What is Rapid ʻŌhiʻa Death?

Rapid ʻŌhiʻa Death (ROD) is a disease affecting ʻŌhiʻa trees (Mestrosideros polymorpha) in Hawaiʻi. It can lead to wilting and death of these Native Hawaiian trees.

There are two types of Rapid ʻŌhiʻa Death: Ceratocystis lukuohia and Ceratocystis huliohia. Both are fungal pathogens causing the disease in ʻŌhiʻa trees.

Currently, there is no known cure for ROD. However there are ways to prevent the spread of this disease.

What are ʻŌhiʻa Trees?

ʻŌhiʻa trees (Metrosideros Polymorpha) are crucial to Hawaiʻi’s ecosystems. They provide habitat for native species, contribute to watershed health, and play a vital cultural role. The blossoms are also a symbol of love and are used in traditional Hawaiian ceremonies. The loss of lehua trees to Rapid ʻŌhiʻa Death threatens biodiversity, water resources, and cultural practices.

WAYS TO prevent the spread of ROD.

  1. Avoid spreading the disease: Clean your shoes, gear, and equipment before and after entering forests. The fungus can be spread through contaminated soil and plant material.

  2. Respect quarantine zones: If there are quarantine zones in place, adhere to them and prevent further spread.

  3. Promote healthy forests: Support initiatives that focus on maintaining overall forest health. This includes controlling invasive species and preventing additional stress on ʻŌhiʻa trees.

  4. Report suspected cases: If you observe symptoms of ROD, report them to local authorities promptly.

    Always stay informed about the latest recommendations and guidelines from forestry and agriculture agencies in the affected regions.
