Take the children on an exciting discovery tour in the forest, or seek out the old hay fields along the forest edge. Rambjøra offers a large diversity inside a little area: black alder swamps, old oak trees and flower meadows.
Surrounded by lush swamp vegetation, one finds Myravatnet. Here, there are good growth conditions for plants, and several large swamp plants are common around the whole lake. A bit out in the water, beaked sedge and water horsetail create a more or less clear zone. Bog bean, with its beautiful white flowers, appears already in May. Eared willow also flowers then, a three-metre high bush that is most common on the eastern side of the water. American water plantain, giant bur reed and elongated sedge are somewhat rare swamp plants in Norway, but they grow both in Myravatnet and in other lakes in Fana. The lake otherwise has a varied supply of northern pike, leeches and the endangered crustacean waterlouse, that is found in only a few places in all of western Norway.
On the slope above the lake there is a dense deciduous forest, extending all the way up to the steep rocky ledge. Elm, ash and hazel are characteristic tree types, but also sycamore maple is found in reasonable amounts. As in many other areas around Bergen and in the county generally, sycamore maple has spread to the forest from trees planted on private properties, and it is becoming steadily more common. This introduced tree species thrives so well that it may outcompete the native tree types.
Black alder is perhaps the most usual tree species in Rambjøra. It tolerates much moisture and grows on the edge of Lake Myravatnet and over large areas of the hill in the eastern part of the preserved area. Black alder has become more common after the activities of hay-making and grazing have decreased. An arial photo from the 1950s shows that the area at that time had only a few scattered trees. That some of the hayfields on the south side toward Tveiterås are once again cut, gives hope that some of the beautiful flowering meadows might survive.
