Cyrtandra heinrichii is a shrub that usually grows by waterfalls on walls of basalt. They are also found in shrubland and wet, tropical or sub-tropical forests dominated by Metrosideros. This species can usually be found with ferns at altitudes between 730m and 1,350m.

This species is closely related to Cyrtandra wawrae.

Conservation and threats

Cyrtandra heinrichii is listed as endangered by the IUCN. It occupies an area of 10km2. There are estimated to be between 250 and 1,000 mature individuals left in the declining population, fragmented into 9 subpopulations. Part of the species range lies within a Natural Area Reserve.

Damage to the plant by slugs and rodents, habitat destruction from wild pigs, and invasive plants species all pose a serious threat to this taxon. These invasive species compete with lava cyrtandra for resources. Such plant species include, but are not exclusive to:

In addition, the decline of native bird and insect species has led to a decrease in pollination.
