Sampling Techniques to Detect Canopy Infestations of the Hemlock Woolly Adelgid
Resource
Hemlock woolly adelgid ( Adelges tsugae Annand) has recently invaded Canada and is threatening the survival of eastern hemlock. An important part of the management of the hemlock woolly adelgid is...
Save Our Species: A Blueprint for Restoring Butternut (Juglans cinerea) across Eastern North America
Resource
Butternut is a relatively uncommon hardwood tree native to eastern North America. The species’ abundance has declined over the past 50 years, primarily because of an invasive pathogen ( Ophiognomonia...
Seed Shelters Improve Black Spruce Establishment and Survival on Upland Cutovers
Resource
This note presents fifth-year stocking, density, and height growth results for three lowland and three upland seed spot experiments that compare untreated/unsheltered black spruce seed spots with...
Seedwhere: A Computer Tool for Tree Planting and Ecological Restoration
Resource
It is generally recognized that plants are genetically adapted to the prevailing climate. Planting stock is often moved across environmental gradients with little knowledge of the ecological risks...
Short Rotation Woody Crop
Resource
Providing the knowledge needed to mitigate climate change effects and improve forest management, this long-term research by the CWFC could expand the circular bio-economy through high-yield crops that...
Silvicultural Treatments for Black Spruce Establishment in Boreal Ontario: Effects of Weed Control, Stock Type, and Planting Season
Resource
Four field experiments were carried out to assess the performance of black spruce ( Picea mariana [Mill.] B.S.P.) outplants in relation to: weed control (i.e., with vs. without), stock type (i.e...
Site Restoration. Step 1: Looking Back to the Past
Resource
Because natural resources development causes landscape disturbance, post-development site restoration requires an in-depth knowledge of previous conditions. What did the landscape look like before...
Size Requirements of Intact Forest Landscapes for Effective Biodiversity Conservation under Regional Fire Regimes and Climate Change
Resource
Conserving large intact forest landscapes (IFLs) is one forest management strategy to mitigate industrial impacts on the environment. Measuring the IFL inventory at national scales has also been...
Sizing Canada’s National Seed Supply Chain: Preliminary Assessment focused on Trees and Shrubs
Resource
In 2021-2022, the National Tree Seed Centre led a series of surveys to establish an accurate idea of genetically appropriate seed supply for forest landscape restoration (FLR) needs across Canada by...
Snow-caching: On-Site Interim Storage of Planting Stock
Resource
This technical note summarizes the feasibility of on-site interim storage of bare root black spruce tree seedlings, details snow-cache construction, and notes the costs and savings associated with the...
Soil Displacement and Compaction Effects on Conifer Seedlings in Southeast British Columbia: Study Establishment
Resource
Soil disturbance from forest harvesting has been shown to compromise site productivity. We established satellite trials in five of the Long-Term Soil Productivity (LTSP) sites in southeast British...
Soil Properties and Root Development in Forest Trees: A Review
Resource
The literature is reviewed with the aim of consolidating silviculturally important information about interactions between root system development and soil properties; a complementary objective is to...
Source of Growth Variability in Interior Douglas-fir
Resource
To assess the growth of the uneven-aged stands of Douglas-fir in the Interior Douglas-fir zone of British Columbia, and the factors influencing the growth, data from 92 permanent sample plots were...
Southern Vancouverian Dry Foothill Forest & Woodland
Resource
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural and semi-natural Canadian vegetation. The classification is a hierarchical taxonomy, describing...
Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
Spongy Moth
Resource
Spongy moth ( Lymantria dispar) is a naturalized non-native pest that prefers oak leaves, but it can defoliate several other tree species native to Canada. Repeated high rates of defoliation by spongy...
Stand Development After Partial Cutting of Mature Mixed Stands of White Spruce and Aspen in Manitoba
Resource
One-hundred-year-old mixed white spruce–aspen stands were partially cut in 1953, 1954, and 1955 and scarified leaving treatments that retained 14–100% of total stand basal area. Composition of the...
Stem Rusts of Pine
Resource
Forest Pest Leaflets are a series of about eighty publications dealing with insects, tree diseases, and other problems affecting the growth, survival, and general health of forests. Each leaflet...
Successful Tree Planting
Resource
This maintenance schedule outlines the care that trees need in each season. It can be used as a checklist year after year. You can adapt it to your local area and the specific needs of your project.
