Costs of biological invasions in Europe

2009-11-12

A report discussing options for developing a European policy on invasive species has been just posted on the European Commission webpage. The report also includes an estimate of the costs caused by invasives to the European economy. This cost is roughly estimated at 12 billion € per year.

No closed season for American mink, Raccoon dog and Raccoon

2009-10-27

According to the new decree of the Minister of Environment issued on 22 September 2009, hunting American mink, Raccoon dog and Raccoon is possible throughout the year. Previously these invasive alien species enjoyed closed season allowing them to breed. The new regulation will hopefully help to reduce population numbers of these species.

New record of Rudy duck in Poland

2009-10-26

One specimen of Ruddy duck Oxyura jamaicenis was recorded between 25.10.-8.11.2009, in the complex of fishponds in Łężczok (S Poland; BirdWatching.pl). Due to hybridisation, this species is the main threat to the long-term survival of the globally threatened European White-headed duck O. leucocephala.

In order to protect the native species, a pan-European project of Ruddy duck eradication was launched a few years ago. In Great Britain alone this programme, fully supported by the Royal Society for the Protection of Birds (RSPB), resulted in shooting more than 6,100 Ruddy ducks since 1995. Also Recommendations 124 (2007) and 61 (1997) by the Bern Convention urge Parties to control that species. Apart from Great Britain, shooting is also carried out in Spain and France, and is considered in the Netherlands. Poland, as a Party to the Bern Convention, should also join these efforts, even though the Ruddy duck is not invasive here: it has been recorded only exceptionally and it does not affect the White-headed duck here, as there is no breeding population of this species in Poland. This makes the Ruddy duck an attractive rarity for many birdwatchers.

In addition, control of the species in Poland could be difficult, as its legal status is not clear (it is not on the hunting species list).

Muscovy duck breeding in the wild in Poland

2009-09-23

On 20.09.2009, in the complex of fishponds Stawy Milickie in the Barycz river valley (SW Poland) a pair of Muscovy ducks Cairina moschata with 14 ducklings were recorded (BirdWatching.pl). This duck is one of the most common poultry species in Poland but its breeding in the wild had not been previously recorded. The reported records suggests that Poland may join several other European states where wild populations of this species are found (DAISIE, NOBANIS).

NOBANIS meeting in Kraków

2009-09-16

The NOBANIS group will meet in Krakow between 24-25 September. NOBANIS (European Network on Invasive Alien Species) has developed a network of common databases on alien and invasive species in 18 countries of central and northern Europe. Polish data are provided by the „Alien Species in Poland” database.

Invasive Alien Species designated on the theme of International Biodiversity Day

2009-05-13

In order to raise awareness of biological invasions, the Convention on Biological Diversity chose Invasive Alien Species as the main theme of the International Biodiversity Day. On May 22, conferences, lectures, exhibitions and other activities will be organised worldwide to inform on threats from biological invasions and on ways to solve this problems.

New portal Alien Species in Poland

2009-02-26

After the long period of preparation, we are launching a new portal Alien Species in Poland. The database remains its main element. The database structure was significalny changed to comply with guidelines developed by GISIN (Global Invasive Species Information Network; www.gisinetwork.org).

The level of detail in species accounts in the database ranges from mere speciesname, to comprehensive datasheets. Some information is only available in Polish at the moment - it will be translated into English soon. In future, new alien species will be added to the database and data concerning the species already recorded will be updated. We have made every effort to check the accuracy of the data. However, we are aware that there are mistakes and inconsistencies that were not avoided. Therefore please send any questions you might have and any comments concerning the database.
