Narratives of ‘home landscapes’ guide stewardship practices among Swedish forest owners

People and Nature, EarlyView.
Abstract Production forests play an important role in addressing many of our current sustainability challenges. Therefore, how these forests are managed and what motivates the people who are managing them are important for sustainability. 47 per cent of forests in Europe are privately owned.

Changes in the extent and structure of Norway spruce stands in the Ukrainian Carpathians based on forest survey data from 1988 to 2018

Central European Forestry Journal
This study investigates dynamics of Norway spruce stands in the Ukrainian Carpathians in 1988–2018. Cultivation of Norway spruce has altered forest composition at the expense of site-adapted species.

Difference on cone size preferences between two coniferous species by Great Spotted Woodpecker (Dendrocopos major) [PDF]

PeerJ, 2017
The number of species that specialize in pre-dispersal seed predation is relatively small. Examples of specialized pre-dispersal seed predators adapted to feeding on closed cones include vertebrate species like Crossbills, Squirrels, Nutcrackers and ...

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Large‐scale characterization of horizontal forest structure from remote sensing optical images

Remote Sensing in Ecology and Conservation, EarlyView.
Sub‐meter resolution remote sensing data and tree crown segmentation techniques hold promise in offering detailed information that can support the characterization of forest structure from a horizontal perspective, offering new insights in the tree crown structure at scale.

Species selection in areas subjected to risk of root and butt rot: applying Precision forestry in Norway

Silva Fennica, 2022
Norway’s most common tree species, Picea abies (L.) Karst. (Norway spruce), is often infected with Heterobasidion parviporum Niemelä & Korhonen and Heterobasidion annosum (Fr.) Bref.. Because Pinus sylvestris L.

Ozone detoxification of steam-pretreated Norway spruce [PDF]

Biotechnology for Biofuels, 2015
Pretreatment of lignocellulose for biochemical conversion commonly results in formation of by-products that inhibit microorganisms and cellulolytic enzymes. To make bioconversion processes more efficient, inhibition problems can be alleviated through conditioning.

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Effects of silver fir (Abies alba Mill.) on the humus forms in Norway spruce (Picea abies (L.) H. Karst.) stands

Journal of Forest Science, 2018
The effects of silver fir (Abies alba Miller) on the soil compared to Norway spruce (Picea abies (Linnaeus) H. Karsten) were evaluated. Altitude of the study site is 790 m a.s.l., mild slope of 10° facing SW, forest site is spruce-beech on acid soil. The

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.
