Markley Arboretum |
The mission of the Markley Arboretum is to steward and enhance a diverse collection of trees and associated plant communities that demonstrate the successful integration of ecological conservation, urban forestry, and critical technology infrastructure while contributing to the environmental health of the Concord River Watershed.
The Markley Arboretum will open to the public annually to celebrate Arbor Day, giving people the opportunity to participate in guided walking tours around the entry area, evergreen hills, and wetland conservation area.

As a private data center campus, the Markley Arboretum serves as a model for integrating environmental stewardship with critical infrastructure. The plan promotes long-term sustainability, enhancement of urban tree canopy within the Concord River Watershed, and ongoing appreciation of trees and biodiversity by employees, visitors, and the community.
