The introduction of invasive, non-native earthworms into forest ecosystems has increased as recreational, industrial, and commercial activities increase in northern Ontario. The presence of these ecosystem engineers in ...

The field of forestry has evolved to meet several objectives, including timber and other forest product production, tourism and recreation, habitat and wildlife management and climate change monitoring. As the field ...

Logging residues can retain important nutrients for tree growth after biomass harvesting. However, increasing the harvest intensity may decrease soil nutrient stores stocks and affect biomass productivity. Using 2207 ...

The boreal forest in Canada provides a large volume of timber for Canadians and other countries year after year and effective silviculture is the key to sustainable harvesting. Site preparation can be a critical step in ...

Climate change poses a big threat to boreal forest managers. We have set out to test how different precipitation levels will affect a number of boreal understory species across the three forest types commonly found in the ...

The purpose of this study is to assess the performance of black spruce seedlings at a genetic trial designed to select seed sources adapted to several climate change scenarios. Height variability among trees is attributed ...

Ground beetles (Coleoptera: Carabidae) are a useful bioindicator group in forests in almost every part of the world. This thesis studied the biodiversity of carabid beetles in old and young age trembling aspen (Populus ...

Effective renewal of harvested stands in Ontario is mandated in the Crown Forest Sustainability Act (CFSA 1994). Properly prescribed silviculture leads to forested stands that are regenerated successfully, have predictable ...

1. Fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. Species diversity loss has been recognized as one of the primary global change drivers that can have profound negative effects on ecosystem ...

Red pine is a historically important species for forestry in the boreal forest. Its large diameter and straight and knot free form has made it ideal for many purposes, including construction. With the new sudden turn towards ...
