Forest Tree Improvement Research in the Forest Service

Tree improvement research in the Forest Service began about half a century ago, not long after the Forest Service was established and only about 10 years after Mendels papers on inheritance were rediscovered. This early work was concerned with racial differences within species, as an expression of adaptation to special environmental conditions. A study of seed sources of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) was started in 1912 by T. T. Munger (1936), who summarized the results in 1936 to show that racial differences did exist. Recently these old plots have been reexamined and the data are being summarized.
