The temporary sample plot is a circular sample unit that covers an area of 400 m2 (the main unit). For each tree, we observe and measure the species, diameter, and stage in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In addition, the age and height of three trees are determined. Finally, a survey of the station is carried out. Plot data also includes information about the location of the plots and the sampling plan. These data are acquired as part of the second forest inventory in southern Quebec. They were used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forests in Quebec. The establishment of these plots took place between 1980 and 1993. This database covers almost all of the territory south of the 52nd parallel of Quebec's public and private forest.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

__The link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. The forest maps in the second inventory are available at a scale of 1/20,000. They cover almost all of the territory south of the 52nd parallel. Each file covers an area of approximately 250 km2. These digital cards correspond to the black and white paper cards with a dimension of 125 cm X 75 cm that have been scanned. They illustrate forest stands. They were prepared from the photo-interpretation of aerial photos on a scale of 1/15,000.
