distance variable reduced the final sample to 1,031. 



In order to estimate the TCM model, it was necesary to 

 identify an origin zone for each individual hunter. Separate 

 maps were developed for each hunting site, and counties and 

 states were aggregated in roughly concentric zones around the 

 site. The basic criteria used in zonal aggregation was to have 

 at least one observation per zone, to have the observation in a 

 given zone be in an approximate population-weighted average 

 location, and to have contiguous zones (no unaggregated areas) 

 out to the limits of the observed spatial market. Typically, 

 zones nearest a site were single counties, with aggregates of 

 counties defining the origin zone around more distant 

 observations. Nonresident origins were states or aggregates of 

 states . 



The 40 specific deer hunting areas originally defined for 

 this study were based on aggregations of the 129 hunting 

 districts shown in DFWP hunting regulations. These areas are 

 shown on the "Elk and Deer Hunting Areas" map in Appendix B. 

 Because of the sample size, a number of the aggregated hunting 

 areas only had a few observations. Hence, a number of hunting 

 areas were combined. The net result was that the original 40 

 areas were reduced to 21 aggregated hunting sites. 



In addition to the survey, two additional data sources were 

 used in developing the deer hunting data base. DFWP personnel in 

 each region were surveyed by John Cada , Assistant Research Bureau 

 Chief, to identify the predominant management, topographic, 

 reading, and timber characteristics of each site. The management 

 characteristics were based on the general type of hunting
