·Area:40.178 Km² ·Population:3,72 millions ·Population density:92,63 person/Km² ·The most important rivers are “Miño”. “Eo” and “Sil” ·The most part of the population lives near the coast, specially in three big cities.
Characteristics:
seasons
variations on the coast than interior
Soils are generally:
which gives the upper layer its typical dark color
plants
We can distinguish three types of landscapes:
Some endemic
Areas with special ecological characteristics restricted for different economic and productive uses. Around 15% of territory
·Soil salinization ·Erosion of surface ·Fires ·Contamination of the soil and water ·Destruction of river banks ·Compactation of the soil
It is not the main problem in the region, but it appears in areas where rainfall is less abundant and fertilization is excessive It affects: · Chemical properties
· Microorganisms ·Plant growth
Caused: · Loss of vegetation cover Excessive cattle · Fires · Torrential rains
Contamination of the soil and water
There is a very large thermal power plant in Galicia
It causes: ·Biodiversity loss · Change river properties ·Erosion · Water contamination ·Floods
In general, soil compaction is caused by intensification of the soil, both by abiotic and biotic factors
In these two regions, monocultures of eucalyptus and pine are very common (they are not native), causing: · Fires ·Pests · Land intensification · Destruction of ground cover
In these regions, especially dairy farming is very intesive, leading to environmental problems that affect the surrounding areas
¡Native plantations!
