Landscape
The Little Abitibi research area is relatively flat with numerous wetlands scattered throughout. The forest is a mix of boreal coniferous species, dominated by black spruce. The surficial geology is either ground moraine or lacustrine deposits depending on the location within the research area. Soils are predominately silt or clay loam luvisols, although brunisol mantle kames and eskers are also found in the region. The research area is divided into two bedrock types: granitoid or tonalite intrusive rocks. Muliple disturbance types and regimes have affected the forest over the last few decades including: timber harvesting, fire and infestation. Streamflow is snowmelt dominated.
