3 Location and specific of the area 3

4 Location and specific of the area Danube Delta Biosphere Reserve Europe s largest protected area (5,800 km 2 ) mosaic of 30 different ecosystem types 9 vegetation units (20 classes) 158 plant communities 4

5 Need for monitoring Conservation of the habitats within Natura 2000 and WFD Identification of changes in the distribution and structure of the habitats Hydro- morphological changes: e.g. costal zone erosion or deposition, sand dune formation and movement; Hydrology: e.g. flooded or not, period of food; Salt dynamic water characteristics (transparency, aq. plant cover, algae blooming). 6

6 Need for monitoring Economical purposes Assessment of the harvesting potential of the Danube Delta natural resources (reed, forest, grassland, medicinal plants, honey flora) monitor land management : e.g. unharvest, harvested in winter, harvest in summer for hay production, overgrazed; Monitor the Status : e.g. burned, insect damage, snow damage, etc. specify bearing capacity of the soil (for mechanical harvest) 7

19 Test results of FAO s LCCS 2 LCCOwnDescr Aquatic vegetation Closed Medium To Tall Rooted Forbs On Permanently Flooded Land (Persistent) LCCCode L11M212O5P5R1Zt11 LCCLevel LCCLabel / Attribute A5A12B4C1XXXXF1-A8B15C4-L11M212O5P5R1Zt11 Major Landclass: Level Land Plain Lithology: Unconsolid. Clastic Sedimentary Rock - Silt Climate: Temperate Continental Altitude: < 50 m Water Quality: Fresh Water The main layer consists of closed forbs on seasonally flooded land. The crown cover is more than (70-60)%. The height is in the range of m but may be further defined into a smaller range. The vegetation consists of one single layer. 22

20 Conclusions I Results of exercise: EAGLE concept helps make s wetland LU/LC classes INSPIRE-compliant (INSPIRE Pure Land Cover Components & HILUCS classes); Management and status aspects can be easily described with matrix tool; Proposal: Notification of the bearing capacity of the soils may be part of Bio- Physical Characteristics; Remote sensing detectable classes such as water turbidity (algae blooming or SS) and presence of floating and submerge aquatic vegetation may be included in the matrix. 23

21 Conclusions II FAO s LCCS has also the possibility to describe well (Bio-) Physical Characteristics and better water quality characteristics while EAGLE permits a more consistent separation between LC and LU information and the Characteristics are flexible and can be adapted to particular user needs, for example information of the status of the reed beds (e.g. burned or insect damaged). 24
