On 13 March 2011, George Wilson of Australian Wildlife Services volunteered with ACT Parks and Wildlife to collect GPS tracking collars from Kangaroos around ACT Parks. Eastern grey kangaroos have been fitted with GPS tracking collars to assess their home range and movement throughout ACT’s urban parks. Twelve of these collars were programmed to fall off the kangaroos on March 13. A radio tracking receiver was used to find collar signals. The receivers are able to pick up collar direction and proximity to help the volunteers locate the collars. For more information visit the TAMS website.
