Vegetation in the interior highlands is varied. Much of the western, southern, and central mountains are open woodland; supporting pine forest interspersed with some oak, scrub, and grassy clearings. The ranges toward the east are primarily continuous areas of dense, broad-leaf evergreen forest. Around the highest peaks, remnants of dense rainforest that formerly covered much of the area are still found.
