* 'Caution' designation indicates that the assessment could not be completed due to lack of information on the impacts of this species in Indiana, but that there is potential for invasion and impacts.
IPAC is developing an invasive plant list for Indiana using a science-based, transparent risk assessment process. Plants in trade are being assessed using the same risk assessment tool used by the Invasive Plants Species Assessment Working Group (IPSAWG). Plants not in trade are being assessed using a simpler tool developed in New York.
Plants in trade already assessed by IPSAWG: Thirty-two species were assessed by IPSAWG from 2000 to 2006. As part of the process, each assessment was developed by a subcommittee and then reviewed and approved by the IPSAWG committee. These assessments were developed based on the best information available at the time, and recently have been updated to reflect new information from the literature; maps showing the known range of these species in Indiana outside of cultivation have also been added. The new information from the literature resulted in a few changes to the scoring of the assessments. All these updated IPSAWG assessments can be accessed at https://drive.google.com/#folders/0B3fp0k5tx4KwY3NvY0FRZWg2QUE. Comments may be made in each document listed there, and will be incorporated as appropriate into the final document.
Plants in trade not assessed by IPSAWG: These species are being assessed using the same IPSAWG assessment tool and can be accessed in the New IPSAWG Assessment folder at https://drive.google.com/#folders/0B3fp0k5tx4KwUDdzWVYtVlMwZTg. Comments may be made in each document listed there, and will be incorporated as appropriate into the final document.
Plants not in trade: Assessments for plants that are not in commercial trade are being posted at https://drive.google.com/#folders/0B3fp0k5tx4KwakVGVEVQTlItU2s. Comments may be made in each document listed there, and will be incorporated as appropriate into the final document.
