National Biosecurity Week | Safeguarding Australia Together
Botanic gardens play a critical role in protecting Australia's plants from emerging pests and diseases.
Globally they contain an estimated 30% of all known plant species, making them valuable sentinel sites that can help detect new biosecurity threats before they become widespread.
At the Royal Tasmanian Botanical Gardens, we're proud to be part of Plant Health Australia's Botanic Gardens and Arboreta Surveillance Network, helping monitor for high-priority plant pests and diseases that threaten native flora, horticulture and agriculture.
As part of our biosecurity surveillance work, some of the sentinel species that we regularly inspect include:
๐ฟ willow myrtle (Agonis flexuosa)
๐ณ oriental plane (Platanus orientalis)
๐ English oak (Quercus robur)
๐น Rosa 'Edelweiss'
๐ white mulberry (Morus alba)
These plants help us identify signs of pests and diseases that could pose risks to Tasmania and Australia. Explore these plants through our Flora Map database, accessible via the RTBG website.
