Romania since 1991 has eroded the threads of sustainable forest management by an insidious institutional amnesia (IA). The four symptoms of this harmful process (frequent reorganization, transition from paperwork to electronic media, fewer people motivated to join public services, and popularity of radical changes) were analyzed from the legal standing point as well as from practitioners’ perspective. After having described the legal process and the relative dependencies between laws and government ordinances we also showed that the three laws on forestland restoration (three fully operational laws and two bills submitted in 2019, one year before general elections) were produced by unintended policy arrangements. The legal loopholes of forestland restitution were described in details as well as the challenges brought about by nature conservation policy (Natura 2000 management plans v traditional forest planning), and the overwhelming bureaucratic burden developed to deter illegal logging, instead of fully implementing a modern system of forest watching based on volunteering. However, the main cause of IA is institutional unsteadiness which was inherited from the communist regime, and cannot be alleviated unless more involvement of professional foresters in politics.

As national governments continue developing bioeconomy strategies, the forest-based sector becomes increasingly important. Romania’s forest sector can be at the heart of a sustainable circular-bioeconomy transition. However, despite recently launching its national forest strategy, the country has yet to produce a comprehensive bioeconomy strategy where the forest sector is properly acknowledged and integrated. Here, we discuss the potential opportunities and challenges for developing a national circular–bioeconomy strategy that builds around the forest-based sector. Methodologically, we build on qualitative insights from two foresight workshops conducted with 16 international experts. Conceptually, we draw on recent forest-based circular-bioeconomy literature, which we synthesize and use to complement the insights provided by workshop participants. Three main key findings emerged from this analysis: (i) Several knowledge gaps related to biomass availability, carbon storage, biodiversity status, ecosystem services, or governance arrangements persist. (ii) A circular forest bioeconomy must focus on regional and rural development, including both traditional wood use, as well as new wood-based products. Finally, (iii) the transition to a forest-based bioeconomy requires substantial investments in areas such as forest infrastructure, education, and labor force. Forward-looking policies can address these challenges by fostering new ways of thinking, collaborating and researching the bioeconomy. We anticipate our article to be a starting point for more informed discussions around the role of forests and the forest-based sector in Romania’s future bioeconomy strategy. Furthermore, as work around the implementation of the national forest strategy has recently commenced, the ideas discussed here could help decision-makers better integrate and coordinate national and European forest policies with bioeconomy ambitions.

The paper presents how the Analytic Hierarchy Process can be used to select the most suitable combination of new forest roads to build onto a forested area provided that social or ecological aspects are not jeopardized. All important features worth being considered when a new network of forest roads is designed were grouped in three types of criteria, which are benefits, costs and risks. Further, in order to ease the pairwise comparisons between criteria, both benefits and costs have been divided into private and social, while the risks refer to the events that might be triggered or favoured by the construction of new roads, like habitat fragmentation, landslides in case of heavy rainfall during the construction phase or even illegal cuttings. The outcome consists of a series of benefit-cost-and-risk indices and benefit-cost ratios, one for each combination of forest roads, including the status quo. The method has been tested on three combinations of new forest roads already designed for a small forest management unit located in Prahova County, encompassing 838.0 ha of mountainous forest.

This paper describes a permanent research platform (PRP) designed and implemented in “Codrul secular Slătioara” and its surroundings (2205.85 ha), having also the role of introductory paper for future research articles based on data collected from this platform. “Codrul secular Slătioara” is known as one of the largest temperate mountainous intact forests of Europe and, in 2017, it was included in UNESCO World Heritage List, as part of the “Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe”. Moreover, the PRP overlaps other three scientific reserves, the share of strictly protected forests exceeding 70%. This platform has a multiple role, being developed for research, conservation and educational activities. The PRP was designed for an ecological analysis of the intact forest ecosystems. It contains 193 circular sample plots, each of them of 500 m², and it is structured on two levels. The first level contains 58 sample plots corresponding to a square grid of 500 × 500 m, stretching over the entire forested area, and the second level contains 135 plots, placed according to a square grid of 100 × 100 m, covering 136 ha within the core area of the UNESCO site. We measured the characteristics of 8296 living trees, 1743 standing dead trees, 1900 dead wood trunks, 3214 saplings, and the abundance–dominance indices of flora species. Thus, we identified 14 tree species, 17 shrub species, and 248 other cormophyte species forming the herbaceous layer. In terms of volume, the main tree species are Norway spruce, silver fir and European beech. The tallest species are Norway spruce (56 m) and silver fir (51 m). The average volume of living trees is 659 m³·ha⁻¹, with a maximum of 1441 m³·ha⁻¹. The mean total dead wood volume is about 158 m³·ha⁻¹, with sample plots where the total dead wood volume exceeds 600 m³·ha⁻¹. After presenting the results of preliminary data processing, the paper describes the main research topics to be further considered, based on the PRP, and the foresights related to the PRP’s monitoring and development.

The study zone includes one of the largest montane old-growth forests in Europe (Slatioara UNESCO site), and understanding the structure and functioning of sill intact forests in Europe is essential for grounding management strategies for secondary forests. For this reason, we set out to analyze the dependencies between aboveground biomass (AgB), tree species and size diversity and terrain morphology, as well as the relationship between biomass and diversity, since neither of these issues have been sufficiently explored. We found that tree species diversity decreases with increased solar radiation and elevation. Tree size heterogeneity reaches its highest mean values at elevations between 1001 and 1100 m, on slopes between 50 and 60 degrees. AgB is differentiated with elevation; the highest mean AgB (293 tonnes per hectare) is recorded at elevations between 801 and 900 m, while it decreases to 79 tonnes per hectare at more than 1500 m a.s.l. It is also influenced by tree species diversity and tree size heterogeneity, with the highest AgB reached in the most complex forest ecosystems in terms of structural diversity. We showed that intact temperate montane forests develop maximum biomass for optimum species diversity and highest size heterogeneity; all three are modulated mainly by elevation.
