delayed by lengthy assessments of such aspects – rather, as soon as a new
incursion of a non-authorised alien species is detected, the eradication should
be promptly started.
To facilitate prompt reaction to invasions, it is important to increase the
ability to detect new alien species through an early warning system, focused
on most harmful species and most vulnerable areas. Early warning systems,
focusing especially on key areas, should be set up, also based on lists of most
dangerous alien species.Also, the competent authorities should establish contingency
plans for eradicating specific taxa or groups with similar characteristics
(e.g. plants, invertebrates, marine organisms, freshwater organisms,
freshwater fishes, reptiles, amphibians, birds, small mammals, large mammals).
Information management is particularly critical for reducing the time
lag before a new invasion is detected and, for this reason, it is important to set
up mechanisms for collecting and circulating information, including identification
keys for different taxonomic groups but also references to experts for
the various taxa, control methods, etc.
The authorisation process should be streamlined, in order to allow rapid
response; where urgent eradication action is needed, the use of emergency
orders should be considered. Competent authorities should be equipped in
advance with powers to take appropriate mitigation measures. The founding
of a national coordination body should be considered, and adequate funds
and equipment for rapid response to new invasions should be secured. Relevant
staff should be trained to use the eradication methods (see also Chap.
21).
22.3.3 Planning the Eradication of Established Populations
Eradications of long-established alien species require proper planning, based
on an assessment of key biological, technical and economical aspects, and the
involved human dimensions. In many cases, public information and awareness
are critical, and the development of specific education programs or public
awareness campaigns should be considered. Participation of local communities
should be encouraged, and relevant societal sectors (hunters, NGOs,
foresters, landowners, fishermen, etc.) should be engaged in the eradication
programs whenever possible.
22.3.4 Legal-Organizational Aspects
National legislation and local regulatory tools should be reviewed to ensure
that the legal status of alien species is compatible with control measures, and
that the roles and competencies of the relevant authorities are clearly defined.
In order to improve coordination and reduce the time for initiating the
