In the area
of Lake Cerknica we are conducting detailed botanical zoning
of habitat types. In this way we will obtain expert bases
for all further campaigns, define threats to habitat types
and carry out the activities necessary for conservation of

encompasses many endangered habitats protected by the Directive
on the Conservation of Natural Habitats and of Wild Fauna
and Flora of Natura. The largest habitat protected under
the Habitats Directive is the intermittent Lake Cerknica.
Within this habitat there are many smaller ones, for instance:
Molinia meadows on calcareous, peaty or clayey-silt-laden
soils, Central European mesotrophic to eutrophic lowland
hay meadows with the healing Salad Burnet Sanguisorba officianlis
and Field Meadow Foxtail Alopecurus pratense, transition
mires and quaking bogs Dujce and Benetek, hard oligo-meso
trophic waters with bentic vegetation of Chara ssp. and natural
eutrophic lakes. The last two can be found in areas where
water remains the longest. In order to efficiently conserve
and protect such habitats we need to know where they are
located and how they should be treated. Botanical zoning
with the inventory of common plant species is carried out
specifically for this purpose. A comprehensive overview of
plant communities will provide the basis for preparing the
management and renaturation plan for the stream sections
Tresenec and Goriški Brežiček. Habitat type zoning is a preliminary
action important for comprehensive protection of Lake Cerknica.

In the scope of the project the Biotechnical Faculty is responsible
for habitat mapping of the Lake Cerknica area and for preparing
expert grounds for the management plan.
