Biodiversity continues to increase in result of recovery project of the Rio Tinto river section on the Lipor Ecological Trail
The Rio Tinto intervention assumes a preponderant role in LIPOR strategy for Biodiversity and Social Responsibility.
The river Rio Tinto is a small tributary of the river Douro, about 12 km long, but with a high importance in the region, covering the municipalities of Valongo, Gondomar, Maia and Porto.
Although at LIPOR the expression of the Rio Tinto is reduced, the Organization considers that its involvement in its protection must be complete.
The Tinto River Valuation project intends to contribute to the definition of a joint action among several entities, whose premises are to identify and register areas of contamination, monitor the evolution of water quality, allowing to sustain from a technical-scientific point of view, the indispensable interventions for the recovery of the river, revitalising the riverside ecosystem and to define future sustainable uses.
In this context, in addition to several interventions in the river bed and river banks, using natural engineering techniques along the stretch that passes through Lipor and that can already be enjoyed in the Ecological Trail, Lipor has recreated the figure of the "Guarda-Rios" (river keeper).
With daily monitoring functions for the stretch of the river Rio Tinto that borders LIPOR's facilities, our "Guarda-Rios" fills out a dailly Inspection Bulletin, which is compiled and sent to the Rio Tinto Collaboration Protocol Partners.
In 2018 the work of the "Guarda-Rios” was very fruitful, with 227 visits to the river, corresponding to 975 inspections and 2925 parameters inspected. It should be noted that over the course of the year, we increased the inspection points from two to five.
In terms of results, despite a slight improvement in the quality of the river and water, 300 occurrences were detected in 47 days of the year. Regarding the types of occurrence (odour, colour and residues), the results were distributed as follows: 26% of occurrences related to odour, 36% of occurrences related to colour and 38% of occurrences related to the presence of solids and foams.
Nevertheless, all the work that has been done has produced very positive results, and the Rio Tinto's biodiversity continues to increase!
This year ducks, newts and salamanders have been observed, a sign that the quality of the ecosystem is improving.
This project has, as partners of LIPOR, the Municipalities of Valongo, Gondomar, Maia, Porto, Gondomar, Porto and Valongo Water Systems, Fernando Pessoa University, the Portuguese Environment Agency, I.P./ North Hydrographic Region Administration and the Town Councils of Rio Tinto, Ermesinde, Águas Santas, Baguim do Monte and Campanhã.
