Italienske grottere gir råd om WNS
« p: 31.01.2010 15:34 »
Det italienske grotteforbundet har utarbeidet følgende råd for å forebygge WNS

WNS: what shall we do?
In the Unite States of America, bat populations are currently under a serious microbiological threat, the White Nose Syndrome, which cause, pathology and transmission processes are still poorly understood. It is widely known that the transportation of diseases between continents could produce severe consequences on human beings as well as animal and vegetation populations, that often behave as no-adapted organisms for a specific disease. The smallpox or the measles, that decimated the American Natives in the 16th Century, and the spreading of the Plasmopara viticola, the causal agent of grapevine downy mildew, accidentally introduced in Europe from North America, represent some examples.
These are the reasons why the import/export of biological products (mainly soils and composts) from remote Countries is widely forbidden. In the specific case of the WNS, which is severely affecting the American bat populations, one of the explored hypothesis is to consider it as an originally Eurasian disease that has found a particularly fertile environment for spreading among US bat population.
Many US research groups are currently involved in studying this phenomenon. To know more about biological pollution refer to (hyperlink).
How shall we behave?
The WNS is still poorly understood, as yet some basic suggestion on preventive measure to adopt, not only for limiting the WNS dissemination but also to prevent the microbiological pollution process, are given below. Underground contests represent ecological niches hosting particular life forms. The understanding of the underground microbiology is still at an early stage of knowledge yet evolving to a increasing level of scientific and operative interest. It is, therefore, very important for cavers to be aware of – and limit as much as possible - the key role they play as agents of microbiological transportation between ecological niches.
During ordinary caving:
1) follow the compulsory direction given by local authorities in accessing bats wintering and/or nursery caves; 2) categorically limit the access to caves where bats inhabit, especially during winter time when the transmission of WNS occurs.
3) carefully clean and/or sterilise all equipment used in a cave, prior to and following each use, mainly and especially when visiting different karstic areas.
If you find dead bats that show the symptoms of WNS:
1) please follow carefully the guidelines suggested by the GIRC (hyperlink); the Italian version of the US Fish and Wildlife Service guidelines are available here (hyperlink). 2) report immediately the finding of dead bats to Societ  Speleologica Italiana (SSI), mailing to; the SSI is working with bat scientists in order to create the map of Italian caves under potential risk of WNS.

"When I try to imagine a faultless love
Or the life to come, what I hear is the murmur
Of underground streams, what I see is a limestone landscape."
W.H. Auden, "In Praise of Limestone"
