This collection displays a variety of trees from arid lands used for scientific study and landscape design.
Purpose and scope of the collection
The Trees of the World collection serves as a resource for studies of species from warm desert or semi-arid places around the world. It features trees that are useful in urban residential, commercial, and public landscapes in the Las Vegas Valley and adjacent parts of southern Nevada with similar climatic conditions.
Collection — specific interpretations of this policy and special
- All trees should be accessioned as individuals within the Arboretum Core. All trees should be accessioned as individuals. Outside the Core, accession individual trees when they are part of a limited population of the species on campus.
- Only a few individual shrubs of each species should be accessioned, but they should be from different parts of the campus.
- Emphasize trees adaptable to Climate Zone 11 (Medium to High Deserts of California and Southern Nevada as defined in the Sunset Western Garden Book).
- However, utilize microclimates found on campus to support as many genera and species as practical.
- Display specimens in a variety of landscape uses and styles.
- Plant some trees in taxonomic exhibits (i.e., groups of related species) to facilitate comparison of growth habit among individuals of the same species and between species.
- Plant some trees in geographic exhibits (i.e., with shrubs from the same part of the world) to facilitate studies in ethnobotany and ecology.
