Table 1. An example of an alternative matrix to evaluate the affects of various 

 environmental and management activities on the survival of anadromous salmonids. 

 This matrix follows the methodology discussed in the previous text.

The previous matrix example only considers three sources of biological impact. The 

 analysis will become increasingly complex as the number of impacts being evaluated 

 increases. In addition, the ne^ to generate a separate matrix for each species and 

 basin (or aggregation of similar basins) combination requires that a considerable 

 amount of survival data be available for an accurate evaluation of the factors. 

 Unfortunately, much of the necessary data is currently lacking for most species and 

 basin combinations. 



CONCLUSIONS 



The Oregon Department of Fish and Wildlife has concluded that this report does not 

 provide an adequate scientific analysis or justification to support the conclusions 

 concerning the relative contribution of environmental and management factors to the 

 decline of Oregon's anadromous salmonids.
