I•°' 40 <br />Some useful information can be gleaned from this tabulation. <br />First of all, the sampling fractions for the three strata are low <br />and any extrapolations from the data should keep this in mind. <br />Second, it is obvious that the relative number of sites found in <br />each ecological zone differs significantly from what one would <br />expect to find if those sites were distributed proportionate to <br />the size of each ecological zone. In other words, a greater than <br />• expected number of sites are found in the Pinyon-Juniper, Oak <br />Brush zone, and the number of sites in the Ponderosa Pine-Douglas <br />Fir and Ponderosa Pine zones is fewer than expected. The <br />differences are large enough to allow us to conclude that they <br />are attributable to cultural choices, rather than random factors <br />or sampling errors. <br />we may use these survey data to estimate the total number of <br />prehistoric sites that might be found in the project area. <br />According to Figure 1 from Lutz and Hunt (1979), the project area <br />encompasses three ecological zones: Ponderosa Pine, Pinyon- <br />Juniper and oak Brush, and Loamy Foothills. Table 6 summarizes <br />our estimates of the number of prehistoric sites that may be <br />found in the project area and in each ecological zone. <br />Table 6.

First, the <br />total number of sites in the Lutz and Hunt (1979) survey area <br />! were estimated by dividing the number of sites found in each <br />ecological zone by the relative size of each zone. Thus, the <br />Ponderosa Pine-Douglas Fir zone is estimated to have 225 sites <br />(9 sites/4 percent), the Ponderosa Pine zone should have 1,125 <br />sites (45 sites/4 percent), and the Pinyon-Juniper & Oak Brush <br />zone has 5,643 sites (158 sites/2.8 percent). Next, these site <br />number estimates were divided by the total number of acres in <br />each zone for the large survey area and divided by the number of <br />acres in each zone in the permit revision area. Since the Loamy <br />Foothills zone was not sampled by the Lutz and Hunt (1979) <br />
