The invasive disease has the potential to damage many ecologically, economically, and culturally significant tree species including pōhutukawa, rāta, and mānuka which are members of the myrtle family.
Mauao has a large number of these trees, particularly pōhutukawa which often features in themany photographs taken of the mountain each summer.
Mauao Trust posted on its Facebook page yesterday that Myrtle Rust was “unfortunately now present on Mauao”.
It said its myrtle rust researcher met with scientists from Scion to analyse the rust.
Andy Munn snapped this gorgeous pic of pohutukawa framing Mount Maunganui from Mauao.
Myrtle rust spores are microscopic and travel large distances by wind, or by insects, birds, people, or machinery. It is believed that wind carried spores here from Australia, where myrtle rust was first found there in 2010.
“The best thing we can all do to stop the spread at this stage is keeping to the tracks. Please get that message out there,” the Trust stated.
People were encouraged to message the trust with a photo and location on Mauao if they found any rust on pōhutukawa.
The fungus has spread rapidly since the first case in New Zealand was identified in 2017.
Tauranga City Council has been contacted for comment.
Make sure you label your finds as myrtle rust, noting what host plant it has been found on. This information helps experts confirm if the signs are correct.
