Haubjerre Mire, Haubjerre or Houberskiarre is a mire, meaning a former relict lake, located west of the highest point on Ruhnu, Håubjärre (Haubjerre) Hill. The mire is covered by approximately 1 m thick Quaternary Period sediment layer (fen peat can also be found). During high water season, water also accumulates there. The area is covered by fen grassland.

The shallow hollows north and north-west of Haubjerre Hill are also former relict lakes (Keloskiarre, Djupkiarre). The second well-known boggy place in the area is Baskiarre west of Ruhnu Village. This former lake area is covered by an up to 1 m thick blackish-gray muddy layer of fine sand. In 1910, a ditch was dug in the process of developing agriculture and the lake was emptied out. Before that, the lake was connected by a stream that flowed through the village and into the sea at Pärsi.

Haubjerre mire is also represented in local folklore. People say that Haubjerre mire contains the remains of a Viking ship called Runö. When this place was still connected to the sea, the ship had supposedly gone there to look for shelter from a storm. The name of the ship is also supposedly the source for the Swedish name for the island, Runö.
