Cumberland Land Conservancy - Thornbill

Using citizen science to monitor climate change impacts in Western Sydney

This trail location is owned and accessed by the Cumberland Land Conservancy (CLC). Data for this trail can only be collected in cooperation with a CLC Supervisor. Please contact the CLC if your school or community group would like to arrange a visit for educational or scientific purposes, and help monitor and manage the reserve.

Acquired in 2017 by the Commonwealth Government and gifted to the Cumberland Land Conservancy, the property "Thornbill"  in Agnes Banks covers 2.2 ha of high conservation bushland and is part of a key corridor between Sydney University’s Richmond Campus and the Agnes Banks Nature Reserve.

The property protects Critically Endangered Shale-Gravel Transition Forest and Endangered Alluvial Woodland. The property also supports the Endangered Cumberland Plain Land Snail (Meridolum corneovirens), and several vulnerable plants. 

Key ClimateWatch indicator species monitored at this site include international migratory species such as the Eastern Koel and Channel-billed Cuckoo, plants such as the Sweet Bursaria (Bursaria spinosa subsp. spinosa), Black-anther Flax-lily (Dianella revoluta) and the Grey Box (Eucalyptus moluccana) of which psyllid outbreaks are being monitored as an indicator of woodland health. This particular species of Box is integral to Cumberland Plain Woodlands and an important source of nectar and pollen for bees, native insects and birds, including the Critically Endangered Swift Parrot (also monitored on ClimateWatch).

Earthwatch and the Cumberland Land Conservancy will be delivering a ClimateWatch training workshop in 2019 for teachers and community groups that would like to get involved in monitoring and restoring the Critically Endangered Shale Gravel Transition Forest and Endangered Alluvial Woodland.
