Conservation practitioners in urban areas around the world are facing increasingly complex decisions about why, what, where, and when invasive alien species (IAS) management is required.

We reviewed the literature on IAS management approaches applied in urban areas and evaluated whether prioritization, management thresholds, and decision triggers are used to inform the management of biological invasions.

The review showed that the elements informing IAS management decisions in urban areas are still poorly understood and biased, suggesting that these decisions are made on an ad hoc basis and/or are prompted by external factors that are not recorded in the formal literature.
