Integrating invasive species policies across ornamental horticulture supply chains to prevent plant invasions

“…For example, in both Great Britain and New Zealand, there is an order of magnitude greater number of plant species in cultivation than native plant species in the wild (Armitage et al, 2016;Gaddum, 1999). In the United States, alien species comprise as much as 80% of the stock held by nurseries (Brzuszek & Harkess, 2009;Harris, Jiang, Liu, Brian, & He, 2009) and account for up to 90% of nursery revenue (Kauth & Perez, 2011). While only a relatively small proportion of taxa escape cultivation, often less than 10% (Hulme, 2012), the sheer number of taxa cultivated results in the ornamental pathway being the main source of naturalized and invasive alien plant species in natural areas world-wide ( Figure 1).…”
