2.7 Extent of Wilderness

Indicator 2.7 - Extent of Wilderness


2.7 NorðurdalurThe landscape and visual impact of the Kárahnjúkar power project was an issue discussed in the environmental impact assessment. This included the loss of wilderness caused by the project.    Here we monitor loss of wilderness but a new map was published after 2013.  A new map will be drawn if changes in the area call for it.



Results


A new map, the first since the launch of the power plant, is now available  with the latest information on structures, reservoirs and roads. The boundary of „untouched” wilderness has been updated to 5 km distance from roads, reservoirs and structures. The biggest change is due to the enlargement of Hálslón reservoir to the south, caused by the withdrawal of Brúarjökull glacier. Traffic has increased permanently on Brúarárleið route to the north from the west end of the Kárahnjúkar dam.

Monitoring Protocol



Metrics: What is measured?

Loss of wilderness (km2) according to the definition in Icelandic law for nature conservation. (Project effect: indirect).

Monitoring Protocol

New wilderness map was made in 2013.  New maps will be made as needed if changes in the area call for them.


Targets

Area of wilderness will not decrease after construction period (in 2007).


Possible countermeasures

Not applicable, monitoring only.

Changes of indicator

In forth phase of the initiative the numbers of the sustainability were changed. This indicator was originally number 31.1 and is referenced as 31.1 in early documents of the project.


Rationale for Indicator Selection


The landscape and visual impact of the Kárahnjúkar power project was an issue discussed in the Environmental Impact Assessment (EIA). This included the loss of wilderness in the highlands, an issue often cited in public discussion about the Kárahnjúkar dam.

Finding an appropriate definition for wilderness is not simple because human settlement has impacted most parts of the highlands in some way. Roads, bridges, and trails provide access to the highlands for motor vehicles and those vehicles influence wilderness areas so they can not be viewed as untouched. Several tourist huts and farmers searching for sheep also impact the land. Finally, one could argue that none of the highlands can be categorized as wilderness because of the changes in vegetation and soil erosion caused by overgrazing.

The Kárahnjúkar EIA used a definition of Wilderness developed by a working group of the Ministry for the Environment, but this working group was created after a decision in the parliament on May 12th, 1997, about the protection of wilderness areas. The working group definition found its way into new laws on nature conservation that were passed in 1999. Wilderness is defined as:

An area of land, at least 25 km2 or large enough so that solitude and nature can be enjoyed without disturbance from human structures or traffic from motor vehicles driving on land. The area should be at least 5 km away from human structures or other technical signs such as transmission lines, power plants, reservoirs and roads. There should be no direct human influence and nature should be allowed to develop without pressure from human activities.

Once the Kárahnjúkar power station will be operational, further loss of wilderness will mainly depend on changes in travel routes and tourism since no changes are foreseen on facilities related to the power plant.

Baseline



The map below shows the results from a workgroup of the Ministry for the environment about which areas close to Vatnajökull glacier should be defined as wilderness areas. The green areas represent wilderness areas. Travel routes and huts are located in the area north of the glacier and this decreases the area north of the glacier that is defined as wilderness. Obviously, some subjective estimation must take place to decide which travel routes can be accepted within wilderness areas and which can not. The route to Snæfellsskáli hut and to Sigurðarskáli hut in Kverkfjöll mountains are labeled as non-wilderness which leaves the mountain Snæfell and surrounding area outside the definition wilderness areas. According to this map, Vatnajökull glacier and surrounding wilderness areas are 14,500 km2.

The bottom picture shows loss of wilderness because of the Kárahnjúkar power station. Part of the loss is because of Hálslón Reservoir, around 460 km2, but the rest is because of the Jökulsárveita river diversion and facilities that will be built at Múli and Hraun, a total area of 275 km2. Total loss of wilderness because of the power plant is 735 km2.

Traffic on the Brúardalaleið route has increased during summers after construction work began and it became possible to drive a circle from Fljótsdalur and Jökuldalur valleys, over the highlands and across a bridge to Kárahnjúkar. This road improvement and increased traffic adds an extra 90 km2 to the total loss of wilderness in the area.
