Further comments on relative priority and on availability of resources
In general, most Belgian legislative tools are related to plant health
regulation (crop protection). Few measures explicitly consider the issue of
alien invasive species as a threat for natural ecosystems, even if coastal and
freshwater habitats begin to be invaded by numerous exotic species. In the
national strategy (publication foreseen for 2002), alien species will be
specifically addressed and integrated in plans for the concerned sectors. For
Flanders, the resolution of the Flemish Executive concerning the introduction
of non-indigenous species (31.07.1993) inhibits any intentional release of
animal species at places where escapes into nature may be expected. The Nature
Conservation Decree (21.10.1997) aims at an enhancement of the native fauna
and flora, and the protection of plant and animal species and their habitat
communities. Together with the 'stand-still' principle, this also assumes the
counteraction of the invasion of alien species. For Wallonia, the resolution
of the Walloon Government regulating the release of non indigenous animal
species in the wild and the introduction of these species in game reserves
(29.11.1990) foresees a.o. a permit system and a compulsory assessment of the
impacts of the non indigenous species on indigenous fauna and nature, and an
evaluation of the risks that the species would spread to adjacent areas. No
introductions may harm the local fauna and flora. For the moment, the
applicability of this resolution is uncertain due to the lack of a list of
indigenous species in Wallonia.
88. Has your country identified alien species introduced?
b) only major species of concern
c) only new or recent introductions Br. / Wa.
d) a comprehensive system tracks new introductions
e) a comprehensive system tracks all known introductions Fl.
(88) Flanders:- Flora. A database is being developed for higher
plants in Flanders. It will contain all recently introduced species (after
'72). For the established plants, there is an extensive list of all species.
This list also contains species introduced before 1972. There is active
eradication of the cherry (Prunus serotina) in some parts of Flanders,
leading to good results i.a. in the Kempen.- Breeding birds. There is a
program in which rare, colonial and introduced breeding bird species are being
monitored. Among them, alien breeding bird species as the white fronted goose
(Anser erythropus), the Canada goose (Branta canadensis), the
barnacle goose (Branta leucopsis), the Nile goose (Alopochen
aegyptiacus), the mandarin duck (Aix galericulata), the ring-necked
parakeet (Psittacula krameri) and the monk parakeet (Myiopsitta
monachus) are being monitored. This program is called the 'Bijzondere
Broedvogels Vlaanderen Project' (Flemish Special Breeding Bird Project).-
Mammals. The Asiatic ground squirrel (Eutamias sibiricus) and the coypu
(Myocastor coypus) are studied to investigate the necessity of
monitoring. There is active eradication for the muskrat (Ondatra zibethicus)
because this species is known to provoke serious harm to waterways. - Fish.
Through the monitoring and inventory of fish occurring in the Flemish inland
waters, alien fish species are also being monitored.
(88) Wallonia - Alien species are identified through inventories of
species for some groups (e.g. mosses and liverworts, vascular plants,
crustaceans, birds, mammals). The Nature, Forest and Woods Research Centre is
currently monitoring invasive species in the Walloon watercourses.
(88) An example of the identification of introduced alien species is
provided by the National Botanic Garden of Belgium which has documented the
spread of some alien invasive species. Special attention has been given to
some bryophytes (e.g. Lophocolea semiteres) and to invasive C4 grasses
(e.g. Setaria macrocarpa, S. verticilliformis, Panicum
dichotomiflorum) in the weed communities of maize-fields in Flanders.
89. Has your country assessed the risks posed to ecosystems, habitats or
species by the introduction of these alien species?
b) only some alien species of concern have been assessed X
c) most alien species have been assessed
90. Has your country undertaken measures to prevent the introduction of,
control or eradicate those alien species which threaten ecosystems, habitats
a) no measures
b) some measures in place X
c) potential measures under review
d) comprehensive measures in place
(90) The Belgian law of 20 January 1999 on the protection of the marine
environment in marine areas under Belgian jurisdiction (MMM law) forbids the
intentional introduction of non indigenous species in the marine environment
without special license (Art. 11, §1). This provision mirrors those included
in international instruments like the CBD. The unintentional introduction of
non indigenous species via ballast water of ships can be prohibited by royal
decree (Art. 11, §2). Due to the specific and international character of the
issue of non indigenous species in ballast water of ships, however the new
Belgian framework law did not specifically touch this issue, and this activity
is to be regulated by an implementation decree. For the protection of the
marine biota, measures can be taken (by royal decree and after scientific
consultation) for the extermination of non indigenous nuisance species (Art.
11, §3). The new law also prohibits the intentional introduction of
genetically modified organisms into marine areas (Art. 11, §4).
Decision IV/1 Report and recommendations of the third meeting of SBSTTA
91. Is your country collaborating in the development of projects at
national, regional, sub-regional and international levels to address the issue
of alien species?
a) little or no action
b) discussion on potential projects under way Wa.
c) active development of new projects Fl.
(91) The Walloon Region finances the activities of the Secretariat
of the Bern Convention, regarding alien species.
(91) GISP made a call for action to be part of the extended collaborative
information exchange system on invasive alien species. The Belgian National
Focal Point has submitted the form and will act as the national focal point
for this programme. Moreover, the Belgian NFP, in co-operation with the
Flemish Region (AMINAL), is currently working on the establishment of a
contact group on alien species that will operate under the authority of the
Steering Committee 'Biodiversity Convention'. This contact group will address,
among others, the issues of inventory, monitoring, reporting and legislation.
There are a few individual initiatives from scientists, who take part in
international research programmes dealing with invasive organisms. Belgium,
through the Belgian Biodiversity Platform, participated to the Montpellier
EPBRS meeting on alien species (2000).

b) yes - limited extent X
c) yes - significant extent
(92) The alien species issue (invasion mechanism understanding, impact
assessment methods, etc.) is part of the research priorities of the Second
Plan for a Sustainable Research Programme (2000-2004) of the Federal Office
for Scientific, Technical and Cultural Affairs, both on terrestrial ecosystems
(one project: 'invasion and biodiversity in grasslands and field borders') and
on marine and freshwater ecosystems. URL: www.belspo.be
(92) Flanders - Action 117 under the theme 'Loss of biodiversity' in
the Environmental Policy and Nature Development Plan 1997-2001 (MINA-Plan 2)
implies the elaboration of a framework to consider the desirability of
(re-)introduction of species and to avoid unwanted (re-)introductions. This
also implies taking into account the genetic diversity within species in case
of (re-)introduction and considering the consequences of the use of GMOs on
local biodiversity. The Institute for Forestry and Game Management is
currently developing a documented database of the non-native fish species of
Flanders, which may be used in the future as a reference system for
information on the occurrence and the ecology of non indigenous fish species
