Sustainability Spotlight: Irrigation

September 16 @ 12:30 pm – 1:30 pm
Centre Street Gate 8V2F+WQJ, Boston

As climate change leads to increased temperatures and extreme weather patterns, drought is becoming more and more of a concern at the Arboretum. Staff have been working hard to install irrigation systems around the landscape since the record-breaking drought of 2016, working to increase the resiliency of our collections to periods of drought and dry weather, and this fall represents one of the biggest irrigation projects yet. Join Head of Operations and Project Management Danny Schissler and Head Operator Jed Romanowiz to learn how the Arboretum keeps trees watered in areas without irrigation, the Arboretum’s plans for new irrigation installations, and how all of these systems actually work.

Rooted in history.

The Arnold Arboretum sits on land long inhabited by Indigenous Peoples, most recently the Massachusett Tribe, and on property purchased with wealth from goods produced by enslaved persons.

Free and open every day.

We are committed to the Olmstedian principle that everyone is entitled to open space, so our gates are open to everyone, every day, free of charge.

Funded by our community.

The Arnold Arboretum has been funded by the generosity of the supporting public since our founding in 1872. Give today and continue that legacy.
