Ex situ conservation is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat. For example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, such as a zoological park or wildlife sanctuary. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality.
Banksia cuneata, commonly known as matchstick banksia or Quairading banksia, is an endangered species of flowering plant in the family Proteaceae. Endemic to southwest Western Australia, it belongs to Banksia subg. Isostylis, a sub-genus of three closely related Banksia species with inflorescences or flower clusters that are dome-shaped heads rather than characteristic Banksia flower spikes. A shrub or small tree up to 5 m (16 ft) high, it has prickly foliage and pink and cream flowers. The common name Matchstick Banksia arises from the blooms in late bud, the individual buds of which resemble matchsticks. The species is pollinated by honeyeaters (Meliphagidae).

The species is endemic to the Santa Cruz Mountains within the Santa Cruz and San Mateo counties of west-central California.

Ring width almost correlates with rainfall due to such harsh environmental conditions It is threatened by habitat loss and protected in South Africa under the National Forest Act of 1998.
Iliamna is a small genus of flowering plants in the mallow family, endemic to North America. It is related to the bush mallows of California (Malacothamnus) and to Phymosia of Mexico, Central America and the Caribbean. These perennial herbs are known commonly as wild hollyhocks and sometimes as globe mallows, Kankakee mallow, Kankakee globe mallow, and Streambank wild hollyhock. More often, the latter terms refer to members of the genus Sphaeralcea, which belong, like Iliamna, to the "typical" mallow tribe (Malveae) of the mallow and hibiscus subfamily Malvoideae. The name of the genus, proposed by Edward Lee Greene, appears to be a reference to Iliamna Lake in Alaska, even though the genus Iliamna does not occur in Alaska
Iliamna rivularis, known by the common name streambank wild hollyhock, is a perennial plant species in the family Malvaceae.
