Figures & data
Table 1. Eleven native aquatic plant species were transplanted into units with and without herbivore protection to evaluate their suitability for replacing hydrilla being controlled by triploid grass carp.
Figure 1. Vegetation cover class coverage (mean + SD) between 4 grass carp densities (C = control, LD = low density, MD = medium density, HD = high density) before (2010) and after (2011) stocking grass carp; denoted with letters are statistically similar groupings (α = 0.1) of main effects year (upper-case) and grass carp density (lower-case), where appropriate (least significant difference).
Table 2. Results of the probit regression for vegetation community structure class percent coverage response to grass carp densities over time; significance is given in bold.
Table 3. Results of the probit regression for planted vegetation cover class percent coverage response to grass carp densities over time; significance in bold.
Table 4. Raw and percent planted vegetation coverage (mean ± SD) between 4 grass carp densities (C = control, LD = low density, MD = medium density, HD = high density).
