The team created an online 調査する and received 報告（する）／憶測s from 558 gardeners, 明らかにする／漏らすing more than 200 可能性のある invaders.?
An 分析 of the results, considering both 国内の and 全世界の invasive status, 許すd the 研究員s to prioritise five ornamental 工場／植物s of 関心.?
'The simple yet structured 計画／陰謀 we developed was used to prioritise which of the around 70,000 ornamental 工場／植物s 利用できる to buy in the UK could be 未来 invaders,' said lead author, Tomos Jones.?

'This is 決定的な for 焦点（を合わせる）ing 研究 成果／努力s and 資源s, such as 行為／行うing formal 危険 査定／評価s to 調査する the invasive 可能性のある of those shortlisted.'?
The 研究員s 最高潮の場面 five shortlisted 工場／植物s, which many Britons may already have in their gardens:
- Mexican fleabane (Erigeron karvinskianus) - a perennial 工場／植物 with 狭くする, hairy leaves and daisy-type flower-長，率いるs.?

Based on the findings, the 研究員s are calling for 当局 to 査定する／（税金などを）課す the 可能性のある for these 工場／植物s to become invasive in Britain and Ireland, before it's too late.?
'The period between introduction of a 種類 and it first 存在 noticed as a problem can be a long one, making 未来 支配（する）／統制する problematic,' the team 追加するd.?
