Case Overview:
New York Botanical Garden’s cultivated arboretum and gardens include valuable mature ash specimens of various species. NYBG has invested in treating mature ash specimens across its cultivated landscape to support its horticultural, ecological, scientific and educational work. Regionally native ash that are being treated across the landscape include white ash (Fraxinus americana), which is naturally occurring at the Garden, and blue ash (Fraxinus quadrangulata), which is native to the Midwest. The Garden plans to retain these important trees on the landscape over the long term by continuing treatments in the future if necessary. 

Silviculture Objectives:
As the ash are being treated in the cultivated landscape of a botanical garden, the main objective is to retain these valuable trees in the collection and prevent their loss from emerald ash borer infestation. These trees are important for the larger horticultural, educational, scientific and ecological goals of the institution.

Landowner Objectives:
The primary objective of this specific project is to preserve mature ash specimens in the cultivated landscape to support the Gardens ecological, scientific, educational and horticultural work.

Silviculture Prescription:
This site is a cultivated landscape that encompasses an arboretum and gardens. For this SAP-NE project, 6 mature ash specimens will be treated to protect them from emerald ash borer impacts.

Factors Influencing Prescription Choice:
- forest health

Equipment used:
Staff followed pesticide label instructions for chemical treatments.

Prescription Notes:
Chemical treatments have allowed us to preserve mature ash across the Garden landscape.
