Data

The first figure shows the deforestation of Maipo River (30 degrees South latitude, 70 degrees West longitude) from 1989 to 2009. This area, right south of Santiago, roughly represent the central region of Chile. The dark black regions below represent the forest in Chile. The white areas show where most of the agriculture was practiced. The light gray areas represent the population of this region. The darker shade of gray serves as the urban life during this time period. The trend shows that over last twenty years, area of forest has decreased significantly to make room for more agriculture and population. 

The second figure magnifies the northwest part of the area during the years of 1989, 1999, and 2009 to show evidence of the deforestation that occurred. As one can see, the amount of forest decreased considerably and existing forests were broken into hundreds of segments, harming the biodiversity in the region. 

The third figure shows a summary of forest patch networks in central Chile during three study periods. PC is the probability of connectivity index.
