THE REHABILITATION PROGRAMME
14
REHABILITATION MANAGEMENT OBJECTIVES
15
Ob.2. Carry out restoration works where natural or semi natural character has been lost
16
"Ob.3"
  • Ob.3. Manage water circulation in order to improve the ecological conditions



  • Ob.4. Assess the effectiveness of existing buffer zones and if necessary recommend modifications
17
THE REHABILITATION PROGRAMME HAS TWO MAIN CATEGORIES OF PROJECTS
  • WETLAND RESTORATION PROJECTS
  • - Research, design, monitoring: DDNI in cooperation with RIZA – the Netherlands and Institute for Floodplain Ecology, Rastatt, WWF Germany
  • - Civil works: DDBRA
  • HYDROLOGICAL SYSTEM REHABILITATION PROJECTS
  • -Research and design: DDNI &RIZA
  • -Civil works: DDBRA


18
ADDITIONAL COMPONENTS
  • Restoration of habitats and ecosystems


  • Restoration of the endangered species


  • Restoration of the affected landscape
19
The main actors

WETLAND RESTORATION PROJECTS
  • Objectives:
  • Restore the specific functions of the wetlands
  • Restore lateral connectivity and reintegration in the natural river pulse system
  • Restore the natural habitats that support biodiversity and natural resources
  • Recover traditional economic activities of the local communities

BABINA-CERNOVCA PILOT PROJECT
  • S = 2,100 ha Babina, 1,580 ha Cernovca, former agriculture polders (drained areas)
  • Research: 1991-1994, cooperation with Institute for Floodplain Ecology, Rastatt, WWF Germany
  • Monitoring: 1995-2002
  • Project status: fully implemented, Babina reverted to wetland since 1994, Cernovca since 1996
  • Present status: a mosaic of water types, clear to turbid water systems, depending on the connectivity to the river

OTHER
WETLAND REHABILITATION PROJECTS
33

HOLBINA-DUNAVAT PROJECT
  • S = 5,630 ha, former fish farms
  • Research: 1993-1996
  • Result: Restoration strategy
  • Implementation status: investment funds available since 2003
  • Evolution:  water system reverted from turbid plankton-dominated to clear macrophytes –dominated state (!)

35
POPINA PROJECT


S = 3,600 ha, fish ponds
-Research: 1996-1999
-Implemented since 2000
-Status: permanent wetland connected to the river pulse system
36


FORTUNA PROJECT
-S = 2,115 ha
-Former polder for forestry
-Research: 2000-2002
-Present status: under implementation
37
Hydraulic connectivity restoration
  • S = 687 ha
  • -Origin: Islets formed by cutting meanders
  • -Research: 2002
  • -Restoration to be implemented


38
MEANDERS PROJECT
39

HYDROLOGICAL SYSTEM
 REHABILITATION
  • Objectives:
  • -close or calibrate the artificial North-South oriented canals
  • -calibrate the (semi-)natural West-East channels
  • -calibrate the lake entrances


  • From 3,400 km  of channels 329.5 km have been dragged, 8 canals closed and 5 sections calibrated

PILOT PROJECT OF ECOLOGICAL RESTORATION
CALARASI – RAUL ISLET S=3,875HA
45
Objectives
  • Restore and preserve the specific biodiversity of the Calarasi-Raul Islet
  • Benefits for population in the area by increasing of the employment and the development of traditional activities: fishing, reed harvesting, wood cutting and tourism
46
RESULTS
  • GENERAL STRATEGY FOR ECOLOGICAL      REHABILITATION OF CALARASI-RAUL ISLET
  • COMPLET PROJECT FOR REHABILITATION OF
  •      CALARASI-RAUL PILOT AREA
  • IMPLEMENTATION PLAN
  • INVESTMENTS COST-PLAN
  • BIOLOGICAL AND HYDROLOGICAL MONITORING
47
 
48
RESULTS
  • BASEMENT STUDY TO PROMOTE IEZER-CALARASI AREA AS NATURAL RESERVE
  • MANAGEMENT PLAN OF CONSERVATION
  • ECOLOGICAL REHABILITATION PROGRAM
  • STRATEGIES FOR PUBLIC AWARNESS AND RESEARCH
  • IMPLEMENTATION PLAN
