Linking Ecology and Horticulture To Prevent Plant Invasions: A Workshop, St. Louis, MO, Dec 1-4, 2001

乌鸦入侵植物是一个重大的经济问题，是对自然地区生物多样性保护的严重威胁。减少入侵者数量的努力不仅必须集中在控制现有物种上，而且还必须集中在确定引进途径以减少建立的途径上。这些非本土物种中的许多都是偶然引入的，但大多数是为了园艺用途而引入的。园艺用途的引种继续以很高的速度进行，已经在这里表现出入侵能力的物种很少被从使用中移除。研讨会将汇集政府、私人和学术界对生态和园艺的兴趣，以解决几个相关问题。被邀请的与会者将：1)为园艺领域中感兴趣的领域，包括苗圃、植物园、景观建筑师和园艺公众，制定具体的行为准则；2)评估和完善明确易用的方法和指南，以评估可能成为入侵有害生物的植物物种；以及3)制定和评估方法，以确定美国目前用于园艺的许多入侵物种的可接受替代品。其目的是，讨论将寻求所有各方都能接受的具体解决办法，并从讨论中确定研究和行动议程。研讨会的成果将提交给商业园艺和植物园社区，以及美国杂草科学协会，供讨论、改进和采用。

0133065Raven Invasive plants are a major economic problem and are a serious threat to the protection of biodiversity in natural areas. Efforts to reduce the number of invaders must focus not only on controlling existing species but also on identifying pathways of introduction to reduce establishment. Many of these non-native species were introduced accidentally, but the majority were introduced for horticultural use. Introductions for horticulture use continue at a high rate, and species already here that demonstrate invasive ability are rarely removed from use. The workshop will bring together government, private, and academic interests in ecology and horticulture to address several relevant issues. The invited participants will: 1) develop specific codes of conduct for interest areas within horticulture, including nurseries, botanical gardens, landscape architects, and the gardening public; 2) assess and refine explicit easy-to-use methods and guidelines for evaluating plant species for potential to become invasive pests; and 3) develop and assess methods to determine acceptable alternatives to many invasive species currently used in the United States for horticulture. It is intended that the discussions will search for concrete solutions acceptable to all parties and that, from the discussions, research and action agendas will be identified. The results of the workshop will be presented to the commercial horticulture and botanical garden communities, as well as to the Weed Science Society of America, for discussion, refinement and adoption.
