Daintree Basin

The Daintree Basin has an area of 2,107km2 and has a high proportion of protected areas (56% natural/minimal use lands and 32% forestry). Remaining area consists of 7% grazing, 2% sugarcane, 1% urban and 2% other.

Steep mountains and hills dominate the Daintree basin, with a narrow coastal plain. The coastal lowland fringe is characterised by mangrove wetlands, sandy beaches and inshore fringing reefs. The majority of public and private land in the highlands is included in the Wet Tropics World Heritage Area, and there is a high level of tourism associated with the basins natural values

Water quality

Hover over each segment for indicator scores and data confidence.

A water quality overall score and grade cannot be provided for the Daintree basin in 2015-16 due to insufficient data. A new end of catchment water quality monitoring site is being established through the Paddock to Reef program, and the data will be made available for the Wet Tropics Report Card in future years.

Habitat and hydrology

Hover over each segment for indicator scores and data confidence.

The overall habitat and hydrology grade for the Daintree basin in 2014/15 is ‘very good’.

The habitat modification score of 100.0 (‘very good’) is comprised of an impoundment length score of 100.0 (‘very good’) indicating that less than 1% of the total length of the waterways with a stream order of 3 or higher are impounded by artificial structures.

The fish barrier indicator method is still being developed and will be available in future report cards.

Riparian extent for the Daintree basin scored 99.96 (‘very good’) with 0.01% loss from pre-clear extent to 2013, due to the basin predominantly being in the World Heritage Area.

Wetland extent scored 61.8 (‘good’) with 14.6% loss of palustrine (freshwater) wetlands from pre-clear to 2013. These results reflect a historic loss, with the Daintree wetlands largely intact in the upper catchment.

Habitat modification, riparian extent and wetland extent are updated every four years and have not changed since 2014-15. The data for riparian and wetland extent are due to be updated in 2018.

The invasive weeds indicator is new for the 2015-16 period and scored 62.6 (‘good’) in the Daintree basin.

The habitat and hydrology index score and grade differed between 2014-15 and 2015-16 due to the introduction of the invasive weeds indicator.

The method for the flow indicator is currently under development and will be available for future report cards.
