Agriculture (page 176): 



Again, according to the most recent data available from the U.S. Dq)artment of 

 Commerce (1987 Census of Agriculture 1:37 Oregon State and County Data), there 

 were 17.8 million acres of farmland in Or^on, not 28 million as stated here. Perhaps 

 the difference here may be attributed to government grazing land leased on a per-head 

 basis that is excluded from the Department of Commerce total, or perhaps the reference 

 is to 2.8 million acres of harvested cropland. Who knows?

Climate and C atastrophes fP. 180-181): 



'Storms of equal intensity will cause twice the erosion on agricultural 

 lands as on forested lands (Sedell and Beschta 1991). ' 



As discussed previously, the source cited by the authors does not substantiate this 

 statement. The contention that the research presented by Sedell and Beschta (1991) 

 supports a differentiation between erosion rates on agricultural and manjiged forest 

 lands appears to be a misinterpretation or misrepresentation of the scientific study by 

 Hickin (1984). 



Ocean Productivity C?. 181-182): 



There is no discussion of the effects of temperature in non-El Nifio years {See 

 Nickelson 1986). 



"...as ocean conditions changed with the development of the 1982-1983 

 El Nino. " 



The most recent series of years with poor ocean conditions actually began in 1976, 

 upwelling was weak and a warming trend was apparent, well before the 1982-83 El 

 Nino (McLain 1984; Nickelson 1986). 



'There is a suggestion that native coastal coho salmon had more of a 

 north-migrating tendency in the past than hatchery coho salmon, and 

 were less affected by El Nino. . . ' 



The statement is not supported by the data presented in Fig. 1. 1-8, attributed to 

 McKeman et al. (1950). The effects of the 1941 El Nifto are evident on the 1942 catch 

 in all rivers. 



Natural Predation (p. 182): 



Lack of stream complexity resulting from l(^ing activities, especially log transport, 

 probably contributes greaUy to predation in nvshwater.
