Fig 3. The relationship of wetland prevalence index for 11 paired grazed and ungrazed riparian reaches in northeastern Oregon.

If there was no difference in the index between grazed and fenced areas the data points would be expected to fall on or near the line. Data points below the line indicates a greater abundance of wetland species in ungrazed areas compared to grazed reaches. There was a significance difference (p = 0.01) in the wetland indicator scores of grazed and ungrazed areas.
