The management of ecosystems and natural resources implies in certain cases the need to act to correct damage, reverse a trend or protect a species, site or ecosystem. Both human activities that directly transform the natural environment (hydraulic works and exploitation of water, mineral or living resources) and those that affect ecosystems in a more delayed manner (climate change, introduction of invasive species, etc.) may require corrective, palliative or compensatory measures. Since in all cases dynamic processes are affected, these measures must be adaptive and efficient.

ECOHYDROS prioritises knowledge of key elements as the basis for ecosystem management, using this knowledge and access to new technologies to act in an efficient and minimally invasive manner. Solutions are offered that intervene on certain organisms by means of electrical techniques for the capture, guidance and rescue of fish or the fight against harmful algae and invasive micro-organisms by means of ultrasound. In application of the concept of biomanipulation, techniques for the control/removal of species, and others that favour the implantation of certain groups of organisms to restore food webs or functionalities (controlled wetlands, floating islands, bioremediators, etc.) are virtually tested and applied.
