Tucson Plant Materials Center

Tucson, Arizona

Tucson Plant Materials CenterEstablished 1935

In 1934, the first Plant Materials Center was established in Tucson, Arizona, under the direction of F. J. Crider. During this time, the primary mission of the Tucson Plant Materials Center (AZPMC) was the production of nursery stock and the collection of large quantities of seeds for use on the Navajo, Gila, and Rio Grande regional projects. The Center’s mission has evolved to address current conservation needs such as erosion, drought, pollinator conservation, water quality, wildlife habitat, energy demands, and wildfire damage.

The AZPMC service area encompasses the Sonoran, Chihuahuan, and Mohave deserts in areas of Arizona, California, Nevada, New Mexico, and Utah. Major land uses in this area include irrigated farmland, rangeland, and minelands. The Center develops and evaluates adapted plant materials and technologies for needs throughout the service area.

The Center’s releases include a variety of conservation shrubs and grasses such as, ‘Santa Rita’ fourwing saltbush, ‘Loetta’ Arizona cottontop, Batamote Germplasm desert zinnia, and Vegas Germplasm alkali sacaton. Many of these releases were developed in collaboration with partners such as the Bureau of Land Management, University of Arizona, and the Agricultural Research Service.
In 1996, the Tucson Plant Materials Center was placed on the National Register of Historic Places.
