Project summary

Edit project overview to modify the project summary.

The main objective of the project is to promote and support the environmental recovery of the Segura River Basin by improving and strengthening the connectivity between natural ecosystems, promoting the conservation of the area and improving its public use by:

1. Increasing the river ecosystems continuity and permeability in order to restore its natural dynamics and the mobility of the species along the Segura and Moratalla rivers

2. Combating ecosystem degradation and fragmentation to restore their role as ecological corridors

3. Improving the ecological status along both rivers

4. Increasing biodiversity of fluvial and riparian ecosystems

5. Promoting social awareness

6. Disseminating knowledge and transferring the results to the Segura River Basin Management Plan and to other areas with similar environmental problems

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

In order to validate these actions and evaluate the results, the project carried out a comprehensive monitoring program including biological, physical-chemical and hydromorphological indicators. This facilitated the subsequent transfer to the rest of the basin and other rivers with similar problems.

Monitoting actions were focused on :

+ Operation indicators at fish passage systems

+ Fish community and populations

+ Bird community and riverbanks associated fauna

+ Spatio-temporal dynamics of vegetation communities in the restored areas

+ Ecological status of water bodies and sediment monitoring in each weir

Lessons learnt

Edit project overview to modify the lessons learnt.

Upon completion of the project, the following results have been listed:

+ More than 10,000 fish are using the fish passages. 80% of fishes which try to use the vertical-slot fishway achieves it, 50% does it in less than half an hour.

+ First weir removal within the Segura Basin

+ Volunteer collaboration and the landstewardship scheme are essential for the achievement of a favorable development of the riparian vegetation. In case of volunteers, thanks to its implication in plantation and refered to landowners for their commitment to properly mantain riversides and to avoid the development of alien species spots as in the case of Arundo Donax.

+ Results obtained by the removal of Arundo Donax have been diverse, depending on the area and the technique applied.

+ Plantation has been more effective for willows (Salix sp), poplars (Populus sp.), elms (Ulmus minor), mastic trees (Pistacia lentiscus) and rosebay (Nerium oleander).

+ A proper implementation of the plantations, a good size of the holes, the location of each plant and the time of plantig are essential for the succes of the works.

+ One of the most succesful achievements has been giving visibility to the problem and to the project and the social awareness about it.
