This collection of case studies illustrates the role

of taxonomy in Invasive Alien Species (IAS) management.

With examples from various sectors, the case studies

highlight how taxonomic expertise, surveys, information

and analysis are of crucial importance to recognising

and solving ecological, agricultural, trade, health and other

problems caused by IAS.  

Taxonomy is a critical tool for combating the threat

from IAS.  Without access to expert support,

misidentifications are made, costing money and

time when rapid decisions need to be made, for

example at border posts and regulatory agencies.

Only when a suspected IAS is correctly identified can

effective control or mitigation measures be implemented,

drawing where possible on best practice learnt from

tackling the IAS elsewhere.  Prompt and reliable

identifications, supported by networking that promotes

the sharing of experiences, information and expertise,

may eliminate the need for costly eradication

programmes.  Where elimination programmes are needed,

taxonomists help to develop the most environmentally

benign, economic yet effective methods. 

Taxonomic knowledge and skills are at the centre of

anti-IAS measures.  Expertise needs to be mobilised

and shared.  Taxonomic capacities need to be accessible

to all countries to support the prompt identification and

monitoring of IAS threats and delivery of control

programmes.  Capacity is being developed but

significant further investment is required.  Is this

difficult to justify when the benefits far outweigh

the costs at ratios such as 50:1?
