Rare Isis Tamarind only found in Bundaberg Region

The Isis Tamarind is one of the rarest trees in the world, and it’s only found in the Bundaberg area. As a part of the Bundaberg Botanic Gardens Plant Series, curator Cody Johnston chats about what makes this tree so special.

Did you know the Bundaberg Region is home to one of Australia's most unique trees, the Isis Tamarind?

The Australian Government has officially listed the tree as endangered.

The Isis Tamarind grows to 16 metres in height and three can be seen in the Bundaberg Botanic Gardens.

There is a small population of 17 mature individuals in the Cordalba Forest Reserve and several remnant populations totalling just 26 known individuals.

Remnant patches have been found near roadsides and on margins of agricultural land.

Flowering occurs in month-long episodes in spring and summer and flowers display to attract insect pollinators including Tetragonula carbonaria (the stingless bee) and various species of butterfly.

Pollen transfer between male and female trees is required for seed set.

Much of the original habitat has been cleared for agriculture and the resultant fragmentation is a threat to this species, as well as pollinator disturbance, maintenance activities, competition and grazing.

  1. Does the council intend propagating plants for the public to buy and plant on their land? Are they an evergreen tree? There does not seem to be too much info on this species.
