2016 SoE Marine Chapter - State and Trends - NIMPIS-listed pests

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "The state and trends of non-indigenous/non-endemic species – number and abundance of NIMPIS-listed pests". The full Expert Assessment, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Expert Assessment are accessible through the "On-line Resources" section of this record.----------------------------------------DESCRIPTION OF ECOLOGICAL PROCESS FOR EXPERT ASSESSMENTThere are over 250 introduced marine plants and animals established in Australian waters (see marine pests.gov.au). Some have hitch-hiked to Australian waters on the hulls of vessels of all types from yachts to commercial ships, or in their ballast water. Others have been introduced to support local aquaculture, with the aquarium industry another vector. Species that are listed on the National Introduced Marine Pest Information System are those known to have been introduced to Australia, or considered to be a risk of future introduction. NIMPIS currently contains detailed information on over 100 invasive marine species.DATA STREAM(S) USED IN EXPERT ASSESSMENTThis assessment is based on peer-review papers and reports as well as information on the marine pests website: see http://www.marinepests.gov.au.----------------------------------------2016 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details]• 2016 •Assessment grade: GoodAssessment trend: StableConfidence grade: Limited evidence or limited consensusConfidence trend: Limited evidence or limited consensusComparability: Grade and trend are comparable to the 2011 assessment• 2011 •Assessment grade: GoodAssessment trend: StableConfidence grade: Limited evidence or limited consensusConfidence trend: Limited evidence or limited consensus----------------------------------------CHANGES SINCE 2011 SOE ASSESSMENTThe 2016 assessment is similar to the 2011 assessment.

2016年《环境状况报告（State of the Environment, SoE）》海洋章节整合了多套基于海洋数据流生成的专家模板。本元数据记录针对专家评估报告《非本土/非特有物种的状况与趋势——国家外来海洋有害生物信息系统（National Introduced Marine Pest Information System, NIMPIS）收录有害生物的数量与丰度》进行说明。本记录附件包含完整的专家评估报告，含附图及附表（如已提供）。若有可用数据，生成该专家评估所使用的数据流可通过本记录的“在线资源”板块获取。

【专家评估的生态过程说明】
目前澳大利亚海域已确立的外来海洋动植物物种超过250种（详见marinepests.gov.au）。部分物种通过各类船舶（从游艇到商用船舶）的船底附着，或船舶压载水被意外引入澳大利亚海域；另有部分物种为支持本地水产养殖活动而被引入，观赏水族行业亦是另一传播媒介。被纳入国家外来海洋有害生物信息系统（NIMPIS）的物种，均为已知已传入澳大利亚，或被认定存在未来传入风险的物种。目前NIMPIS收录了超过100种入侵海洋物种的详细信息。
