INTERNATIONAL PROVENANCE TEST OF REDWOOD (SEQUOIA SEMPERVIRENS) |
| In October 1983 Professor John Kuser, Dept. of Horticulture and Forestry, Cook College, Rutgers University, Box 231, New Brunswick, New Jersey, U.S.A.08903 and his associates, initiated a rangewide provenance test of Redwood, Sequoia sempervirens (D.Don.) Endl. The principle investigators, in addition to Dr. Kuser, are Prof. William Libby, Dept. of Forestry, University of California, Berkeley, CA, Mrs. Jeanne Martin, California Dept. of Forestry at Davis, CA, and Mr. James Rydelius, Simpson Timber Co., Arcata, CA. |
| Little is known about genecological variation in redwood. Accordingly, the objectives of the test are firstly, to assemble a collection of clones from some 90 locations covering the natural range of the species along a 720 km strip of the U.S. Pacific Coast and, secondly, to establish clonal replicate test plantations at key points in the natural range and in areas in the U.S. and overseas which are outside the natural range. |
| Results of the text, for which a detailed study plan has been prepared, would enable foresters and park managers within or outside the natural range of redwood to choose the most appropriate seed source for their conditions. |
| Sterilized cuttings from the assembled collection could be made available for shipment from early 1986, at a charge of approximately US$0.25 each to cooperators outside the U.S. |
| Individuals or organizations interested in collaborating in the test should write to Dr. Kuser direct. |
