Book Description
Begins with a literature review on the habitat, reproduction and establishment, and stand development of black spruce. This is followed by a review of thinning as a silvicultural system, and thinning of black spruce in particular. Concludes with a report of a case study of the growth response of black spruce to various levels of thinning. The study area had been burned by wildfire and is located in the Tyrol Lake Demonstration Forest near Lake Nipigon, Ontario.

Book Description
The growth of black spruce (Picea mariana (Mill.) BSP) and tamarack (Larix laricina (Du Roi) K. Koch) on two drained peatlands, at McLennan and Wolf Creek in central Alberta, was greater than on undrained control areas 910 years after drainage. On the drained plots, diameter growth was 1.62.3 times, height growth 2.73.5 times, and volume growth 4.49.7 times that on the undrained control plots. There were no clear differences in growth among various ditch spacings (30, 40, 50, and 60 m), and correlation between tree growth and distance of trees from the nearest ditch was poor. These results suggest that drawdown of the water table was sufficient to create unsaturated zones that facilitated equitable tree growth across the strips between ditches. Tree ring analyses revealed that increases in growth could begin as early as 34 years after drainage. The successful regeneration of black spruce on the control plots at McLennan and the reasonable size of black spruce and tamarack ingrowth on control plots suggest that both species are able to germinate and survive on wet sites initially, but high water tables inhibit their further development. Additional periodic measurements of both species are necessary to determine long-term growth patterns after drainage and to assess the financial feasibility of peatland drainage as a practical option in forest management.
