Summary:

"A study was established to examine growth and yield of a range of PCT treatments in a mixed western hemlock (Tsuga heterophylla (Raf.) Sarg.) and amabilis fir (Abies amabilis Dougl. ex Forbes) stand that had regenerated naturally, and at 18 years was characteristically clumpy with density ranging from 0 to 80 000 stems per hectare (sph). Using the results from the 15-year post-treatment measurement, future growth and yield of each PCT treatment was projected, and a financial analysis was conducted to compare the costs and benefits of PCT or no treatment. As expected, the results of the financial analysis showed that the site values increased for all the PCT treatments and the control under the scenarios with lower discount rate, lower harvesting costs, and higher log prices."-- from publisher.
