Aerial photography offers an effective overview of reindeer distribution. The monitoring is carried out by the Engineering Institute of the University of Iceland, on an annual basis, in an area covering 400 km2.
2.3 million Birch trees and approx. 50,000 Mountain ash trees have been planted within 1200 ha of land in the Hekla area. The objective of the project is to reclaim one of the key ecosystems in Iceland: the birch tree ecosystem.
