BLOOMINGTON, Ind. (AP): A committee created by Indiana lawmakers to devise new ways of controlling invasive plants estimates land owners and managers spent $5.85 million last year to manage invasive plants. The Invasive Plant Advisory Committee surveyed 116 agencies, land trusts and others, representing more than 650,000 acres of managed public and private land. Panel member Ellen Jacquart says the survey shows how invasive species have gotten a strong foothold in Indiana.
