Table 1: Number of patches, absolute (ha) <strong>and</strong> relative (%) areas for each l<strong>and</strong> cover class in Fragas do<br />

Eume Natural Park in 1957 <strong>and</strong> 2003. Net change (absolute <strong>and</strong> relative) in number of patches <strong>and</strong> area is<br />

also shown. <strong>Change</strong> values greater than 0 indicate gains, <strong>and</strong> those less than 0 indicate losses. * indicates<br />

that relative change was not calculated because that l<strong>and</strong> cover class was absent in 1957<br />
