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

[133065]入侵植物是一个严重的经济问题，严重威胁着自然地区生物多样性的保护。减少外来物种数量的努力不仅要注重控制现有物种，而且要确定引进途径，以减少外来物种的数量。这些非本地物种中有许多是偶然引进的，但大多数是为了园艺用途而引进的。用于园艺用途的引进继续以很高的速度进行，并且已经在这里显示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学和园艺学的兴趣，以解决几个相关问题。受邀参加者将：1)为园艺学领域（包括苗圃、植物园、景观设计师和园艺公众）制定具体的行为准则；2)评估和完善明确的易于使用的植物物种潜在入侵性评估方法和指南；3)开发和评估方法，以确定目前在美国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.
