Invasive Spread Modeling in Manhattan by Alison Robey ’20, Mathematics Colloquium, Wednesday, September 18, 1 – 1:45 pm, Stetson Court Classroom 110

Abstract:  The thoroughly developed nature of Manhattan Island provides a unique model for invasive species spread: only in a place so built-up and seemingly cut-off from nature can the causes of the spread be so clearly isolated. Since most large plants on Manhattan can only survive in isolated, clearly delineated patches like gardens and parks, the persistence and success of the invasive (and destructive) plant Japanese knotweed (Reynoutria japonica) in spreading throughout the island is cause for surprise and alarm. This study examines the information available on urban invasive spread, Japanese knotweed spread, and park management to form a theoretical model of how such a takeover is possible and how it might be counteracted.
