Threats to shrubby tororaro
Habitat fragmentation and destruction
Stock presence and agricultural development have reduced shrub populations. Populations have also become isolated, leading to limitations on seed dispersal and colonisation.
Predation and trampling
Rodents are a threat
Rodents eat seeds, while snails and slugs are thought to eat any seedlings which may germinate. The shrub is also vulnerable to browsing by introduced animals.
In many places plants occur singly or in small single sex groups preventing seed production.
Disease, single-sex populations, competition, and damage caused by river gravel extraction are less significant causes of decline.
Potential for recovery
The recovery potential of the tororaro is excellent.
This is because the species is easily cultivated, grows well from seed and cuttings, and exhibits an immediate response to management.
