Page 86, 2.2.3. Forestry 



General Comments 



This section provides an incomplete review of the available scientific information 

 concerning the relationship between forest management and salmonid habitat 

 productivity. The report does not adequately present existing information on several 

 subjects (large woody debris and water temperature), attributes forestry-related studies 

 and impacts to other land management activities (roads and riparian vegetation 

 removal) and does not present the results of several important long-term studies of the 

 affects of forest management on salmonid habitat and salmonid productivity. 



The importance of large woody debris for salmonid habitat, and the relationship that 

 riparian conifer harvest contributes to the shortage of this material is not adequately 

 presented. For a comprehensive literature review, the report should include 

 information contained within: Naiman et al. 1992; Bisson et al. 1992; Bisson et al. 

 1987; Bilby and Ward 1989; Bilby 1981; Robison and Beschta 1990; Bustard and 

 Narver 1975; McMahon and Hartman 1989; Heifetz et al. 1986; Nickelson et al. 1992; 

 Andrus et al. 1988; Ursitti 1990; and many others. 



The relationship between riparian vegetation removal, water temperature and the 

 productivity of salmonids is not presented in adequate detail. For a comprehensive 

 literature review, the report should include the results of such studies as: Holtby 1988; 

 Beschta et al. 1987; Brown et al. 1971; Duston et al. 1991; Li et al. (in process); 

 Ringler and Hall 1975; and many others. 



The results from long-term studies of forest management and salmonid habitat are not 

 presented in the report. For example, the results from studies such as the Alsea 

 Watershed Study (Moring 1975a, 1975b; Moring and Lantz 1975) and the Carnation 

 Creek Study (Hartman and Scrivener 1990; Holtby 1988) should be included in the 

 report for the document to be comprehensive. 



Woody Debris Removal (page 88): 



The report presents a significant discussion of past debris removal activities by fisheries 

 agencies, but does not investigate the role of riparian conifer harvest on the long-term 

 supply of large woody debris. The current shortage of this material is primarily 

 attributed by the authors to debris removal activities, but research exists that also 

 discusses the relevance of these shortages to timber harvest. In addition, the report 

 does not acknowledge that typical debris removal projects involved log jams consisting 

 of hundreds of logs that totally obliterated sections of streams.
