mining industry and Broken Hill Council. The Barrier Field Naturalists Club also continued its involvement with the reserves, with members conducting botanical surveys of the thriving natural flora and advocating for the extension of the regeneration area. The Mine Managers Association of Broken Hill financed the upkeep of the regeneration reserves, and Broken Hill Council managed this work. The citizens of Broken Hill suffered severely from the effects of the 1940 drought, and further prolonged dry periods in the early to mid-1940s, as enormous dust storms ravaged the city. Due to the success and popularity of the regeneration reserves, from 1946 the city administration lobbied the New South Wales government to complete the encirclement of the city with further regeneration reserves. Three new reserves were fenced to the north and east of Broken Hill between 1950 and 1958, and natural regeneration of the indigenous vegetation occurred. The regeneration reserves created between 1936 and 1958 now primarily comprise the current Broken Hill regeneration area, with minor adjustments having been made over the years. Natural regeneration It has in the past, and still is very often mistakenly assumed, that planting techniques were predominantly utilised to initially establish the regeneration reserves, and that the regeneration area project was primarily an exercise in planting. It is correct that the Zinc Corporation tree plantations of 1936-37, quite separate and also small projects relative to the regeneration reserves, and located immediately adjacent to the urban area and piped water resources, were irrigated, and their vegetation established by the manual planting of thousands of trees, along with saltbushes; this was documented at the time. However it is clear from Albert Morris's interest in natural regeneration, as already outlined in this article, and the historical documentation, that the regeneration reserves, as distinct from the tree plantations, primarily and intentionally utilised principles of stock exclosure (fencing to exclude stock) and natural regeneration, and not planting, to achieve the revegetation, with indigenous flora, of the hitherto barren reserves. Albert Morris was interested in achieving broad acreage arid-zone revegetation outcomes, both for amenity and conservation purposes, and as he realised, it would have been impossible to achieve this, given the prevailing dry, hot and often drought stricken conditions, by utilising a planting technique. To propagate, manually plant and then keep hydrated until they were established the tens of thousands of trees, shrubs, grasses and forbs necessary for such a project, conducted
