Understory woody vegetation harvest impacts study NRCAN-CFS Understory woody vegetation was measured in approximately 200 5x5 m quadrats, associated with the harvest impacts study. Plots are located within different harvest treatment blocks and capture a variety of post-harvest canopy opening and soil disturbance combinations resulting from selection, shelterwood, and clearcut harvest operations. Data were collected in 2000, 2006, 2010, 2014 and 2019 and focused on the density and size of tree and shrub species > 0.3 m tall.

Data is available through collaborative projects. Contact Stephanie.Nelson@canada.ca.
Soil NRCAN-CFS Soil properties from four intensive study sites including one clearcut harvested and three unharvested sites.
