Figures & data
Table 1. Treatments and distribution of damage assessment transects, and trapping and removal of wild pigs (n = 356) across three study sites (Coffey Ranch, Hoffmann Ranch, and Oswalt Road Ranch) in south-central Oklahoma, USA, from 2010 to 2011. Treatments consisted of non-trapped units, corral traps, and drop nets. Corresponding damage surveys for wild pig rooting activity were conducted from 2009 through 2011
Figure 1. Trends in rooting damage by wild pigs along transects (m2/transect) across five time periods from 2009 through 2011 in south-central Oklahoma, USA. Period 1 = pre-trapping; periods 2, 3, and 4 = trapping; and period 5 = post-trapping. Back-transformed means and 95% CI are reported.
Figure 2. Temporal trends in damage reduction (area; m2) within each treatment (control, corral trap, and drop net) across five periods from 2009 through 2011 in south-central Oklahoma, USA. The interaction was not significant (p = 0.264) due to the model specification, but the patterns show that damage, despite being reduced because of spillover effects, was still greater in the control unit compared to the corral trap and drop net treatments.
