Session one of the Scaling Up Seed Supply webinar series presented by the National Tree Seed Centre. This session focuses on the equipment needed to collect, clean, and store tree and shrub seeds...
This webinar presented by the National Tree Seed Centre focuses on tree and shrub species that produce seed in the autumn and how to predict if they will produce a good seed crop. Species discussed...
This webinar presented by the National Tree Seed Centre explains how to collect seeds from berry producing plants species. NTSC staff demonstrate protocols for handling and processing berries to...
This webinar presented by the National Tree Seed Centre focuses on tree and shrub species at risk and how to properly and effectively collect and store their seeds for maximum reforestation potential...
This webinar presented by the National Tree Seed Centre teaches the skills and practices needed for collecting seeds from tree species which produce seeds in the spring. NTSC staff discuss maples...
Canada’s forests endure natural disturbances annually, contributing to the overall health and structure of the forest. In central Canada, the boreal forest is affected annually by both wildfires and...
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...
Delineating relevant local populations of widely distributed species is a common challenge in conservation ecology. Caribou and reindeer ( Rangifer tarandus) are in general decline throughout their...
The New Brunswick Gene Conservation Working Group was formed in 1997. The goal of the group is to develop gene conservation strategies for native New Brunswick trees and shrubs. The first step in...
The forest floor of boreal forest stores large amounts of organic C that may react to a warming climate and increased N deposition. It is therefore crucial to assess the impact of these factors on the...
This project describes a new method for sampling secondary structure in beetle-attacked pine stands and reports on a test of its accuracy. The method consists of interpreting aerial photos taken when...
Oak wilt is a tree disease caused by the fungus Bretziella fagacearum. The fungus is widespread throughout the eastern United States and, as of 2021, found within 600 m of the Canadian border near...
This pamphlet is about old-growth forests in Canada. It includes a map that shows the Forest Regions of Canada and provides examples of different old-growth forest types in some of these regions.
We reviewed recent literature to identify the positive and negative effects of thinning on both stand- and treelevel resistance and resilience to four stressors that are expected to increase in...
Can seedlings intended for reforestation be planted anywhere, regardless of the seed source from which they were obtained? The Optisource software was developed to help forest managers answer this...
Three experimental forest drainage sites were established in Alberta’s boreal forest to determine the effects of lowered water tables on soils, local hydrology, ground vegetation composition and tree...
Rapid, ongoing permafrost thaw of peatlands in the discontinuous permafrost zone is exposing a globally significant store of soil carbon (C) to microbial processes. Mineralization and release of this...
Since 1918, forest researchers have used the Petawawa Research Forest to establish long term experiments and have collected data using varied and innovative techniques to learn how trees grow within...
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural and semi-natural Canadian vegetation. The classification is a hierarchical taxonomy, describing...
