The Südtannenmoor is a nature reserve 2 km south of Klein Berßen ( Emsland district ) . The ordinance issued on June 25, 1959 has since been deleted and replaced by a new one on December 31, 2009.

The core of the approximately 4.9 hectare protected area was originally formed by two heather ponds , only separated from each other by a low sand ridge . They are framed on all sides by pine and spruce forests.

The smaller, approximately 50 × 95 m large pond has now fallen completely dry and is largely overgrown with moor birches ( Betula pubescens ), pines ( Pinus sylvestris ) and willow bushes. In the herbaceous layer is dominated today Tonquil ( Juncus effusus ) and moor grass ( Molinia caeruelea ). In the past, numerous rare plant species grew here (according to Altehage 1955), including:

The northern pond still had a larger water surface in 2008, which was covered by the leaves of the white water lily ( Nymphaea alba ). At the edge of the water there are large stocks of the common sedge ( Carex rostrata ) interspersed with herds of the fever clover ( Menyanthes trifoliata ). The swamp blood-eye ( Potentilla palustris ) is also found here and there . All of these species tend to indicate a medium nutrient content in the water. The narrow-leaved cottongrass ( Eriophorum angustifolium ) with its cotton-like fruit clusters gives the pond a peculiar charm in early summer.

The edges of the large pond recorded earlier by a high moor-like vegetation, which from the Middle peat moss ( sphagnum magellanicum was coined). Find or were located here:

Parts of the bog have now dried up due to the general lowering of the groundwater. Instead of the original vegetation, the pipe grass is expanding.

The southern fir moor owes its special importance to the previously very numerous occurrences of the flower or bladder rush ( Scheuchzeria palustris ), which are now threatened with extinction in all of northwestern Germany . In 1957, hundreds, if not thousands, of the species are said to have existed. In 1976 only 25 flowering and several dozen non-flowering rushes were found (Runge 1982). Since then, the species seems to have spread again. A renewed examination of the site in 2011 revealed over 1000 specimens.

In early summer the pond is filled with the concert of green frogs . Numerous dragonflies dance over the water surface .
