There has been an annual survey of Ground Parrots in this manner since
(I think) 1983 at Barren Grounds. GPs do continue to inhabit the
surveyed area. The information gained is valuable in managing reserves
containing GPs particularly regarding fire regime. I don't think the
people who organize the surveys would say there is definitely no impact
just that its small enough to be justified.
