Practical Management of Invasive Non-Native Weeds in Britain and Ireland

This manual, aimed at professionals involved in dealing with invasive weed species, brings together for the first time essential information required to manage non-native invasive plants.

Advice involves immediate ‘rapid-response’ actions to initiate containment along with preventative strategies, measures for control and monitoring requirements post-control. The manual responds to the GB Non-Native Species Strategy and deals with over 40 species which have been selected from plants listed in Schedule 9 of the Wildlife & Countryside Act 1981 (as amended) for the UK; invasive alien species of EU concern (as per EU IAS Regulation 1143/2014); and other noteworthy species of the urban environment, for example butterfly-bush (buddleia).

Each species account includes: a brief description on ecology and identification with corresponding photographs; a distribution map for the British and Irish Isles; immediate actions that can be taken once identified; pathways of spread; lifespan; seed-production age; seed longevity; growth rate; a ‘schematic’ of the life-cycle aimed at assisting the determination of schedules for survey and treatment; prevention and rapid-response measures; tables of control, management and herbicide treatment linked to decision-making flow diagrams; waste-disposal requirements; revegetation post-management; and continued monitoring. Key references to published data and links to appropriate websites are also included.

The manual has been compiled for the Property Care Association (PCA) from information supplied by members of its Invasive Species Control Group.
