When a buffer zone around the edge of the warren was added, to encompass any potential effects of underground structures extending beyond the disturbance visible at the surface, the difference between the mean NDVI values of warrens and control plots remained significant for Faure ( t 11270 = −7.05, p < 0.001) and Yookamurra ( t 62060 = 9.73, p < 0.001) but became marginally nonsignificant at Matuwa.
