This data package contains crop tree, overstory, sapling, and regeneration data collected between 2008 and 2012 as part of the project titled 'Rehabilitation of cutover mixedwood stands: An economic and silvicultural assessment of alternatives' as described in Appendix C of FS-NRS-07-08-01 'Silvicultural effects on composition, structure and growth of northern conifers in the Acadian Forest Region 2008 study plan' (also known as the Compartment Management Study, see Kenefic et al. 2015). While the Rehabilitation study was conducted within two management units of the Compartment Management Study (CMS) the data for the Rehabilitation study are independent of the CMS. The Rehabilitation study examined two levels of intervention treatments against controls in two stands that had been subjected to repeated commercial clearcutting harvests, last occurring 20 and 25 years before. The intervention treatments were 1) moderate treatment, in which crop trees were identified and released, and 2) intensive treatment, in which crop trees were released, unacceptable growing stock was removed, and fill planting of red spruce was conducted. Data are available in seven data sets: 1) crop tree stem map; 2) crop tree DBH (diameter at breast height) and mortality; 3) crop tree heights; 4) overstory DClass (diameter at breast height class); 5) sapling DClass; 6) regeneration tally; and 7) overstory plot locations.
