Parliamentary question of 5th September 2019 regarding the European list of invasive alien species

On 5 September 2019, Mars Di Bartolomeo, Member of the Chamber of Deputies, addressed a parliamentary question to the Minister of the Environment regarding the European list of invasive alien species.

Question 1

Which species on this list have been recorded in Luxembourg?

Response from Carole Dieschbourg, Minister for the Environment, Climate and Sustainable Development:

Plants (5 species):

  1. Tree of heaven (Ailanthus altissima)
  2. Himalayan balsam (Impatiens glandulifera)
  3. Giant Hogweed (Heracleum mantegazzianum)
  4. Nuttall’s waterweed (Elodea nuttallii)
  5. Parrot’s feather (Myriophylum aquaticum)

Animals (9 species):

  1. Spiny-cheek crayfish (Orconectes limosus)
  2. Signal crayfish (Pacifastacus leniusculus)
  3. Topmouth gudgeon (Pseudorasbora parva)
  4. Egyptian goose (Alopochen aegyptiacus)
  5. Pumpkinseed (Lepomis gibbosus)
  6. Coypu (Myocastor coypus)
  7. Muskrat (Ondatra zibethicus)
  8. Raccoon (Procyon lotor)
  9. Red eared slider (Trachemys scripta).

Question 2

Given that these species pose a threat to biodiversity and ecosystem services, what is his Ministry’s strategy for more effective eradication, management and control methods to combat the adverse effects associated with this phenomenon?

Response from Carole Dieschbourg, Minister for the Environment, Climate and Sustainable Development:

In accordance with European regulations, Luxembourg’s strategy to counter the environmental and social problems caused by invasive alien species has four main components, namely

  1. prevention,
  2. early detection and rapid eradication,
  3. management,
  4. awareness and training.

There are two scenarios:

  1. the establishment of emerging species and any new invasive alien species detected on national territory is prevented;
  2. populations of widely distributed species are controlled, in order to reduce their environmental and social impacts and avoid further spread.

For widespread species, “Invasive Alien Species Action Plans” have been developed, which include the actions to be implemented for each species. All actions thus defined shall be based on the best scientific knowledge and shall take due account of cost-effectiveness, human health, the environment and animal welfare.

A public consultation will be launched shortly for each action plan.

Asclepias syriaca L. originates from North America and is cultivated as an ornamental. It was introduced into European countries from France to Bulgaria and Russia (potentially invasive) (EPPO 2019). A. syriaca colonises a variety of communities from woodlands to cleared grasslands and marshlands. It grows in clumps or patches in meadows, fencerows, roadsides, railways, waste places, reduced-tillage fields, and other open habitats (CABI 2010). Larger populations can displace native plant and animal species, especially if the species penetrates into habitats worthy of protection. The large leaves shade the soil and thus prevent the emergence of other species (Anonymous 2014).

In 2014, Switzerland added Asclepias syriaca L. to its List of Invasive Alien Plants (EPPO 2019, Anonymous 2014).

IAS of Union concern

In 2017, Asclepias syriaca L. was added to the list of invasive alien species of Union concern (Anonymous 2017) which implies that member states shall take all necessary steps to prevent it’s unintentional introduction or spread.

Status and distribution in Luxembourg

Asclepias syriaca L. has not yet been observed in Luxembourg.

First record of Solanum rostratum in Luxembourg

Solanum rostratum Dunal was first observed in the wild in Luxembourg on 21 August 2019 by Jörg Zoldan and Annette Steinbach-Zoldan on the border of a maize field in the municipality of Kayl (Southern part of Luxembourg), during a field study on behalf of SICONA.

Description

Solanum rostratum Dunal (spiny or prickly nightshade, Mexican thistle) is a species of nightshade that is native to the US and northern and central Mexico. It is an annual, self-compatible herb that forms a tumbleweed and has abundant spines on the stems and leaves. In its native range S. rostratum is pollinated by medium- to large-sized bees including bumblebees. The seeds are released when the berries dry and dehisce (split apart) while still attached to the plant (Wikipedia contributors 2019).

This species represents one of the later scientific interests of famed biologist Charles Darwin, who just over a week prior to his death had ordered seeds from a colleague in America, so as to investigate their heteranthery, a topic he was interested in (Wikipedia contributors 2019).

Solanum rostratum is the ancestral host plant of the Colorado potato beetle, Leptinotarsa decemlineata, but this pest adopted the potato, Solanum tuberosum as a new (and more succulent) host, a fact first reported in eastern Nebraska in 1859. It then expanded its range rapidly eastward on potato crops in the next two decades (Wikipedia contributors 2019).

Solanum rostratum as an invasive alien weed

Solanum rostratum is a taprooted annual plant known to be a noxious weed in parts of the USA and Canada, and is included in the Global Compendium of Weeds as an ‘agricultural weed’, ‘casual alien’, ‘environmental weed’, ‘naturalised’, ‘noxious weed’, and ‘weed’ across tropical and temperate regions of the world. It is a fast-growing, vigorous weed native to Mexico and the United States and now widely introduced including into Asia, Oceania and Europe (Austria, Bulgaria, Denmark, Germany, Hungary, Moldova, Russia, Slovakia, UK, Ukraine). The species invades ecosystems by forming dense colonies, and a single plant can produce hundreds of seeds which are dispersed by both biotic and abiotic vectors, as well as self-propelled by its dehiscent fruit (Datiles & Acevedo-Rodríguez 2014).

Brief description

Lysichiton americanus Hultén & H. St. John grows in the transition zone of terrestrial, semi-aquatic and aquatic habitats like swamps, fens, wet meadows, marshy and alluvial woodlands, along streams, riverbanks, lakesides and ponds. It has no specific site condition requirements except the presence of saturated organic soils. It is often found in protected semi-natural habitats. Lysichiton reproduces almost exclusively by seeds, which may be dispersed downstream along waterways. However, spread by natural means is not frequent and rather limited. L. americanus has become established locally in swamp forests and associated wetlands in the EPPO region (resulting most of the time from plantation in the site). After some years, its huge leaves build a dense layer excluding light from native species which are usually not adapted to extreme darkness. It can displace and cause local extinction of rare species of mosses and vascular plants (Carex echinata, Viola palustris, and orchids). (Branquart et al. 2010).

IAS of Union concern

In 2016, Lysichiton americanus Hultén & H. St. John was added to the list of invasive alien species of Union concern (Anonymous 2016) which implies that member states shall take all necessary steps to prevent it’s unintentional introduction or spread.

Status and distribution in Luxembourg

Lysichiton americanus Hultén & H. St. John has not yet been observed in Luxembourg.
