Rare sandy beaches
Järflotta is predominantly covered by pine trees, with cultivated fields in the middle of the island around Järflotta gård. Pine and spruce are found in some mixed forests. There are also large sandy areas on the island that were formed when retreating ice sheets stood temporarily still, between 8900 and 8300 BC.
Nature reserve from 1968
Järflotta is privately owned, but the landowner converted the island into a nature reserve in 1968. This means that the island will not be exploited, and that the owner receives financial compensation from the Swedish Government and Stockholm County Council. The Archipelago Foundation protects and manages the natural environment. The beautiful rocky islands of Viksten and Gunnarstenarna, also included in the nature reserve, are important habitats for birds.
