Partners/contacts sought for German Cratoneurion springs project
the more unusual priority habitat types listed in Directive
92/43/EEC* are petrifying springs with tufa formation (Cratoneurion).
These habitats consist of springs where water comes out of
the ground with high calcium carbonate content.
specific mosses and algae (with the genus Cratoneurion
as leading type) extract carbon dioxide from this water,
the calcium forms mineral deposits (tufa) on the plants,
coating them to create bizarre shapes.
The German LIFE-Nature project for the protection of springs
with tufa formation in the Franconian Alb (Bavaria), has
reached a critical 'conversion phase'. With regular updates
in its newsletter, the project beneficiary "Landesbund
für Vogelschutz in Bayern e.V." would like to
inform interested parties of its progress; while at the
same time would like to initiate a technical exchange
of information with other partners.
The project is entitled: "Measures of optimisation
of petrifying springs with tufa formation (Cratoneurion)
and their surroundings in the Franconian Alb" (LIFE03
NAT/D/000002). Launched in July 2003 (with closure scheduled
for December 2007) its main aim is the restoration of
these springs by carrying out technical actions to reverse
past interventions which have included encasing them in
constructions to make them more "attractive"
or (at the other extreme) trying to drain them or using
them as rubbish tips.
To combat the insufficient buffering of the spring habitats,
appropriate farming and forestry practices are being promoted.
The target is to repair at least 54 springs. As one of
the first-ever projects dedicated to this specific habitat
type, the project also hopes to fill a knowledge gap concerning
the restoration and enhancement methods for Cratoneurion
springs, to develop transferable techniques and to give
scientific references for specific actions.
