Problems
Water quality:
Phase I. = algic lake
Rhapsodic nutrient circulation
Vegetation changing, lack of macrophytes.
Lack of water facilities (for example fish ladders)
Decay of the reedbed in the Ingó-grave:
- Too high water-level
- Flow conditions
- Lack of opportunities for flexible operation
- Lack of the spawning areas
- Lack of natural zonation

What can we do…?
Possible sources of conflict: contradiction between
perceived and real professional interests
for example. inland water, vegetation in the creek
bed, hunting activity.
Historical map by Ignác Müller, 1769
Habitat – restoration
rehabilitation
modification…
Conservation requirements for utilization of
wetlands
Ensure the survival of the species to be protected
Do not hauled into alien species
Do not be harmful to the environment
Adhere to the ethical standards
Interventions aimed at protecting native fish species
in protected areas
Water movement for the vegetation growth
Fish ladders
establish temporary water covered areas
invasive, non-native species displacement

Creating opportunities for flexible operation
Continuous control during implementation
and after…
Target or source of danger? Circular dam ripping
New wetlands
Temporary water covered areas.
Same aims?
Creation of temporal water body
Complex wetland
Ingó water level decreasing.
Unexpected situations,
operational solutions.
