What you need to know

Climbing spindleberry smothers native vegetation, causing canopy collapse and suppressing native seedling recruitment. May overtop plantation trees and impede recreational access to natural areas.

Climbing spindleberry is declared an unwanted organism by the Ministry for Primary Industries (MPI) because it is capable of causing harm to the natural environment, physical resources or human health in Aotearoa/New Zealand.

These species pose a high risk to our environment, economy, recreation, and cultural values.
