Figure 8.9 Nitrate concentration and land value (US dollars) relationships to mountainside development.
Mountainside development was quantified as the percentage of developed land-cover area that was also in the upper
60% of the catchment altitude. Linear regression lines and coefficient of determination are shown in the figures. Data
for Franklin and Rabbit Creek were not used in the regression shown in the lower panel.

et al ., 2001). Other studies have shown little
difference between using catchment and riparian
land-cover (Johnson et al ., 1997; Dodds and Oakes,
2008) for predicting stream responses. Most studies

comparing land cover and stream chemistry have
been conducted in areas of little topographic relief
that are dominated by agriculture (Osborne and
