到2020年，查明外来入侵物种及其入侵路径并确定其优先次序，优先物种得到控制或根除，并制定措施对入侵路径加以管理，以防止外来入侵物种的引进和种群建立。

到2020年，采取措施防止引入外来入侵物种并大幅减少其对土地和水域生态系统的影响，控制或消灭其中的重点物种

Explanation: Actions are taken to understand, quantify and eliminate or reduce the negative impact of invasive alien species on migratory species and their habitats.

Invasive alien species and pathways of introduction and expansion are identified and prioritized, priority invasive alien species are controlled or eradicated, and management responses are prepared and implemented to prevent their introduction and establishment.

Baseline

• 36% of Parties have established national policies or guidelines on invasive species control and management. (National Reports to COP12).
• 20% of Parties have a national inventory of invasive alien species that currently or potentially impact the ecological character of wetlands. (National Reports to COP12).

Indicator

• % of Parties that have established or reviewed national policies or guidelines on invasive wetland species control and management. (Data source: National Reports).
• % of Parties having a national inventory of invasive alien species that currently or potentially impact the ecological character of wetlands. (Data source: National Reports).

Possible further indicators that may be developed

• {Number of invasive species that are being controlled through management actions}
• {Effectiveness of wetland invasive alien species control programmes}

Rational

Plant pests that are invasive alien species can have a significant and devastating impact on the terrestrial, marine and freshwater environments, agriculture and forests. Strategic Objective B addresses environmental concerns related to plant biodiversity and emerging problems associated with plant pests as invasive alien species and the impacts of climate change.

B1: Contracting parties recognize the management of environmental plant pests as part of their responsibilities and work with national environmental sector agencies to support pest management programmes aimed at environmental protection.

B2: Contracting parties have mechanisms in place to control the spread of environmental contaminating pests on non-plant trade pathways (e.g. invasive ants on vehicles and machinery, or gypsy moth egg masses on sea containers and vessels).

B3: Mechanisms are in place to share adaptation strategies for responding to the impacts of climate change.

B4: Agencies with environmental and forest biodiversity stewardship responsibilities regularly access information and other resources managed by the IPPC Secretariat.

B5: Contracting parties continue to improve their capacity to implement key IPPC standards which directly address the spread of forest and environmental pests, such as ISPM 15 on wood packaging materials and other such standards, to contain the global spread of pests which threaten forests, biodiversity and non-cultivated flora.
