摘要

Considerable effort goes into keeping weedy species out of Australia but is enough being done to detect species that are already naturalising here and likely to become major problems? We argue that a number of species that government authorities havebeen attempting to keep out are already naturalised here and greater effort and resources need to go into their early detection. Examples of such species recently found naturalised in Australia include Asystasia gangetica (L.) T. Anderson subsp. micrantha (Nees) Ensermu, Hieracium murorum L., Hieracium pilosella L., Hieracium praealtum Vill. ex Gochnat, Chromolaena odorata (L.) R.M.King & H.Rob., Mikania micrantha Kunth, Croton hirtus L'Her., Limnocharis flava (L.) Buchenau, Clidemia hirta (L.) D.Don, Miconia calvescens DC, and Nassella charruana (Arechav.) Barkworth. Most of these species appear to have been present for several to many years before they were detected and some now occupy areas that make eradication less feasible than if the species hadbeen detected earlier. Early recognition of new invaders is essential for cost-effective intervention. We suggest that an increased detection effort should initially target areas around population centres as this is where most weeds first appear.

Anderson亚数据。 Micrantha（NEES）Ensermu，Hieracium Murorum L.，Hieracium Pilosella L.，Hieracium Praealtum Vill。 ex gochnat，Chromolaena Odorata（L.）RMKing＆H.Rob。，Mikania Micrantha Kunth，Croton Hirva L'她。，Limnocharis Flava（L.）Buchenau，Clidemia Hirta（L.）D.don，Miconia Calvescens DC，和Nassella charruana（arechav。）barkworth。大多数这些物种似乎在检测到它们之前几到多年来一直存在，并且现在有些占据了不可行的区域，而不是在早些时候检测到的物种。早期认识到新入侵者对于具有成本效益的干预至关重要。我们建议增加的检测努力应最初的目标地区，因为这是大多数杂草首次出现的地方。
