Summary 1.
Viggers & Hearn (2005) examined the encroachment of native herbivores on to farmland.
They presented kangaroo home range estimates and pasture biomass data for
three sites in south-eastern Australia, then made broad management recommendations
regarding the preservation of remnant habitat.
2.
While Viggers & Hearn identified potentially important patterns, we believe that
their data were neither sufficient nor appropriate to reveal the processes that underlie
these patterns.
3.
Specifically, their study was unreplicated at the land-use level, used inappropriate
density estimates for their study populations, failed to measure resources adequately,
used flawed methods of home range analysis, and demonstrated limited understanding
of key concepts and of their study species and thus could not draw valid conclusions.
4.
Synthesis and applications.
In view of these fundamental problems, we recommend
that decisions on the management of kangaroos
