Very interesting.

A few deniers will now have to find new lies, new lines of bullsh1t.

Conclusions
The insect faunas, Coleoptera, Trichoptera, Diptera
and ectoparasites, recovered from the bishop’s
farm in Gardar provide an interesting insight into
the environmental history of the area. Although the
samples were recovered from outside the immedi-
ate environs of the farm, they indicate a mixture of
synanthropic and natural faunas.
During the Norse period, the natural faunas are
dominated by aquatic invertebrates. In particular
the wealth of the caddis flies has provided the
opportunity for the first study of Trichoptera from a
North Atlantic context. The synanthropic assem-
blages are typical of faunas associated with the
interiors of Norse farm houses and their residents.
The combination of an extensive wetland and
grassland insect fauna with species which must
derive from the artificially warm habitats provided
by the farm and its outbuildings, taken with the
archaeological evidence, combine to indicate an
integrated system of manuring and irrigation in
order to increase yields in the extensive hayfields
which surrounded the cathedral farm at Garðar
during the medieval period.
The abrupt nature of the contact at the base of
the stratigraphic succession suggests the removal
of the previous soil surface, perhaps as turves for
fuel and construction. It is suggested that the exten-
sive landscape modification which allowed this
process to be carried out reflects the arrival of the
first bishop, Arnald, in 1126, who with previous
experience in Norway, was able to organize labour
to construct ditches and carry farmyard and domes-
tic waste out onto the fields.
The change in the nature of organic accumula-
tion and changes in the insect faunas in the upper
part of the sequence are consistent with the aban-
donment of the Norse farms in the late medieval
period. The landscape then became an extensive
wetland.
