White spruce enrichment planting in boreal mixedwoods as influenced by localized site preparation: 11-year update

The Forestry Chronicle, 2020
Ecosystem-based management aims to maintain the natural proportion of native species over a given landscape. White spruce (Picea glauca (Moench) Voss) is a species sensitive to environmental conditions; it is especially demanding in terms of nutrients ...

Marcell Experimental Forest Black Spruce Dendrochronology

, 2011
This data set includes raw tree ring width files of black spruce trees collected from six peatlands at the Marcell Experimental Forest. The data were collected for the purpose of investigating the roles of peatland water table elevations on black spruce ...

Estimation of arboreal lichen biomass available to woodland caribou in Hudson Bay lowland black spruce sites

Rangifer, 2003
An arboreal lichen index to be utilized in assessing woodland caribou habitat throughout northeastern Ontario was developed. The "index" was comprised of 5 classes, which differentiated arboreal lichen biomass on black spruce trees, ranging from maximal ...

Climate-growth relationships at different stem heights in silver fir and Norway spruce [PDF]

, 2012
We investigated the effect of climate on variations in annual ring-area increment along the stem of dominant silver fir (Abies alba Mill.) and Norway spruce (Picea abies (L.) Karst.) trees in the Black Forest, southwestern Germany, to test the hypothesis

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...
