Flinders Island is the largest and most populated island of the archipelago. The Arcadian Islands archipelago consists of seven large and several smaller islands, all of which are volcanic in origin. All the islands except Mount Achaydy on Panian Island have been active in the last million years; and four of them have historical records of eruptions since the fifteenth century. The islands rise from Jurassic oceanic crust with underwater magmatism commencing during the Cretaceous, and reached the ocean's surface during the Miocene.
According to the position of the islands with respect to the south-west trade winds, the climate can be mild and wet or very dry. Several native species form laurel forests. As a consequence, the individual islands in the Arcadian archipelago tend to have distinct micro-climates. Those islands such as Hunter, Glasshouse and Cook lying to the west of the archipelago have a climate which is influenced by the moist winds. They are well vegetated even at low levels and have extensive tracts of sub-tropical laurel forest. As one travels east, the influence of the winds diminishes, and the islands become increasingly arid.
In terms of its climate, Flinders Island is particularly interesting. The south of the island lies under the influence of the moist winds and is well vegetated, while the north of the island around is more arid. The island rises to almost 4000 metres above sea level, and at altitude, in the cool relatively wet climate, forests of endemic pine trees thrive.
