Author: Worthington, Norman P.;

Publication Series: Scientific Journal (JRNL)

Description: Test plantings have been made on the Hemlock Experimental Forest in cooperation with the St. Regis Paper Company to test suitability of several native conifers for planting on heavy bracken and brush-covered Site II areas typical of the western Olympic Peninsula. In the spring of 1950, 2,500 Douglas-fir seedlings from the Forest Industries Tree Nursery at Nisqually were planted. In 1952, planting was continued with 1,000 Sitka spruce, 500 grand fir, and 1,000 western redcedar from the U. S. Forest Service Nursery at Wind River, and in 1953 with 2,500 western hemlock, a gift of the British Columbia Forest Service. Spacing was 6 x 6 feet for all species except hemlock, which was spaced 4 x 4 feet. The latest remeasurement of the plantations was made on January 26 and 27, 1955. Species suitability is rated according to:

1. Survival
2. Height growth
3. Immunity to animal damage
