A prairie was restored after heavy grazing stopped (Year 0). Scientists measured native plant species richness and the percent cover of bare ground.
Data:
- Year 0: Native species = 11; Bare ground = 55%
- Year 2: Native species = 18; Bare ground = 38%
- Year 5: Native species = 26; Bare ground = 22%
- Year 10: Native species = 29; Bare ground = 20%
- Reference prairie (never heavily grazed): Native species = 31; Bare ground = 18%
Which statement best describes the restoration outcome by Year 10 compared with the reference prairie?
