Historical insecticide applications for the treatment of forest insect pests from 1968 to 2017, in Nova Scotia and Newfoundland and Labrador, Canada

Key message  The geospatial dataset describes large-scale applications of insecticides to forests from 1968 to 2017 in the provinces of Newfoundland and Labrador (NL) and Nova Scotia (NS), Canada. The data was assembled to provide a historical

Water-based root exudates of Molinia caerulea (L.) Moench disrupt root nitrogen metabolism in Quercus petraea (Matt.) Liebl. seedlings with a fast negative effect on budburst

Key message Molinia caerulea (L.) Moench has been observed to significantly reduce budburst in Quercus petraea (Matt.) Liebl. seedlings through water-based M. caerulea root exudates. This suggests direct allelopathic effects between the two species. In terms of nutrient uptake, oak roots primarily

Identification of ash-associated understorey diversity—a lesson from historical vegetation records

Key message  Forest communities historically dominated by common ash (Fraxinus excelsior L.) were characterized by particularly high species richness in the understorey and included a distinct set of vascular plant species statistically associated with higher ash cover. These

Outbreaks of European spruce bark beetle dramatically altered Norway spruce-dominated stands with implications for volant wildlife in the Białowieża Forest, Poland

Key message  An outbreak of the European spruce bark beetle (Ips typographus L.) in spruce (Picea abies L.) dominated forest stands in the Białowieża Forest, Poland, has led to fundamental changes in forest characteristics. The species composition of regenerating stands

Comparative role of snags and stumps in promoting biological diversity—a case study from a mountain silver fir (Abies alba Mill.) forest

Key message  Differences in chemical properties and enzymatic activity between silver fir (Abies alba Mill.) stumps and snags in Polish mountain forests highlight their different effects on nutrient cycling. Our research underscores the significant differences in microbial activity

Optimisation of forest management under climate change in the French maritime pine (Pinus pinaster Aiton) forests

Key message  A modern portfolio optimisation was performed on simulation data to optimise management alternatives of maritime pine (Pinus pinaster Aiton), under climate change. The objective was to maximise the biological productivity while minimising the inter-annual variability, until 2100,

How to define and quantify substitution effects in the bioeconomy: a scoping review

Key message Research on substitution effects in the bioeconomy remains conceptually fragmented and methodologically narrow—focused predominantly on fossil-to-biomass material and energetic substitution, forest-derived biomass, carbon-related metrics, and single-method assessments. This limits its policy relevance. Comprehensive monitoring frameworks

UruDendro, a public dataset of 64 cross-section images and manual annual ring delineations of Pinus taeda L.

Key message  The automatic detection of tree-ring boundaries and other anatomical features using image analysis has progressed substantially over the past decade with advances in machine learning and imagery technology, as well as increasing demands from the

A decade-long study on mortality in European larch (Larix decidua Mill.), Japanese larch (Larix kaempferi (Lamb.) Car.) and their hybrid

Key Message This study, based on a clonal larch experiment under contrasting soil water conditions, showed that Japanese larch exhibited the highest drought-induced mortality, followed by the hybrid and European larch. Mortality was driven by low soil

Forest attribute maps: a support for small area estimation of forest disturbances

Key Message Forest attribute maps generated using national forest inventory and remote sensing data can be used to quantify forest attributes (i.e., growing stock volume, basal area) affected by disturbance events (like bark-beetle induced damage) through small
