Default Biologists Call For Network Of Protected Rivers

Biologists Call For Network Of Protected Rivers
ScienceDaily (May 22, 2009) An international research team has used the Guadiana River basin, in which 92% of the species are under threat, as a reference point to measure the loss of aquatic biodiversity and its conservation value. A new study reveals that the state of fragmentation of Iberian river basins is "seriously endangering" the freshwater fish that inhabit them, and highlights the need to create new protected aquatic reserves.

Biologists Call For Network Of Protected Rivers
excerpt from above:
Quote:
The study, which has been published in the latest issue of Hydrobiologia, is based on the premise that there are few nature reserves for the conservation of aquatic biodiversity. "Rivers have been treated as being of secondary importance, unless they represent an opportunity to conserve the land environment", Hermoso adds.

To date, the criteria used to select protected areas have had "nothing to do with conservation", the scientist points out. Factors such as scenic value, lack of development, inaccessibility and low potential for commercial use are applied to select areas, resulting in "conservation strategies focused on areas that are the easiest to protect and with the least need for short-term protection."
