new mine complex on a bare, desert like piece of ground located along the south-west urban fringes of Broken Hill. The company engaged the honorary services of Albert Morris to advise on the establishment of tree plantations adjacent to the proposed new mining, office and residential complex, to protect the complex from sand-drifts and the strong local westerly winds. Construction of these tree plantations, which were to be irrigated with waste water and established by traditional planting methods, but using indigenous Australian vegetation including saltbushes, a method Morris had experimented with, commenced in May, 1936. The initial fencing of the main tree plantation site facilitated rapid and substantial natural regeneration within the still unplanted, and otherwise bare, fenced enclosure, of native grasses and forbs germinating from seed naturally stored in the soil. Crucially, this regrowth of indigenous vegetation persisted, as a result of foraging livestock and rabbits having been excluded by the new fencing. The knowledgeable Albert Morris had fully anticipated and predicted the natural regeneration that occurred within the fenced tree plantations adjacent to the new mining complex. As mentioned, he had already observed and confirmed this process in previous broad acreage field trials, and was aware of the ways in which arid-zone indigenous flora seed could be naturally dispersed by wind and stored in the soil, germinate, and thrive after relatively small amounts of rainfall. Although at this time natural regeneration of many indigenous flora species, such as Eucalyptus spp. (often referred to as gum trees), was a familiar concept to many settler Australians, Morris's knowledge of the viability of various arid plant species' seed, and his experience with the natural regeneration capabilities of the indigenous flora communities, were exceptional. Morris seized on this significant (approx. 22 acres; 9 hectares) demonstration of natural regeneration principles, and convinced the Zinc Corporation mine manager, A J Keast, to obtain the backing of senior Zinc Corp executive, W S Robinson, and other mining companies in Broken Hill, to undertake a new, separate project, the trial fencing of regeneration reserves to the south-west of the city. Morris intended that these reserves would primarily utilise natural regeneration, and limited, targeted amounts of planting, as their primary means of revegetation. Broken Hill regeneration area 1936-58 Work on the Zinc Corporation mining complex tree plantations continued, but Morris, also in an honorary capacity, was now additionally advising on the new Broken Hill regeneration area project,
