Plantation Productivity in the Douglas-Fir Region Under Intensive Silvicultural Practices: Results from Research and Operations

The full text article is temporarily unavailable.

We apologise for the inconvenience. Please try again later.

This article reviews major plantation silvicultural practices used in the westside Douglas-fir region of Oregon and Washington: origin, growth and yield impacts, and the region's global competitive status for productivity, tree-growing costs, and returns. Two main messages emerge: (1) there has been great progress in the region to increase wood yield and shorten rotations; and (2) opportunity remains strong for this region to become even more competitive, although it will require challenging current beliefs and norms and an increased collective will and focused sense of urgency.
