TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

Computer Graphics Forum, EarlyView.
Abstract We present TreeON, a novel neural‐based framework for reconstructing detailed 3D tree point clouds from sparse top‐down geodata, using only a single orthophoto and its corresponding Digital Surface Model (DSM). Our method introduces a new training supervision strategy that combines both geometric supervision and a differentiable shadow and ...

Molecular characterisation of Pinus sylvestris (L.) in Ireland at the western limit of the species distribution

BMC Ecology and Evolution
Background Scots pine (Pinus sylvestris L.) underwent significant population declines across much of northwest Europe during the mid-to-late Holocene and was thought to have become extirpated in Ireland from about 400 AD. However, most extant populations

Effects of restoration practices on biodiversity in temperate and boreal forests

Conservation Biology, EarlyView.
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Modelling biomass of young and dense Scots pine (Pinus sylvestris L.) dominated mixed forests in northern Sweden

Silva Fennica, 2014
Biomass models for the biomass of above-ground tree components of Scots pine ( L.), Norway spruce ( [L.] Karst.) and birch ( Roth and Ehrh.) in young dense Scots pine dominated forest stands in northern Sweden were constructed.

Management and tree dieback alter beetle assemblage structure and body size distribution in a temperate German forest

Ecological Entomology, EarlyView.
Forest management and climate‐induced tree dieback alter the structural characteristics of forests, which could subsequently lead to changes in the structure of beetle assemblages. Beetle assemblages in more open forests exhibited less even abundance distributions, with fewer, more dominant species (higher rates of decline (r), higher dominance (d ...

Small birches matter: Beetle diversity on burned birch and pine in boreal forests

Insect Conservation and Diversity, EarlyView.
Burned birch hosted higher beetle richness than burned pine. Higher beetle richness on birch was associated with its greater post‐fire mortality, with charred, dead birches attracting more specialized beetles. Retaining burned birch alongside pine can enhance saproxylic and pyrophilous beetle diversity after prescribed burning.

Linking EU habitat and species protection through favourable reference areas: Evidence from threatened saproxylic beetles

Insect Conservation and Diversity, EarlyView.
Threatened saproxylic beetles occurred significantly more often within EU forest habitats and in landscapes with high habitat density. Achieving Favourable Reference Areas substantially increased habitat availability and improved the projected conservation status of threatened saproxylic beetles.

Mikrostruktur dan Karakteristik Permukaan Kayu Pinus Scots (Pinus sylvestris L.) Termodifikasi Gliserol dan Asam Sitrat

Jurnal Ilmu Pertanian Indonesia
Scots pine (Pinus sylvestris L.) wood is one of the most popular timber export products. However, its low durability can reduce the potential and utilization of the wood. Chemical modification is one of the solutions to overcome this drawback.

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

Effects of planted European beech on the understory in Scots pine forests of Lithuania

iForest - Biogeosciences and Forestry, 2014
Understanding how the planting of non-native species impacts native vegetation is of most importance for forest management, as introduced species may alter environmental conditions with respect to soil composition, light intensity, and species ...
