DRAFT 



The discussion does not recognize the long-term changes in habitat productivity 

 that have resulted from forest management activities. 



(2) the importance of forest management activities to the long-term supply of 

 instream large woody debris is inadequately discussed. Current shortages of 

 this material are primarily attributed to past debris removal activities, but 

 pertinent research concerning the influence of timber harvest in riparian areas to 

 these shortages is not presented. 



(3) the affects of forest road construction on salmonid survival should be 

 presented in this section. Forest roads are a significant proportion of the total 

 road miles in Oregon. 



(4) the comparison of pesticide use in forestry and agriculture is not 

 scientifically valid because the data used to make these comparisons does not 

 include all forest lands. The original study reported pesticide use on US Forest 

 Service lands only, and did not include other federal, state or private forest 

 lands in the estimate. 



2.2.4. Municipal-Industrial 



This section is primarily a discussion of point source pollution discharges by municipal 

 and industrial entities without any empirical evaluation of the importance of these 

 factors to the decline of salmonids. In addition, the tabular information that is 

 presented to summarize these pollution problems is inaccurate. A table listing the 

 number of stream miles "adversely affected" by such parameters as low dissolved 

 oxygen, bacteria, turbidity, elevated temperatures, etc. is presented in a manner that 

 implies that municipal and industrial sources are the cause. However, the data in this 

 table actually reflects an assessment of statewide nonpoint pollution problems from a 

 multitude of land use activities. The report cited for this information (ODEQ 1990) 

 indicates that municipal and industrial sources are a minor component of the pollution 

 problems, and that the majority of stream miles affected are attributed to forestry and 

 agricultural practices. 



2.2.5. Mining 



This section is a historical discussion of mininjg in Oregon with very little information 

 presented concerning the effects of these activities on stream habitat or salmonid 

 productivity. The information presented is inadequate to derive any conclusions of the 

 relative importance of these activities to the decline of salmonids. 



This section is generally an accurate description of the variability that natural events 

 can exert on the survival and productivity of anadromous salmonids, and appropriately 

 notes that the magnitude of the effects of these events can be increased by land
