![]() In the last few weeks, the world could hardly have failed to have heard about the Icelandic volcano with the difficult to pronounce (for non Icelandic speakers) name. Air traffic has been disrupted across Europe and airlines have lost over a billion dollars in lost revenue. The impact on the regions climate is unclear but has been the topic of much speculation. Latest information received from the Icelandic Meteorological Office indicates that the explosive activity from the Eyjafjallajökull volcano is continuing, with the ash plume reaching heights of up to around 18,000 ft. The Icelandic Met Office state that there are no signs that the eruption is about to end, with the volcanic eruption remaining dynamic. Winds are expected to blow from a mainly north or north easterly direction over the next few days, with most of the ash cloud likely to stay over the Atlantic Ocean and close to western parts of the British Isles. As a result the UK National Air Traffic Services continues to advise aircraft about airspace restrictions affecting transatlantic flights, allowing them to cross the Atlantic safely. Recent weather patterns mean that the ash cloud has drifted across some parts of central and southern Europe, leading to disruption. Icelandic farmers in the immediate vicinity of the eruption have lost their livelihoods for perhaps many years. However, the world has not heard a lot about the fate of Iceland's reindeer. Reindeer husbandry and herding is not practiced in Iceland. The Icelandic population today derives from 35 animals that were set ashore in the north east of Iceland in 1787. The reindeer were brought from Finnmark, Norway, to four different areas in Iceland in the late 18th century but three of the herds had disappeared or died out before 1930. The Norwegian animals were of semi-domesticated origin but have always been feral in Iceland. The present day population is confined to East Iceland. The population is increasing although 20-25% of the total summer population is hunted annually. The estimated winter population in 2008-2009 is 5200 animals and expected to be around 6500 in autumn 2009. Map adapted from the CARMA website The Reindeer Portal contacted the national expert on reindeer in Iceland, Skarphéðinn G. Þórisson of the Náttúrustofa Austurlands (East Iceland Natural History Institute), in Egilsstadir. Þórisson has been working and researching reindeer in Iceland since 1978. Þórisson is reponsible for herd monitoring and population estimates. According to Þórisson, "Ash has not fallen on the reindeer pastures and the predominately south westerly winds have protected the pastures. In fact there is hardly any ash falling on Eastern Iceland...If we would have a major ash fall in the reindeer pastures I think there are mainly two things we have to worry about. Firstly the content of fluor in the ash and secondly the thickness of the ash layer." Þórisson pointed out that in the historical context, this is not a large eruption, "In 1875, there was a much larger eruption - a large explosion in the interior. Then there was a lot of ash - as much as 10-20 cms fell on the country and reindeer pastures. That explosion forced a large out migration of Icelanders to North America. Then there was no lava, and strong westerly winds, yet I have not been able to find out about any impact on the reindeer from that time. The ash particles coming from the eruption in Eyjafjallajökull now is most likely much smaller (down to 10 micrometers) than in the eruption 1875" Þórisson has inspected parts of the reindeer pastures (some ca. 15,000 kms2 in Iceland) and has seen no evidence of ash falling on the pastures, nor when using a white trapping surface has he seen much evidence of ash fallout. Should the ruption expand, or winds change direction, he noted that the situation could change quite quickly. The Norwegian Meteorological Institute have created some animated clip of the movement of the ash, which you can see here. One thing that has certainly changed according to Þórisson is the winter temperature trends over the last 10-15 years and the noticeable lack of hard winters. This has certainly been beneficial for the reindeer in terms of survival and body weight (Reindeer in Iceland have no predators). It has also reduced the movement of animals. The population is increasing although 20-25% of the total summer population is hunted annually. The estimated winter population in 2008-2009 is 5200 animals and expected to be around 6500 in autumn 2009. Current prices of a hunting card for an adult male is ca. 120,000 ISK (740EURO/ 930USD) and 60,000 ISK for an adult female. Photo from na.is Related Articles/Posts Iceland, Reindeer, Volcano |
