Changes in methodology were instituted in 1993 that increase 

 demographic monitoring accuracy. It is suggested that the 

 relative demographic profile of the populations over time can be 

 roughly compared between years though the original circular plots 

 do not encompass the same individuals as the belt transects. 



Demographic profiles are secondary at this point to determining 

 rates of life history stage transitions. The data from 1993, 

 summarized below and detailed in Appendices X-X, will provide 

 the basis for stage-based population matrix modelling through at 

 least 1995.

This monitoring was not established for determining population 

 trends or developing population viability analysis. If the 

 population segments in the Russian Creek and Neihart continue to 

 drop, then further expansions in study design to monitor the 

 latter may be appropriate.
