Liming of forested catchments can represent a valuable alternative to counteract acidification of
terrestrial ecosystems and to promote the recovery of biodiversity that has been impoverished
by acidification. However, the validation of such a strategy needs to adopt a global approach
integrating hydrobiogeochemical researches as well as studies on the dynamic of biodiversity
and related ecological processes. The present study was conducted in equipped experimental
sites located in the Vosges Mountains (NE France) including two forested catchments that have
been limed in fall 2003. The project aims to evaluate in a global perspective whether the recovery
towards pristine abiotic characteristics induces a recovery of soil macroinvertebrate biodiversity.
The study has been carried out on 4 catchments, eg. two acids (sandstone and granit), and two
limed catchments. For each catchment, three areas were selected and 7 soil cores, distributed
every 5 m along a transect, were sampled for classical soil analysis (pH, organic matter content,
granulometry?). Soil macro-organisms were sampled by soil hand sorting on the same transect.
Individuals collected were immediately fixed in 70% alcohol for further identification. Results
showed that liming induced a significant increase of pH value, from 3.88 to 4.26 on sandtone
(ANOVA, p<0.00001) and from 3.91 to 4.15 on granit (ANOVA, p=0,000638). Significant
differences in soil macroinvertebrate abundances were also observed, and limed sites showed
a significant decrease of the total abundance of soil fauna in comparison to acid sites. This
result is mainly explained by the decrease of insects and particularly coleoptera (adults and
larvae), diptera larvae, and arachnids (Mann-Whithney, p<0.005). Contrastingly, earthworms
were favoured by liming and pH increase, and their abundances were signicantly higher in limed
sites (Mann-Whithney, p<0.005). Positive effects on earthworms were also found by Deleporte
and Tillier (1998) and recently confirmed by Potthoff et al. (2007). Similarly, negative effects on
arachnids have been also reported by Ormerod and Rundle (1998) studies. More surprisingly,
we found negative effects of liming on carabidae, and, more generally, on coleopteran. These
results contrast markedly with previous findings reporting enhanced density of coleopteran in
limed sites (Theenhaus, 1995). In conclusion, four years after liming, contrasted effects were
observed. Other investigations are now conducted in order to better understand interactions
between biotic and abiotic factors, and their possible consequences on soil processes (such
as organic matter decomposition). MenosLiming of forested catchments can represent a valuable alternative to counteract acidification of
