Conserving remnants of endangered bonewood scrub and the vulnerable ooline tree, Nuga Nuga National Park is part of an island of unique and varied vegetation in a heavily cleared landscape.

Nuga Nuga National park preserves remnants of endangered bonewood Macropteranthes leichhardtii scrub and the vulnerable ooline Cadellia pentastylis, which are significant values of the Southern Brigalow Belt.

Lake Nuga Nuga is the largest natural water body within the Central Queensland Sandstone Belt and provides valuable habitat for water birds in an otherwise arid sandstone landscape. Water lillies on the lake flower at certain times of the year and the lake is dappled with colour providing visitors with photographic opportunities. The lake completely dries up at certain times.
