SOPHIA PERDIKARIS, GEORGE HAMBRECHT AND RAMONA HARRISON effective deforesting agents worldwide and provide an excellent way to convert initially over-abundant wood land into human food) had done their job by the later 12th century. Forests had shrunk, or to put it another way, pastures had increased to the point where their services were no longer needed. Palynological data collected by Ian Lawson and Katy Roucoux (Leeds) and work on widespread charcoal pits by Mike Church (Durham) suggest a complex pattem of deforestation and multiple woodland use for the region that also appears to reflect a long term nuanced management strategy not easily reconciled with the early view of ecocidal Viking Age settlers (Church et al. 2007, Lawson et al. 2009). Mývatn is today world famous for its huge migratory waterfowl population migrating from both Eurasia and North America. Documentary records extending to the mid-19th century indicate this natural resource has been sustainably managed to produce tens of thousands of eggs annually for human consumption without endangering the waterfowl population. Farmers carefully collected only a few eggs per nest and did not normally kill adult birds. Excavations in Mývatnssveit have repeatedly uncovered sheets of bird egg shell in midden contexts datable from first settlement down to the 18th century, and SEM analysis has revealed that most are indeed duck eggs. At the same time, there are few bird bones in fhe archaeofauna, and these are nearly all ptarmigan (grouse) not waterfowl. It would appear that sustainable management on the community level has been effective in Mývatn for over 1200 years. Marine Resource Networks and the Origins of the Codfish Trade The same archaeological sites from the Mývatn region have revealed a surprising amount of specimens of marine species, given their location 50-70 km from the sea. While seal bones, porpoise, eggs of marine bird species, and marine mussel shells (that were most likely transported attached to seaweed) have been found at sites in the Mývatn region, the most com- mon marine resources found are cod- family (Gadidae) fish. Local trout and charr (Salmonids) from Lake Mývatn and the surrounding rivers make up the majority of identified físh specimens at all the sites, but surprisingly the marine fish bones regularly make up 15-20% of the físh remains from these deep inland sites datable to the 9th to 19th centuries. Analysis of the skeletal element distribu- tion reveals that the marine fish in earliest times soon after the 871 Landnám tephra fall entered Mývatnssveit as headless flat or round dried prepared fish similar to the better known stockfish traded worldwide by late medieval times. This Viking Age distribution of marine resources in inland sites in Iceland is best dated in the Mývatn region but there are other inland sites outside of the Mývatn region in Iceland where marine resources have been recovered (McGovem et al 2006). Despite a well developed Viking Age farming economy and locally available freshwater fish and wild birds inland farmers in Iceland felt the need to provi- sion their households with dried fish products and these were indeed widely available. This at a time when research has demonstrated that marine fish prod- 46
