Leirvågen
A marsh is a grassy meadow that is strongly influenced by salt from the sea. This type of nature is abundant in Denmark, among other places. The flatlands along the river that run out by Leirvågen, are the municipalities' largest marsh. At spring tide, these flatlands are flooded underwater for several hundred metres in over land.
Herlandsnesjane
Herlandsnesjane, a four-kilometre long peninsula in Lake Storavatnet in the middle of Osterøy, is well known among botanists. Here lies an unusually large and diverse bog.
Lonelva
It is said that the salmon populations with the largest and the smallest salmon in the world both come from the waters that run out into the fjord system around Osterøy. Vosso is supposed to have the largest spawning salmon to be found in any river, whereas Lonelva is said to have the smallest.
Purkebolsvatnet
Lake Purkebolsvatnet is perhaps western Norway's largest sleeping city - for birds. They come in the thousands, usually in later summer and autumn. The barn swallows alone number 10 000 - 12 000 at their most numerous.
