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
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 •
CHANGES SINCE 2011 SOE ASSESSMENT
The 2016 assessment is similar to the 2011 assessment.
QUALITY OF DATA USED IN THE ASSESSMENT
Publications are based on the best data available, the NIMPIS website relies on submission of information to NIMPIS administration
and QC’d by the Department of Agriculture.
CUSTODIAN AND LOCATION OF DATA
Data in individual peer-review papers and reports are the IP of the relevant authors and institutions, marine pests website
copyright Commonwealth of Australia (details of specific data sets used to generate the assessment have not been provided).
METHOD USED TO DETERMINE STATE OR RECENT TREND
There are currently no systemic surveys carried out to determine the abundance of NIMPIS pests. Identification of state
is therefore based on reporting rates of NIMPIS-listed pests presence only.
