Research - Jenolan Flora
Jenolan can be generally regarded as a cold climate, experiencing occasional snow falls, on occasions quite late into the year. Consequently the flora of the on the ridges and the upper slopes tend to be cold loving types. Deeper into the valley the gullies become sheltered which allows plants which require warm and moist conditions to thrive. The areas around cave entrances in particular enjoy warm moist air which is expelled from the caves, providing a remarkably consistent environment.
This photo shows vegetation that is typical of the ridgetops. When rain falls on this area the moisture is quickly drawn into the soil, leaving the surface dry very quickly.

This photo was taken on the valley floor just above the creekbed. In contrast to the ridgetops the vegetation here is much more dense. Although the soil will dry out, it is usually more moist than higher in the hills. Ferns, mosses and nettles are commonly found in the most moist areas.
