programmes that aim to manage the impacts of invasive alien species within a site/area through both implementation of control measures and where necessary restoration (sometimes referred to as asset protection) e.g., within high value protected sites/areas.

selected locations with heightened levels of detection and effective reporting through concentration of activities on subpopulations to enhance detection and improve cost-effectiveness of invasive alien species surveillance efforts

export of products that are free from invasive alien species

probability of the occurrence of a particular adverse event at a specific time and the magnitude of the consequent damage caused, depending on various factors such as exposure to the hazard, the frequency of exposure and the severity of any consequent damage done (FAO, 2011b). The term risk is regarded as a product of three factors: Exposure x Likelihood x Consequence (Kinney & Wiruth, 1976).

any intentional activity that initiates or accelerates the recovery of an ecosystem from a degraded state (IPBES glossary). More specifically, in the context of invasive alien species management, it refers to the process of assisting the recovery of a degraded, damaged, or destroyed ecosystem, as a consequence of biological invasions, to reflect values regarded as inherent in the ecosystem and to provide goods and services that people value

for the purpose of this assessment, the ability of an ecosystem to adapt, withstand and respond to alien species invasions, recover rapidly from their impacts and continue to develop

“the current limits of distribution of a species, accounting for all known, inferred or projected sites of occurrence”

a measure of introduction intensity, including release from captivity or cultivation, comprising both the number of individuals of a species introduced per introduction (propagule size) and the frequency of introductions

for the purpose of this assessment, any policy and/or action/response undertaken to prevent the arrival and/or introduction of alien and invasive alien species, between and within countries and regions. Prevention is generally far more cost-effective and environmentally beneficial than measures taken following introduction and establishment of an invasive alien species

any policy and/or action undertaken to prepare for the probable arrival of a potential invasive alien species including any preventative or adaptive response activity
