Merremia tuberosa is known to overgrow and smother tall hardwood forest canopies. This perennial vine blocks sunlight from trees and the understory, killing native trees and shubs. M. tuberosa has been especially problematic on the island of Niue where it has spread quickly and aggressively (Space & Flynn, 2000). It is also reported to be toxic to animals and humans and should not be ingested by either (Smith, undated; PIER, 2005; Motooka et al, 2003; Orapa, 2003; Space & Flynn, 2000; Staples 2010).
