Researchers at the School of Agricultural Engineers of the Polytechnic University of Cartagena (UPCT) have demonstrated the suitability of soils contaminated by mining revegetate with tree species such as pine and cypress endemic Cartagena.
"We have seen the importance of a type of plants, which we have called pioneer or colonizing cousin, who play an essential role in improving the conditions of soil fertility and that eventually lead to the establishment of other species of greatest relevance ecological, "explains Isabel Parraga, author of the research.
His doctoral thesis, entitled 'The importance of ecological and soil gradients in the distribution of vegetation pioneer in old mining dams in the Sierra Minera of Cartagena-La Union', was led by researchers Hector Miguel González Conesa and Nazareth.
"The study reinforces the importance of interactions between plant species to achieve a sustainable vegetative cover on land degraded by mining activities," says Conesa.
The work, developed at the School of Agricultural Engineering UPCT, has revealed the feasibility of using tree species in the restoration of mining waste.
"Until now, most research in this field had focused on low plants," said Nazareth González, a researcher at the VU University of Amsterdam.
"But the use of tree species had not yet been studied in depth. The trees provide greater protection of soil against erosion and improve the aesthetics of the landscape," he adds.
The thesis includes novel mode of employment cypress Cartagena.
"We have two objectives: firstly facilitate soil conservation and on the other, collaborate in the preservation of this endemic species," notes Isabel Parraga.
The scientific interest of the thesis has been endorsed by the publication of seven scientific papers in international journals of high impact in the environmental area, which, in the words of Parraga, "can help implement the results of our study in other semi-arid areas with environmental issues like ".
The completion of the doctoral thesis has been possible thanks to funding from the Seneca Foundation of the Autonomous Community of Murcia and the Ministry of Economy and Competitiveness.
