Abstract: The valleys of the Avoca and Harper Rivers have been used for sheep grazing for nearly 100 years. Red deer, chamois, rabbits, hares and opossums have been present for 40 to 100 years. The total number of wild plus domestic animals now clearly exceed the safe carrying capacity of the land, particularly in view of the use made of the water yield for power generation.
Animal control operations, underway or proposed, are outlined. Drift fences are to be erected for control of domestic stock and huts are to be built at strategic points to facilitate wild animal control. Pellet lines have been established and these will provide much required information relative to the seasonal movements of the various groups of animals and to the population densities of each from point to point. This information will permit the design of appropriate control measures and assessment of their effectiveness.
— Herd studies (deer and chamois) are also under way for determination of herd structure, range, productivity, behaviour, forage habits, etc., and it is thought that this work will produce facts applicable over a far greater extent of country.
