Herbicides were tested on 16 common shrubs and weed trees during the past 24 years. The woody plants included snowbrush ceanothus, deerbrush ceanothus, mountain whitethorn, varnishleaf ceanothus, sprouting and nonsprouting forms of greenleaf manzanita, hairy manzanita, hoary manzanita, golden chinkapin, golden evergreenchinkapin, Saskatoon serviceberry, Pacific madrone, salmonberry, western thimbleberry, scrub tanoak, and canyon live oak. Chemicals tested included 2,4-D, dichlorprop, 2,4,5-T, silvex, 2,4-DB, amitrole, amitrole-T, 2,3,6-TBA, AMS, picloram, KreniteTM, triclopyr, and an experimental carbamate compound. Low volatile esters of 2,4-D and 2,4,5-T proved the most effective and versatile herbicides for silvicultural use in western Oregon. Results of the screening tests are related to comparable data from small plot tests and project-scale aerial spray trials. To aid silviculturists, useful treatments and the most effective herbicide are shown in bold-face type for each shrub and weed tree.
The current trend toward the establishment and care of forests for a wide combination of uses requires flexibility in forest culture and a knowledge of the silvicultural choices available to the resource manager. This publication summarizes for each of 37 major forest types in the United States the silvicultural systems that appear biologically feasible on the basis of present knowledge. Supporting information is given on the occurrence of the 37 forest types, the cultural requirements of the component species, and the biological factors that control the choice of silvicultural options. The text is arranged in regional sections suitable for reprinting.
