===Flora===
The complex geology, climate, fire regime, and topography has enabled a wide variety of ecosystems to develop. Eucalypt forest with western plain species, such as [[Eucalyptus melliodora|yellow box]] and [[Eucalyptus albens|white box]], are found in areas of rainshadow. Forests of [[Eucalyptus regnans|mountain ash]] are found on well drained soils and [[Eucalyptus blaxlandii|Blaxland's stringybark]] where soil is poor. [[Corymbia mannifera|red spotted gum]], [[Eucalyptus blakelyi|Blakely's red gum]], [[Eucalyptus macrorhyncha|red stringybark]] and [[Allocasuarina torulosa|forest oak]] are also found. [[Brachychiton|Kurrajong trees]] are found in abundance where limestone outcrops occur, and in sheltered gullies rainforest species (including [[Toona ciliata|red cedar]]) and [[Eucalyptus saligna|blue gum]] are found. On the Boyd Plateau, the misty mountain forests of [[brown barrel]], [[messmate]], [[Eucalyptus viminalis|ribbon gum]], [[Eucalyptus stellulata|black sally]], [[snow gum]] and mallee predominate. High altitude areas subject to strong winds generally support heath and closed scrub communities. In areas of impeded drainage, various swamps occur, dominated by sedges and scrubs such as ''[[Leptospermum]]'' and ''[[Baeckea]]'' species.<ref name=colong/>

About 1,000 flowering plant species occur in the Blue Mountains, in some 40 plant communities. There are over 45 rare or endangered plant species in the wilderness. A unique form of tall open forest occurs in the Kedumba Valley, dominated by [[Eucalyptus benthamii|Camden white gum]], an endangered species limited to these populations.<ref name=colong/>
