Ubiquitous midges are almost completely absent in Myvatn, called “Lake Midge” this year. However, while many may celebrate the lack of thick clouds in gnats that generally characterize the region, RÚV has a long-term impact on local birds due to the depopulation that occurs in a 6-9 year cycle. Report to give.
Arni Inalson, director of the Myvatn Institute, says there are as many as 100,000 freshly hatched turtles around Myvatn during normal season. However, this year there are just under 1,000 people.
Midge is an essential food source for birds around the lake, but it is rare today, Arni reports. As a direct result, he explained, “I can’t find any chicks in the lake.” “There are 20,000 pairs of ducks, but few are raising young children. They mainly ignored the nest and stopped laying eggs. They threw their eggs and left them in the nest. Therefore, the hatching chick only lives for a few days. “
Arni estimates that the Midge population has declined 10,000 times this year. The dramatic decline in Midge can be attributed to the fluctuations in Myvatn, where Midge devours all food sources at the bottom of the lake. “There is no food on the bottom of the lake, the population of small insects is reduced, fish are coming in and finishing everything that remains. […] And there is no midge left. “
According to Arni, this happens every 7-9 years. This is about eight years after the Midge population last collapsed. As a result, bird populations will be much lower over the next few years. “This creates a dent in the inventory,” he concludes. “It does not update itself.”
