Cuttings were collected from one plant at Ebony Point soon after the Dwarf Ebony was rediscovered in 1980, following a daring cliff descent on a rope and makeshift harness by Charlie Benjamin. In 2008, further collections were made from the second plant by Mike Thorsen. The species also grows well from seed, and has now been propagated very successfully. Today, there are a few thousand specimens on St Helena, mostly in gardens and at sites where attempts have been made to restore the species to wild situations. The main reintroduction sites include Ebony Plain (approximately 840 surviving plants), High Peak (130 plants) and the Millennium Forest (several hundred).
Unfortunately, the species' ecological requirements were little understood when the restoration efforts commenced, and problems have subsequently been noted in all situations. Habitats at Ebony Plain and the Millennium Forest are both very barren with dry soils, and although specimens have survived, flowered and seeded well in both cases, the natural recruitment has been close to zero. Conversely, High Peak was chosen as a humid, upland location, and here, the low canopies have been largely overgrown by vigorous invasive grasses. It is likely that the habitat requirements are rather specific, and suitable areas may now be limited following the extensive degradation of coastal hills and colonization of the higher elevations by dense non-native vegetation. More establishment trials in a wider range of locations are needed to determine whether a suitable niche can be found, thus allowing the species can become self-sustaining. One such initiative is currently under way at High Hill, where attempts have been made to populate the species on grassy slopes and open pine forest. Meanwhile, seed has added to long-term storage on-island and at Kew's Millennium Seed Bank in the UK.
An additional obstacle to the early reintroduction efforts arose from the risk of hybridization. Crosses between Trochetiopsis ebenus and the congeneric Redwood (T. erythroxylon (G.Forst.) Marais) are fully fertile and easily produced by natural cross-pollination if the two species are grown in close-proximity. Many specimens of the 'Rebony' (T. ebenus × erythroxylon) were inadvertently introduced to Ebony Plain and High Peak. Since the issue was recognized, protocols have been established to avoid further genetic contamination, and removal of Rebonies from problem situations is encouraged where necessary.
Plans to establish a Sandy Bay National Park are currently in development, and the protected zone will encompass Ebony Point. The species will also be protected under the new Environmental Protection Ordinance, presently in the final stages of drafting and expected to be issued in 2016. However, as the extant population occurs on a sheer cliff, it already suffers little threat from human interference.
