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

Brief description

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 ASSESSMENT There 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 ASSESSMENT This 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: Good Assessment trend: Stable Confidence grade: Limited evidence or limited consensus Confidence trend: Limited evidence or limited consensus Comparability: Grade and trend are comparable to the 2011 assessment • 2011 • Assessment grade: Good Assessment trend: Stable Confidence grade: Limited evidence or limited consensus Confidence trend: Limited evidence or limited consensus ---------------------------------------- CHANGES SINCE 2011 SOE ASSESSMENT The 2016 assessment is similar to the 2011 assessment.
