Chief refuge value
Significant dry season refuge for freshwater fish in the west Kimberley.
Three permanent pools on the Lennard River within Windjana Gorge. The pools are 500-800m long and up to 100m wide; the Gorge cliffs rise 30-100m above the dry-season waterlevel. It is part of a 5 km gorge cut by the River through the Napier Range. Fringing forest along the river includes cadjeput Melaleuca leucadendron, river gums Eucalyptus camuldulensis, and the figs Ficus racemosa, F. coronulata, F. hispida, and Nauclea orientalis. White cedar Melia azedarach, boabs Adansonia gregorii, Gyrocarpus americanus and Atalya hemiglauca occur on slopes of the Gorge.
Other significant species
Of 19 species of waterbirds recorded, three are listed under treaties; there are relatively low numbers1, 2, 3. Freshwater crocodiles Crocodylus johnstoni occur, as well as 14 species of freshwater fish, including bony bream Nematalosa erebi, spangled perch Leiopotherapon unicolor and archerfish Toxotes oligolepsis. See Williams for freshwater fauna of the area4.
