External Group Support/Co-Organization: Rapid ʻŌhiʻa Death Working Group.
Description: The proposed session will delve into the critical topic of Rapid 'Ōhiʻa Death (ROD), a complex of two devastating fungal diseases affecting 'Ōhiʻa trees (Metrosideros polymorpha) across Hawai'i. This issue holds significant ecological and cultural relevance, as 'Ōhiʻa trees are keystone species in Hawaii's native forests and carry deep cultural importance for local communities.
Understanding the biology and management of ROD is crucial for developing effective strategies to combat this disease and preserve these vital ecosystems. This session will provide attendees from various countries with a unique opportunity to learn about this Hawaii-specific disease, offering valuable insights applicable to other regions vulnerable to similar threats.
By presenting the latest updates in biological research and interdisciplinary approaches, this symposium aims to foster a deeper understanding of ROD and promote collaborative efforts in managing and mitigating its impact. Attendees will gain comprehensive knowledge of the disease’s biology, the role of invasive species, and the advanced scientific techniques guiding current management practices.
This symposium’s presenters are subject matter experts who will share their contributions to the science of ROD and advancements in disease management. The session will cover various scientific disciplines involved in this multi-faceted issue, including plant pathology, disease resistance, entomology, remote sensing, and forest ecology, as they relate to this critically important disease system.
Plant Health 2025 Theme: Our symposium on Rapid 'Ōhiʻa Death (ROD) aligns well with the Plant Health 2025 theme, "Global Communities Collaborating to Address Global Risks," by tackling a critical plant health threat in Hawaiʻi. By uniting international experts and researchers, the session embodies the collaborative spirit essential for addressing global plant health challenges. We will share cutting-edge research and management strategies applicable to regions facing similar threats, promoting innovative interdisciplinary approaches.
Our talks will focus on a Hawaii-specific novel disease issue, addressing the impacts of this newly introduces invasive species, the deep cultural ties to 'Ōhiʻa trees, and the challenges of biological invasions and biosecurity. Attendees will gain insights into disease resistance strategies, enhancing their understanding and ability to contribute to global plant health solutions.
