plant species
The Organ Pipes National Park is an example of a recreated basalt plain grassland. Some of the species within the park are endangered outright or in danger of becoming locally extinct. An example is Callitris columellaris, the Murray River cypress-pine (sometimes known as Callitris glaucophylla). This species has been significantly affected by European settlement. Some trees in and near the park are thought to be over a hundred years old, and are probably the best protected occurrence of the species south of the Great Dividing Range.
