Most of the original, natural forests in the greater Taipei area have disappeared because of human activity. What remains today is mainly secondary natural forest. Yet even this is at risk: Many secondary natural woodlands have been destroyed by cutting for lumber or by clearance for illegal construction.
大台北地區的原生天然林便因人為介入而大多消失，如今多為次生天然林，即便如此，許多次生天然林也不斷遭到濫墾、違建等破壞。
