Conclusions:

- Larval stages mainly appear in temporary ponds. Permanent ones are crowded of crawfish and fish that prey over them.
- Temporariness of ponds determine which species can use them to complete their cycle.
- The irregular management of poplar groves impede the stabilization of some species populations.
- Although today habitats could be disadvantageous, there is the potential to accommodate a greater number of individuals.
- In the absence of water analysis final results, we believe that the quality of water may be another factor influencing the reproduction of amphibians.
- Pioneer species found in the spaces generated by the extractive activity suitable habitat for reproduction.

Lines of action:

- Improvement of existing habitats and creation of new ponds to turn the lagoons area into a source of amphibians.
- Creation of new ponds in the holm oak grove to improve connectivity with amphibian populations found in the south, outside the limits of exploitation.
- Creation of ponds in the service area of the abandoned railway and adaptation of the steps through potential barriers to facilitate connection with amphibian populations found in the west and in the south.
- Proposal of a management plan for the effective reconciliation of extractive activity and conservation of pioneer species.
