The goal of this work is to evaluate site preparation treatments and planting as tools for forest rehabilitation in the context of global climate change. We propose planting red spruce (Picea rubens) seedlings on 12 ha of a 16 ha of mixedwood forest. The site was harvested under previous ownership with the assumption natural regeneration would repopulate the area. However, trails within the stand are experiencing regeneration failure. We want to explore reforestation as a tool for climate change mitigation, specifically by increasing carbon sequestration and storage potential.
