and autonomous community with Santander as its capital city.
Numerous authors, including Isidore of Seville, Julio Caro Baroja, Aureliano Fernández Guerra and Adolf Schulten, have explored the etymology of the name Cantabria, yet its origins remain uncertain.It is claimed The name Cantabria could also be related to the celtic root "kant" or "cant" meaning edge or rim thus "coastal district," or "corner-land", "land on the edge" thus having the same probable derivation as name of the English county of Kent.This causes a decrease in air humidity and rainfall.These conditions are more frequent in autumn and winter, and the temperatures are commonly higher than 20 °C (68 °F).The great limestone masses of Picos de Europa also stand out in the southwest of the region: most of their summits exceed 2,500 m, and their topography is shaped by the former presence of glaciers.
Due to the gulf stream, Cantabria, as well as the rest of "Green Spain", has a much more temperate climate than might be expected for its latitude, which is comparable to that of Oregon.
The rapidness of their waters, caused by their steep descents, gives them great erosive power, creating the narrow V-shaped valleys characteristic of Green Spain.
The environmental condition of the rivers is generally good, although increasing human activity due to rising population in the valleys continues to pose a challenge.
This provoked a surge of eucalyptus - see Eucalyptus article on Spanish Wikipedia - plantations (and to a less extent of Pines) which often hid the illegal destruction of native forests, just as the spread of livestock farming had done in the past by the endemic conversion of forest into prairie.
This acts have been laxly controlled by the local councils or the central governments, in a process that clearly follows the saying: "Pan para hoy, hambre para mañana" (which translates as: "short-term gain, long-term pain").
These grasslands are mingled with plantations of eucalyptus and native oak.
