Pine plantations and five decades of land use change in central Chile.

ABSTRACT: The expansion of forest plantations is cause for concern because of their environmental effects, and the loss of native forests and agricultural land. Our goal was to quantify the increase in pine plantation, and concomitant loss of native forests, in central Chile since ca. 1960, and to identify in which settings native forests were lost most rapidly. We analyzed aerial photographs from 1955 and 1961, Landsat images from 1975 and 1998, and Google Earth high-resolution satellite images from 2014. To ensure high classification accuracy, we visually interpreted images for a systematic 3-km grid and assigned each point as either 'pine plantation', 'native forest', 'agricultural-livestock lands', or 'other'. We also calculated latitude, longitude, slope, Euclidean distance to the nearest road
