Invasive plants are not typically prohibited from the nursery trade until after the species has already spread prolifically throughout an ecoregion. However, a proactive new approach evaluates the threats of invasive plants before they become a significant problem. This Native Plant Trust webinar on April 12 from 1 – 2 offers a regional proactive approach to listing invasive plants, with a focus on early detection of potential invasive plants that may become established in New England. Bud Sechler leads the talk, and it’s $15 for NPT members, $18 for nonmembers. Register at http://www.nativeplanttrust.org/events/early-detection-invasive-plants/
