ABSTRACT

Biological control is an effective and sustainable method for management of invasive alien plants (IAPs), and has been implemented on 68 of the 367 plant species that are listed as legally requiring management strategies under South Africa’s National Environmental Management: Biodiversity Act (10/2004): Alien and Invasive Species Regulations. With limited resources and funding available, it can realistically only be considered for a subset of the remaining alien plants for which biocontrol has not yet been implemented. Considerable funding has been allocated towards biocontrol in South African in the past, principally through the Working for Water Programme of the Nature Resource Management Programmes (Department of Environment, Forestry and Fisheries), and this support is expected to continue with the intention of increasing the number of IAPs under this management approach in the future. To ensure appropriate targets are selected, the Biological Control Target Selection (BCTS) system was applied to the alien plants on this list that are not under biocontrol (299 species). This paper presents the resultant list of top priority species that represent good investments for biocontrol when funds are available.

摘要

生物控制是管理外来入侵植物 (IAP) 的一种有效且可持续的方法，并已在南非《国家环境管理：生物多样性法案》(10/2004) 列为法定管理战略的 367 种植物物种中的 68 种实施)：外来和入侵物种条例。由于可用的资源和资金有限，实际上只能考虑对尚未实施生物控制的剩余外来植物的一个子集。过去，南非为生物防治分配了大量资金，主要是通过自然资源管理计划的水资源工作计划（环境、林业和渔业部），并且这种支持预计会继续下去，以期在未来增加这种管理方法下的 IAP 数量。为确保选择适当的目标，生物控制目标选择 (BCTS) 系统应用于此清单上不受生物控制的外来植物（299 种）。本文列出了在资金到位时代表生物防治良好投资的最优先物种列表。
