Breeding of Picea mariana (Mill.) B.S.P.: seed orchard and clonal approaches.

Silva Fennica, 1991
During the past 30 years, genetics research has accumulated much information on black spruce (). The adoption of less intensive and faster plustree selection, establishment of seedling seed orchards and family selection significantly increased the rate ...

Visual Recognition Software for Binary Classification and Its Application to Spruce Pollen Identification. [PDF]

PLoS ONE, 2016
Discriminating between black and white spruce (Picea mariana and Picea glauca) is a difficult palynological classification problem that, if solved, would provide valuable data for paleoclimate reconstructions.

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Short‐term growth response of jack pine and spruce spp. to wood ash amendment across Canada

GCB Bioenergy, 2020
Wood ash amendment to forest soils contributes to the sustainability of the growing bioenergy industry, not only through decreased wood ash waste disposal in landfills but also by increasing soil/site productivity and tree growth.

Soil carbon storage and stability controlled by site properties more than forest management in a humid boreal forest

Soil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.
Abstract Soils of managed boreal forests are a significant carbon (C) reservoir, and maintaining or increasing their ability to store C could play an important role for climate change mitigation. We investigated the effects of forest logging through clearcut and partial cut compared to forest conservation on total soil C stocks, particulate organic ...

Prediction of Escaped Powerline‐Caused Fires in Alberta, Canada

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Powerlines have increasingly become a source of wildfire ignitions, contributing to more escaped and catastrophic fires during extreme fire weather. Temporary power shutoffs are implemented to reduce this risk, yet decisions on their implementations are often based on limited scientific evidence.

Bioactive Molecules from Myrianthus arboreus, Acer rubrum, and Picea mariana Forest Resources

Molecules, 2023
Forest trees are the world’s most important renewable natural resources in terms of their dominance among other biomasses and the diversity of molecules that they produce.

Recovery of forest‐floor vegetation after a wildfire in a Picea mariana forest [PDF]

Ecological Research, 2013
Abstract We aimed to detect the trajectories of forest‐floor vegetation recovery in a Picea mariana forest after a wildfire. Since fire severity in boreal forests is expected to increase because of climate changes, we investigated the effects of ground‐surface burn severity,

Advancing Satellite Solar‐Induced Chlorophyll Fluorescence Data Assimilation in Land Surface Models: An Assessment Over Boreal Evergreen Needleleaf Forests

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Boreal forests represent about 20% of the global forest carbon sink and contribute to climate change mitigation, yet land surface models (LSMs) struggle to simulate their gross primary production (GPP). Space‐borne observations of solar‐induced fluorescence (SIF) have been used to improve LSM GPP through data assimilation.

Black spruce (Picea mariana) seed availability and viability in boreal forests after large wildfires

Annals of Forest Science, 2023
Key message Black spruce (Picea mariana (Mill.) B.S.P.) has historically self-replaced following wildfire, but recent evidence suggests that this is changing.
