The Harold L. Lyon Arboretum is a 200-acre botanical garden and arboretum located at the upper end of Mānoa Valley on the island of Oʻahu, Hawaiʻi. It is managed by the University of Hawaiʻi at Mānoa. The arboretum was founded in 1917 by Harold L. Lyon, a professor of botany at the university.
The arboretum’s collection includes over 3,000 species of plants from around the world, with a focus on plants from the tropics and subtropics. The collection includes plants from Hawaiʻi, Southeast Asia, Africa, South America, and other parts of the world. The arboretum also has a number of endangered and threatened plant species.
The arboretum is a member of the Botanic Gardens Conservation International (BGCI) and the International Union for Conservation of Nature (IUCN). The arboretum works with the IUCN to assess the conservation status of plants in Hawaiʻi and to develop conservation plans for endangered and threatened plant species.
The arboretum is open to the public and offers a variety of educational programs and events. The arboretum is a popular destination for hikers, birdwatchers, and nature lovers.
Here are some specific examples of the arboretum’s work with the IUCN:
- The arboretum is a participant in the IUCN Red List of Threatened Species. The arboretum provides data on the conservation status of plants in Hawaiʻi to the IUCN. This data is used to assess the risk of extinction of plant species and to develop conservation plans.
- The arboretum is a participant in the IUCN Species Survival Commission (SSC). The SSC is a network of scientists and conservationists who work to conserve threatened and endangered species. The arboretum works with the SSC to develop conservation plans for endangered and threatened plant species in Hawaiʻi.
- The arboretum is a participant in the IUCN Botanic Gardens Programme. The Botanic Gardens Programme is a global network of botanical gardens that work to conserve plant diversity. The arboretum works with the Botanic Gardens Programme to share resources and expertise on plant conservation.
The Harold L. Lyon Arboretum is a valuable resource for plant conservation in Hawaiʻi. The arboretum’s work with the IUCN is helping to ensure the survival of endangered and threatened plant species in the state.
