The temporary sample plot is a circular sample unit that covers an area of 400 m2. For each tree, we observe and measure the species, diameter, sunlight, and floor 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 and the vegetation of the undergrowth is carried out, and the characteristics of the soil are noted. Plot data also includes information about the location of the plots and the sampling plan. These data are acquired as part of the fourth ecoforest inventory in southern Quebec. They are used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forests in Quebec. They can also be useful in the development of private forests. The establishment of these plots took place from 2004 and will be completed in 2018. 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 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.

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. The **Station Quality Index (PQS) plot ** is the sampling unit that made it possible to characterize the productivity of stations in the Quebec forest ecological classification system. These are circular plots where the physical and vegetation characteristics of the station have been recorded. Thus, the stems were counted, and the ecological type of the station was determined. In each plot, about ten study trees were selected, felled and cut at several heights along the trunk. A total of **1,644** plots were installed, and **12,215** plots were analyzed. The location of the plots was recorded using a GPS. This dataset covers most of the public forest in the territory of the ecoforest inventory of southern Quebec. __ ⚠️ Note that__ the sampling was carried out between 1999 and 2009, and the dataset will not be updated.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
