Using next generation sequencing to explore the taxonomic identity of a potentially new invasive Magnolia tree in Canada

The Royal Botanical Gardens (RBG) in Hamilton, Ontario, face a challenge as Magnolia seedlings have been escaping from their arboretum and naturalizing in nearby forested ravines over the past 12–14 years. Although RBG staff suspect these populations stem from Magnolia kobus, the presence of various cultivars and hybrids complicates identification through morphological observation alone. To address this, the project will use advanced next-generation DNA sequencing to accurately identify the taxonomic origin of the escaped populations and trace them back to specific trees in the arboretum. Identifying the source will allow RBG to manage and control these populations effectively, while preserving as much of their valuable horticultural Magnolia collection which includes trees that have been growing for over 80 years, and are very difficult to replace. This project will help RBG balance ecological conservation with the careful curation of its Magnolia collection, a key attraction for visitors during the spring season.
