Progress

Reindeer are found only in East Iceland, divided into nine reindeer hunting areas (see Figure 1) and further divided into counting areas (see Figure 2). Snæfellsherd is the group of reindeer that spend the summer in the vicinity of the mountain Snæfell east and Hálslón reservoir. Snæfellsherd further splits into two sub herds: Norðurheiðaherd, located west and north of Jökulsá á Dal river and Hálslón reservoir (in hunting area 1), and Fljótsdalsherd, located east of the river (in hunting area 2). The status of Snæfellsherd is discussed here. The condition of the reindeer population in East Iceland is discussed in more detail in annual monitoring reports (Icelandic only) by the East Iceland Nature Research Centre (Náttúrustofa Austurlands).

Figure 3. An average of 3 years intervals of numbers of reindeers in Snæfell's herd based on counting during summer 1965-2020. The revised number north of Snæfellsöræfi wilderness and Jökuldalur valley is mainly based on counting in the breeding season after the year 2009.

Changes in the number of reindeer in Snæfellsherd since 1965:

  1. 1965-1976. Increase, the peak reached 1972 - 1976 (almost 3600 animals), no hunting 1965-1967 and 1970-1971.
  2. 1977-1984. Migration causes reduction, presumably due to herd migration to the fjords.
  3. 1985-1999. The number of animals is low (fluctuating between 1000-1500).
  4. 2000-2007. Increase until 2007, intentional reduction by hunting.
  5. 2008 - 2020. Expansion to the east and north causes a decrease in summer counts in traditional areas in Snæfellsöræfi. The animals disappear from Kringilsárrani and Sauðárrani (Norðurheiðaherd). The number of animals in Fljótsdalsherd increased, especially in Vesturöræfi, but numbers in that area have come down again in recent years.
  6. 2021. The decrease is thought to be due to increased migration of animals between hunting areas and possible overestimation in previous years.

In the summer of 2021, about the same amount of animals was found and counted in Snæfellsherd as the year before. The main change was at Fljótsdalsherd; fewer reindeer were in Vesturöræfi (75 versus 284 in 2020) but more in Austurheiði (528 versus 328 in 2020). From Norðurheiðaherd, only 86 animals were found west of Jökla in Kringilsár- and Sauðárrani, but at the time of breeding, there were 163 animals. A large part of the Norðurheiðaherd now spends the summer in the northernmost part of the reindeer distribution area towards Bakkafjörður, and only a few animals have been seen in the summer census in recent years. The total number of reindeer west and north of the river Jökulsá á Dal, in Kringilsárrani, Sauðárrani and in Norðurheiðar during the summer is about 1000 animals. Due to the difficulty of finding the animals in Norðurheiðar in July, the numbers are also partly based on counts during the rutting time and information from hunters and locals. Fluctuations in the numbers of reindeer east of the Hálslón Reservoir are explained by the fact that reindeer from Snæfellsöræfi sometimes roam further east of their traditional summer pastures and do not always show up in the July count of Snæfellsherd.

The distribution and number of animals in Snæfellsöræfi during the summer has changed since 2000 when the main summer pastures moved from Vesturöræfi to Fljótsdalsheiði and ten years later to the nearby hunting area (areas 6 and 7). In 2000, the animals at Snæfellsöræfi were 1896, but in 2021 they were 414 (Table 1). Since 2014, the number of animals in Vesturöræfi began to increase again. The decrease in 2021 is opposed to the development over the recent years and has reduced hopes that Vesturöræfi was gaining its former place as the main summer pasture for Fljótsdalsherd.

The overall result is that the number of animals in Snæfellsherd fluctuates between years. West of the river Jökulsá á Dal, in Kringilsrárrani and Sauðárrani, they have almost disappeared.

The Engineering Research Institute of the University of Iceland was responsible for counting reindeer for Landsvirkjun from the air during the calving season north of the Brúarjökull glacier from 1993 until 2013 (See report from 2013: LV-2013/127 (Icelandic only)).

Since 2005, the East Iceland Nature Research Centre has monitored reindeer calving areas in the vicinity of the Kárahnjúkar hydropower construction area. During the first years, monitoring was carried out from land but in recent years, from the air.

In 2015, a report was published summarising data collected in calving areas over nine years (2005-2013) LV-2015/130 (Icelandic only), and in 2021, a report (Icelandic only) was published presenting the results of research from 2005-2020. The study revealed that fewer and fewer animals have lived in formerly known breeding areas closest to reservoirs, power plants, and other associated structures since 2009. In 2020, only 12% of the estimated number of cows were found in hunting area 2 in the breeding studies. The cows that remained in hunting area 2 in the spring of 2014-2020 seemed to be moving closer to the power plant structures in Vesturöræfi, but only in the rather snowy spring. The low calf ratios in July in hunting area 2 in the last years of the study (2018-2020) were a cause for concern, and it could not be ruled out that it was related to poorer access for purebred cows to good breeding areas. The fact that the lightest part of Vesturöræfi went under a reservoir could have made Vesturöræfi a more homogeneous option and are therefore probably not as suitable for carrying as before. It is also unclear what effect increased access to the area has had in connection with the power plant project. Still, the gestation period is when the cows are most vulnerable to disturbance, access to food is most limited, and calves are at a particularly sensitive level. When disturbing the bearing area of ​​a small population, an effect must be expected, although such an effect may take some time to develop. It is unclear where most cows from hunting area 2 have been in recent years, but it is important to understand this better.

In 2021, breeding areas were mapped again, and about 22% of cows were found in hunting area 2. It seems that the Fljótsdals-cow (cows that live in hunting area 2 in the summer) are, to some extent, outside that hunting area.

Research on the distribution and grazing of reindeer in Snæfellsherd with GPS transmitters began in 2009 after the Kárahnjúkar power plant began operations. The first animals were tagged in 2009. Research on reindeer with GPS devices in 2009-2011 was published in the autumn of 2014 NA-140140 (Icelandic only). In connection with load-bearing research from 2014 to 2020, six new transmitters were installed on purebred cows in Snæfellsherd in 2017-2020. The results of those studies were published in the report mentioned above.

In recent years Landsvirkjun and the East Iceland Nature Research Centre have been adjusting the monitoring of vegetation and reindeer with increased emphasis on the integration of reindeer and vegetation studies, including the potential impact of the significant increase in the pink-footed goose in the area around Kárahnjúkar.

Metrics, Targets and Monitoring Protocol

What is measured?

The number of reindeer and distribution of Snæfellsherd especially in Snæfellsöræfi wilderness i.e. Brúaröræfi wilderness, Vesturöræfi wilderness, Under Fellum, Múli and Hraun and Norðurheiðar (Impact of hydropower projects considered undirect in the latter two).

Monitoring Protocol

Direct counting and aerial photos taken in the first two weeks in July each summer are used to estimate the number of animals.

Targets

Not more than 15% decrease in the reindeer stock in Vesturöræfi wilderness, Múli and Hraun east of Snæfell mountain.

Possible countermeasures

Not applicable, monitoring only.

 

Changes of indicator

This indicator was originally number 24.2. It was then named Reindeer and can be found under that number in the project documents from 2005 and 2006.

The indicator number has been changed twice.

2007 2.23 Reindeer

Baseline

The distribution and composition of Snæfellsherd have been monitored over the summer since 1965 with counts from an aircraft in the first two weeks of July (Figures 3 and 4). The number of animals increased from 1965 and peaked in 1972 and 1976, or over 3,500 animals. Over the next ten years, their number halved and remained steady until 2000. For the next six years, the number of animals in Snæfellherd increased to almost 3,000, and at the same time, they mostly roamed Fljótsdalsheiði instead of Vesturöræfi, which had been their main summer grazing land. After 2006, the number of animals from the Snæfellsherd, east of Hálslón.

Part of the Snæfellsherd roams west of Hálslón during the summer countings, i.e., in Kringilsárrani and Sauðárrani. There was an average of 230 animals from 1987 to 1999 and 220 from 2000 to 2012. In 2007 the adult bucks no longer came to Kringilsárrani as they had done during the ten years before.

Rationale for Indicator Selection

Kárahnjúkvirkjun power plant will have some effects on reindeer habitats but it is not clear if the project will influence the size of the stock or only change reindeer migration patterns. Reindeer were imported to Iceland late in the 17th century. They are important to East Icelanders because they generate income from hunting licenses. Also, reindeer are beautiful animals and characteristics of the area.

It is expected that the Kárahnjúkavirkjun power plant will affect reindeer habitats due to land inundated by the Hálslón reservoir and reservoirs in Múli and Hraun. Reindeer have historically calved in Háls which was inundated by Hálslón reservoir. Furthermore, it was expected that increased human activity in the previously pristine area would disturb the animals and cause changes to the spring and autumn migration of reindeer across the river Jökulsá á Dal. Landsvirkjun power plant sponsors research on the migration patterns of reindeer, both on animals belonging to the Snæfellsherd and animals in closeby herds in the fjords. Jökulsá á Dal river ran through the middle of where Hálslón reservoir is located. About 19 km2 of vegetated land east of the river and 13km2 west of the river was inundated by Hálslón reservoir. A total of 6 km2 of vegetated land was inundated by smaller reservoirs in Múli and Hraun.

NA-220226 - Vöktun hreindýra 2021 og tillaga um veiðikvóta og ágangssvæði 2022

2022

Náttúrustofa Austurlands leggur til að veiðikvóti ársins 2022 verði 1021 hreindýr; 546 kýr og 475 tarfar sem er 199 dýrum færra en í fyrra. Jafnframt er lagt til að mörk veiði- og ágangssvæða verði óbreytt og að eins og fyrri ár verði kúaveiði heimiluð í nóvember á svæðum 8 og 9 og skara megi kúaveiði milli þessara svæða ef þörf þykir. Lögð er til sú breyting að tarfaveiði á svæði 9 hefjist 15. júní til að minnka líkur þess að hreindýr fari vestur fyrir Breiðamerkurlón svo og að draga úr gróðurskemmdum af völdum hreindýra á Breiðamerkursandi. Eins og fyrr er lagt til að kálfar og veturgamlir tarfar verði friðaðir.

Gerð er grein fyrir vöktun hreindýrastofnsins 2021 og forsendum sem liggja til grundvallar kvótatillögum skýrðar. Líkamlegt ástand dýra er metið út frá upplýsingum um  allþunga og bakfitu veiddra dýra árið 2021, en eins og fyrri ár er ljóst að auka þarf mælingar á bakfitu og fallþunga á dýrum veiddum á svæðum 8 og 9. Gerð er grein fyrir þéttleika dýra að vetri. Stærð og hlutfallsleg skipting hreindýrahaga eftir ástandi lands er sýnd eftir veiðisvæðum. Fjallað er um frjósemi, fjölda dýra og nýliðun, auk þess sem aldurs- og kynjahlutfall er skoðað. Einnig er gerð grein fyrir burðarvöktun hreindýra á Snæfellsöræfum 2021. 20 kýr voru með virka senda á árinu en einungis 12 eftir í árslok. Stefnt er að því að endurheimta rafmagnslausa kraga og fjölga kúm með virka senda, einkum á svæðum 2, 6 og 7.
