Threats to Olearia hectorii

Threats include habitat loss and fragmentation, animal browsing, weed invasion, lack of seedling recruitment and loss of mature trees that could be a seed source.
Another threat is modified habitat where there is little natural disturbance, such as landslips. Land slides and flooding create open ground for germination and replacement seedlings.
Equally threatening for Hectors tree daisy is that the great majority of existing populations are of old, non reproducing trees. This means there is little replacement. In other words, as old trees die, Olearia hectorii will disappear from the landscape.
