Effects of phenotypic selection on height-diameter ratio of Norway spruce and Scots pine in Sweden

open access: yesSilva Fennica, 2018
Genetically improved Norway spruce ( (L.) Karst.) and Scots pine ( L.) are extensively used in operational Swedish forestry plantations. However, relatively little is known about the stem slenderness (height-diameter ratio) of genetically improved ...

Estimation of fire resistance of partially logged pine stands in the Krasnoyarsk forest-steppe [PDF]

open access: yesСибирский лесной журнал, 2019
Scots pine forests are extremely fire hazardous. They show high fire frequency compared to other forest formations. This is due to their high natural fire danger, as along with high recreation activity, which is determined by a fairly dense road network ...

Performance of lodgepole pine and Scots pine in field trials located in north-west Russia

open access: yesSilva Fennica, 2017
Mortality, stem growth and quality of lodgepole pine ( var. ) originating from the six Swedish seed orchards and local Scots pine ( L.) were estimated in four field trials established in the Komi Republic (north-west Russia). A randomized row-plot design

Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

open access: yesFire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.

Maturity of Scots Pine Cones

open access: yesThe Forestry Chronicle, 1979
Cone and seed maturity of Scots pine (Pinus sylvestris L.) were evaluated for three seed years and several plantations in prairie Canada. Both specific gravity and moisture content provided reliable measures of cone maturity and were directly related to viability of the seed produced.

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests

open access: yesOikos, EarlyView.
The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.

Afforestation in Serbia in the period 1961-2007 with special reference to Austrian pine and Scots pine [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2009
The significance of afforestation in Serbia is high because only in this way the forest area can be increased and brought to the level which corresponds to the demands of the population.

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding

open access: yesPeople and Nature, EarlyView.
Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...
