APPENDIX 287 



4. The Western Pine Association of Portland, Oregon, under which was 



included the Western Pine Division. This Division was the most widely 

 diversified, because it had to do with rules of forest practice on all the 

 Rocky Mountain and Pacific Coast States where ponderosa pine grows. 

 There were 7 districts, designated as follows: 



(a) Montana. 



(6) Idaho. 



(c) Washington. 



(oO Oregon. 



(e) California. 



(/) Arizona-New Mexico. 



(g) Rocky Mountains. 



The last included Engelmann spruce, lodgepole pine, ponderosa pine 

 and Douglas fir types, whereas the other districts were predominately of 

 ponderosa pine, except in the Idaho district where in the northern part 

 of the state, Idaho white pine type is the most valuable. 



5. The Hardwood Manufacturers Institute of Memphis, Tennessee, including 



the Appalachian and Southern Hardwood Subdivisions. 



6. The Southern Cypress Manufacturers Association of Jacksonville, Florida, 



including the Cypress Division. 



7. The North Central Hardwood Association of Indianapolis, Indiana, which 



included the North Central Hardwood Subdivision. 



8. The West Coast Lumbermen's Association of Seattle, Washington, which 



included the West Coast Logging and Lumber Division. 



9. The Southern Pine Manufacturers Association of New Orleans, Louisiana, 



which included the Southern Pine Division. 



10. The Northern Pine Manufacturers Association of Minneapolis, Minnesota, 

 which included the Northern Pine Division. 



Details of the rules of forest practice were formulated for each of these divi- 

 sions by its respective conservation agency. For example, in order to insure 

 forest lands being kept continuously productive in the southern pine region, it 

 was specified that 100 trees of 4 to 7 inches in diameter 12 inches above the 

 ground or 10 trees 8 to 11 inches in diameter, or 2 trees 12 inches or larger or 

 equivalent combinations must be left by the operator per acre as a minimum. 

 In longleaf pine forests, the minimum individual to be left was a tree 5 feet or 

 more in height, and 4 trees per acre were required in the 12-inch or larger class. 

 In all the Divisions, in order to promote development of sustained yield forest 

 management as permanent operating policy, all persons who were certified by 

 their division agencies as obtaining their raw materials from lands under their 

 ownership or control that were managed on a sustained yield basis were awarded 

 an additional production allotment of 10% under Article VIII of the lumber 

 code. 



As indicated above, the Rules of Forest Practice varied considerably with 

 each region and had to do with fire protection during and immediately following 

 logging, cooperation and protection against fire, insects, and disease, the conser- 

 vation of immature trees and young growth during and subsequent to logging, 

 and provision for restocking the land after cutting through selective logging, 

 planting, or other measures.
