Tree Kangaroo and Echidna: Radio telemetry studies

Tree KangarooRooted in scientific research, the Tree Kangaroo Conservation Program’s work with tree kangaroos and related studies has sparked international interest in the region and has been the primary force in launching efforts to establish a Wildlife Management Area (WMA) on the Huon Peninsula in Papua, New Guinea. The Huon Peninsula is biologically unique, with habitats ranging from coral reefs to montane rainforests to sub-alpine grasslands. The TKCP's 80,000 acre conservation area is the first formal conservation area on the Huon Peninsula and the protected area now extends to the coast. The ultimate goal of the TKCP is the establishment of a 150,000 acre Wildlife Management Area that will extend from sea level to 4,000 meter mountains ranges.

In 2003 the TKCP, working with local landowners, established a new field site called Wasaunon. This new field site will serve as a base for research on the ecologies and home range sizes of both the Matschie’s tree kangaroo and the long-beaked echidna using radio telemetry. Wasaunon is extremely significant because it has not been hunted for a generation and there is evidence both species thrive in this area of high-altitude rainforest and grasslands. TKCP field scientists first assessed the site in 2003. In November of 2003 a month long effort to search for tree kangaroos and long-beaked echidnas and document locations was undertaken. Five wild tree kangaroos were observed. In March of 2004 three female tree kangaroos were successfully captured and fitted with radio transmitters. The data collected will be analyzed this fall but already patterns of movement have been observed. Individual females even showed preferences for certain trees within their range.

In March 2005 Christine McKnight, Topics Zookeeper, will be joining the TKCP field team to radio collar additional animals. The goal will be to fit five individuals, hopefully of both sexes, with radio transmitters. Dr. Lisa Dabek, project director, said she would like to see the TKCP become a model for utilizing keepers in field research. Christine will be the first keeper from an AZA institution to participate in the TKCP’s field research.
