Forest fragmentation as a function of the proportion of forest cover <i>PFC</i> in 10 x 10 km cells in Peninsular Spain.

<p>Forest fragmentation is quantified as the percentage of forest occurring in the largest patch, <i>rLPS</i>. The upper solid line delimitates cells with near zero fragmentation (<i>rLPS ≈</i>100%). The lower solid and discontinuous lines (95% CIs) correspond to a polynomial regression on 100 cells located at the lower edge of the cloud of points. We used this line to quantify maximum fragmentation in terms of <i>rLPS</i> at varying levels of <i>PFC</i> (see text). Note that <i>PFC</i> decreases to the right.
