Abstract

We studied the response of the macrofauna to forest conversion from pure coniferous stands into semi-natural montane forests in the southern Black Forest (Germany). The investigation was carried out by comparing existing stands that represent the four major stages of the envisaged conversion process. Major results are: (i) environmental parameters indicate a significant alteration of the soil environment, (ii) neither an overall change nor a clear trend in macrofaunal richness and abundance could be established, and (iii) the data for the different taxa suggest specific responses to the conditions of the individual conversion stages. In general, saprophagous taxa seem to be mainly driven by alterations of the resource base (litter quality, microbial parameters) while predatory taxa tend to respond to changes at the consumer level. Associated alterations in the functional structure occurred for macroengineers (earthworms), primary consumers (diplopods, isopods) as well as a wide range o
