Troy University Arboretum, Arboretum at Troy University, Alabama, US.

Troy University Arboretum covers 75 acres beside the Troy University campus in Troy, Alabama, and is managed by the Department of Biological and Environmental Sciences. It holds over 300 tree species from the southeastern United States and the Wiregrass Region, a 2.5-mile nature trail through a swamp and stream, and the 4-acre Mullis Pond.

This arboretum began as a collection and display space for trees and plants representing the natural heritage of the Wiregrass ecosystem. Over time it developed into a research site for understanding and protecting the region's native flora and wildlife patterns.

The arboretum is managed by the Department of Biological and Environmental Sciences of Troy University's College of Arts and Sciences, which uses it to supplement its teaching and research programme. A herbarium founded in 1954, holding over 35,000 specimens, mainly vascular plants of southeast Alabama, supports this work.

The arboretum is open to the public and lies next to the Troy University campus in Troy, Alabama. A 2.5-mile nature trail runs through a swamp and along a stream to Mullis Pond, a 4-acre pond. The separate Pocosin Nature Preserve, a swamp reserve, sits about 10 km east of Troy.

The arboretum is managed by the Department of Biological and Environmental Sciences of Troy University's College of Arts and Sciences, and its herbarium, founded in 1954, holds over 35,000 specimens, mainly vascular plants, with about 3,000 added each year.
