Tribal Assessment |

The Cascade Range Region |
|
| Since we wanted to
statistically derive a correlation matrix for each region, we needed at
least four sites to in the correlation. There are ten sites within
the region. IMPROVE and IMPROVE
protocol sites used in this analysis are shown in this
map. |
|
| The details of the
correlation analysis are provided in tabular format below. The
Representative Distance (Rep. Dist.) is 107 km for this region.
Representative distances were based from exponential curve fits to the
correlation verses
distance curves. |
