This is the key species-based abundance table, to be used for analysis. Index columns are year (1991-2006), treatment (c=control, i=irrigated), elevation (l=lower, u=upper), transect (1 or 2 for each treatment), and plot (1-31, non-continuous). Remember that we have two transects per treatment; T1 is plots 1-15 (1-5 are lower, 10-15 are upper) and T2 is plots 16-31 (16-20 are lower, 27-31 are upper). No T2 data for 1991 and 1992 and we are not dealing with the mid-slope plots.
