For the most part, the history of forestry in Spain was one of increasing deforestation. [1] Wood (Spanish: madera) long was the main source of energy. [1] In the 20th century, efforts were taken to reverse the trend, increasing the forested area in the country from then on. [2] [n. 1]
Los quejigares can often include maples, serbales, European serviceberry or snowy mespilus (Amelanchier ovalis), common privet (Ligustrum vulgare L.) and common dogwood (Cornus sanguinea); their degradation can lead to extensive thickets of box.

Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia , Brazil , Canada , the United States , China , Australia , the Democratic Republic of the Congo , Indonesia , India , and Peru .
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
There are many causes of transition, foremost, economic development leads to industrialisation and urbanisation, pulling the labour force away from the countryside to cities. For example, in Puerto Rico, industrial policies which subsidised manufacturing led to a transition towards urban sector manufacturing and service jobs, leading to land ...
Dehesa in Extremadura, Spain.

Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use.
It includes the mountain forests of southern and central Spain. The ecoregion has montane Mediterranean climate. Rainfall averages 1,100 mm annually, and can exceed 1,500 mm in some high-elevation areas. Below-freezing temperatures and snow are common in the winter months. [2]
