Datasets of productivity and vegetation composition of boreal stands from an experimental design comparing silviculture scenarios of increasing intensity after 20 years

Vegetation surveys were conducted in July 2009 in humid boreal stands from an experimental design comparing silviculture scenarios of increasing intensity: (i) careful logging around advance growth (CLAAG); (ii) CLAAG followed by pre-commercial thinning; (iii) plantation followed by mechanical release of crop trees using motor-manual brushsaws; and (iv) plantation followed by chemical release of crop trees using herbicide and within five naturally disturbed sites. The surveys comprise data about the density of snags and of living trees (defined as having a diameter at breast height (1.3 m), DBH ≥ 1.1 cm), dendrometric measurements (DBH, height and basal area) of conifer and deciduous species, percent cover of trees and high regeneration (defined as having a height ≥ 60 cm and a DBH &lt; 1cm), shrub (defined as having a height &lt; 60 cm), herbaceous species and various taxonomic groups (ferns, mosses, sphagnum, lichens, grasses and <i>Lycopodium L.</i>). Data of the ratio of intercepted light to full sunlight conditions averaged by plot, derived from Photosynthetic photon flux density (PPFD) readings, are also provided.<br>This dataset covers raw and analised data. The metadata and the process of cleaning data and calculation are provided in DataInBrief_CleaningData.Rmd.<br>More details in:Urli M., Thiffault N. and Chalifour D.
