Impacts

Cathedral bells, native to Central and South America, is a fast-growing evergreen climber (to 10 metres). The long-lived vines can grow over trees and shrubs forming a dense canopy that smothers desirable vegetation and impedes access to areas.

Why is it a pest?

Cathedral bells is a vigorous, fast growing perennial climber with stems to 10m long. Its long-lived vines can establish and grow along riverbanks, forest margins and roadsides, in shrubland, open areas, hedges, and shelterbelts. It forms a dense canopy over trees and shrubs that smothers native vegetation and prevents seedling establishment. Walls of cathedral bells vines can obstruct access to areas.

Cathedral bells can grow well under a range of environmental conditions including shade, drought, wind, salt, and differing soil types. It produces large numbers of viable seeds that can be dispersed by wind and water. However, new plants can also establish from stem fragments, and the plant is most often spread via dumping of garden waste or soil movement. .

It is currently largely restricted to a few sites adjacent to the Waikato River at Karāpiro and Ngāruawāhia, in Hamilton City, at Thames, Cooks Beach and Whangamata on the Coromandel, and in the King Country near Te Mapara and Ōtorohanga.
