The recovery plan (NPWS 1998)
calls for (a) restricting access to the populations by keeping their location
secret, (b) restricting access to the site to approved people, (c) instituting
strict hygiene protocols to avoid introducing disease, (d) fire
management and (e) maintaining ex-situ samples of each plant in
botanic gardens. Further, commercial propagation of the species is
increasing population size and reducing stochastic risks.
Ironically, in such a case, retention of just one individual retains the entire gene pool
of the species, although this would clearly be foolhardy in terms of increased extinction risk from non-genetic causes. Plant species in this situation have an advantage over animals, in that many can be propagated by cuttings.
