Tables 1 and 2 (192k)
Table 1: Description of riparian restoration units on the Sacramento River where soil
cores were sampled and vegetation response was studies. RM stands for river
mile, and L and R refer to left and right bank (looking downstream) respectively.
Table 2. Partial list of physical and biotic parameters that should be assessed (independent
variables that may be used in statistical analyses and modeling). Landscape parameters
can be calculated for study sites from GIS coverages.
