Onsö nature reserve
Mariestad

In the middle of the island there's mixed forest of farmer type, and in south grows deciduos forest, among other things oak and hazel. The nature is deeply varied. Most important among these are the old coniferous forests dominating the island. Here's an old generation of trees consisting of block-branched firs, thick-branched pines, gnarly oaks, as well as more-or-less mushroom-filled aspens, birch and alder. Many kinds of dead wood in many different stages of discomposition are present. During spring, there's plenty of hepatica flowers, as well as more demanding species such as spring pea and muskroot. The later forest types adds to a rich grove flora on the island.

The islets and islands north and west of the island are relatively bare. Colonies of varying size of great black-backed gull, black-headed gull, arctic tern, and common tern breed at some of them. Onsö is relatively hilly and a beloved place to visit. Especially during the summer half of the year, Onsö is a valuable spot for boating visitors, with beautiful natural harbours and places for bathing and relaxing.
