Tuomilehto is a herb-rich forest extending over four hectares, and as the name suggests, bird cherry (tuomi in Finnish) forms a thick shrub layer which also contains buckthorn, rowan and fly honeysuckle. The vegetation in the forest includes many plant species which are typical for herb-rich forests, such as baneberry, redcurrant, guelder rose, finger sedge and wall lettuce. From the depths of the forest, one can hear the sound of the star singer of the herb-rich forest, the garden warbler, and the memorable, quickening song cycle of the wood warbler.
