Translocation of threatened terrestrial orchids is increasingly seen as a viable ameliorative conservation option when habitat is destroyed or modified through changing land use. Most orchid translocations reported in the literature detail nursery-raised seedlings planted into intact and suitable habitat, and few involve translocation of entire plants and their mycorrhizal fungal associates. As part of a larger translocation study, soil cores containing 46 individuals of the threatened Painted Diuris (Diuris tricolor) were translocated into herbivore-proof plots on restored and rehabilitated post-mining lands in the Hunter Valley of New South Wales. After 3 years of annual flowering and fruiting, new recruits (mature flowering plants) were observed within translocation plots but outside of original soil cores, and at 6 years following translocation 29 new individuals were observed. Two of these individuals germinated outside of fenced plots. At peak flowering in 2020, a search of rehabilitated lands outside of translocation plots failed to locate any orchids, discounting the unlikely possibility that orchid tubers may have survived the process of topsoil stockpiling and respreading. Successful recruitment of Painted Diuris into mining rehabilitation has the potential to significantly offset any losses of this species resulting from mining operations within the region.

将受威胁的陆生兰花（Diuris tricolor）转移到新南威尔士州猎人谷的采矿恢复区后成功招募

当栖息地因土地利用的改变而遭到破坏或改变时，受威胁的陆生兰花的易地越来越被视为一种可行的改善性保护选择。文献中报道的大多数兰花易位都详细说明了苗圃培育的幼苗种植到完整和合适的栖息地，很少涉及整株植物及其菌根真菌关联物的易位。作为一项更大的易位研究的一部分，土壤核心包含 46 只受威胁的彩绘 Diuris ( Diuris tricolor) 被转移到新南威尔士州猎人谷恢复和修复的采矿后土地上的防食草地块。经过 3 年的一年开花和结果，在易位地块内但在原始土壤核心之外观察到新的新成员（成熟的开花植物），在易位后 6 年观察到 29 个新个体。其中两个人在围栏外发芽。在 2020 年开花高峰期，在易地地块外的恢复土地上的搜索未能找到任何兰花，因此排除了兰花块茎在表土储存和重新传播过程中幸存下来的可能性。
