北美园艺业进口植物存在意外引入有害非本地物种的风险。该行业每年支付的许可费将降低这种风险，同时为研究、筛选进口物种、教育和消除过去的植物入侵筹集资金。然而，实施此类费用需要了解引进物种需要多长时间才能定居以及其传播速度和环境破坏的信息。就估算正确税收所需的科学数据而言，实施此类政策将具有挑战性。与其他阻止入侵的政策选择相比，利益相关者对年费的支持也有限。首选政策是筛查所有新引进的植物，并禁止那些极有可能成为潜在入侵物种的物种。强制实施该计划优于园艺业自愿实施。
Plant imports by the North American horticultural industry risk the accidental introduction of harmful nonnative species. An annual license fee paid by the industry would reduce this risk while raising funds for research, screening imported species, education, and the eradication of past plant invasions. However, implementing such a fee requires information on how long it takes introduced species to become established and on their spread rates and environmental damages. Implementing such a policy would be challenging in terms of the scientific data required to estimate the correct tax. There is also limited support among stakeholders for an annual fee compared with other policy options to stop invasives. The preferred policy is to screen all newly introduced plants and to ban those species with a high likelihood of becoming a potential invasive. Mandatory implementation of this scheme is preferable to voluntary implementation by the horticultural industry.
