The Farnachmoos has been a designated nature reserve since 1976 in the area of ​​the municipalities of Alberschwende and Bildstein in the Bregenz district of the Austrian state of Vorarlberg .

location

About one and a half kilometers northwest of Alberschwende and two kilometers east of Bildstein, the Farnachmoos with its grass lawn , wet meadows and an upland moor extends over a south-west-north-east oriented ridge . Peat cuttings , dry moorland and trees with buckthorn , common spruce and downy birch characterize the area at an altitude of 860 to 880  m above sea level. A.

geology

The Farnacher Moos lies in the area of ​​the transition from the erect (granitic) molasses to the pressed, folded molasses. It is partly carbonate, partly marly and clayey, partly silicate dominated sedimentary rocks . Above this lies late Ice Age moraine material . In such environments, accumulating moisture is often decisive for soil formation, here for the formation of a raised bog.

In the uppermost profile area up to a depth of about ten centimeters there is weakly decomposed moss peat. Below that follows peat in the various profiles with varying degrees of decomposition from dark brown to almost black. In places the Torfdecke reaches deep over a meter, while in other places starting at around 65 cm under overlapping light gray-green clay / tone starts. In the peat profile, too, there are more or less clear debris in places. The peat cuttings show regeneration that has progressed to different degrees, in some of which reed herds have settled. The northernmost part of the ridge has not been changed by peat extraction, but attempts have been made to drain it through a ditch.

Soil profile

The pH value of the site is in the strongly to extremely acidic range over the entire profile (pH value 3 to 4). The carbon content shows the high content of peat down to the lowest depth. The lowest level in the mixed sample from the three profiles is strongly characterized by the high proportion of clay / loam. The trace elements aluminum (Al), chromium (Cr), iron (Fe), cobalt (Co), nickel (Ni) and vanadium (V) show a similar behavior . They thus indicate their substrate- bound geogenic origin. Lead (Pb) and cadmium (Cd), to a lesser extent copper (Cu), molybdenum (Mo) and zinc (Zk) indicate a strong influence of immission . Phosphate (P) and potash (Ka) content indicate the nutrient proportions currently available to plants and are divided into supply classes (very low, low, sufficient, high, very high) according to the Austrian fertilizer guidelines. This classification basically applies to intensive agriculture and has to be put into perspective in the area of ​​extensive wetland areas.
