Cumberland Land Conservancy - Marsdenia

Using citizen science to monitor climate change impacts in Western Sydney

Acquired in 2017 by the Commonwealth Government and gifted to Cumberland Land Conservancy the property "Marsdenia" in Llandilo covers 3.75 ha of high conservation bushland and is part of a key corridor between the Wianamatta Regional Park and the Wianamatta Nature Reserve.

The property protects Critically Endangered Cumberland Shale Hills Woodlands and supports a healthy population of Marsdenia viridiflora subsp. viridiflora, a rare population listed as an endangered under the NSW Biodiversity Conservation Act 2016.

The property is located within the BirdLife Australia's Richmond Woodlands Key Biodiversity Area which protects the critically endangered Regent Honeyeater and Critically Endangered ClimateWatch species, Swift Parrot.

Other 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 Cherry Ballart (Exocarpos cupressiformis), Sweet Bursaria (Bursaria spinosa subsp. spinosa), Black-anther Flax-lily (Dianella revoluta) and the dominant 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 the 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 Cumberland Plain Woodland.
