Abstract

The tolerance of disturbance of the ground and field layer vegetation in a moderately fertile Norway spruce (Picea abies (L.) H. Karst.) on Oxalis-Myrtillus type forest in Southern Finland was studied. One of the sites, a summer cottage yard had been raked regularly during the last 25 years. The structure of the vegetation was quite different compared to the other sample site situated in a virgin forest. The phytomass and percentual coverage of the vegetation was remarkable lower in the raked habitat. Tall mosses, Pleuroxium schreberi and Hylocomnium splendens had especially disappeared. Most grass shrubs had also deteriorated. Only Deschampsia flexuosa was quite tolerant to raking. The phytomass of the dwarf shrubs was lower in the raked area but their relative production was higher. Three different kinds strategies of species were described: species of virgin shaded forest, species of meadow-like forest floor and species which tolerate or benefit from disturbance. The raked habitat had a higher species diversity than the virgin area. Nitrogen and carbon contents were lower in the soil of the raked area.
