Environmental Water Allocation required to sustain macroinvertebrate species in ephemeral streams

Project Objectives: To determine the key drought refuges used by macroinvertebrate species in intermittently-flowing streams and determine the level of threat to each refuge posed by prolonged drying and unpredictable flow regimes To determine the role played by different types of drought refuge in restocking macroinvertebrate populations in rivers and therefore the consequences for river communities of loss of each type of drought refuge. To determine the (more)...

Maximising woodlands bird diversity in Brigalow Belt forests

The Brigalow Belt is a national biodiversity hotspot, and its extensive forests and woodlands are potentially significant refugia for fragmentation-sensitive birds, but our understanding of optimal management for biodiversity conservation and the specific threats facing woodland birds in the area is limited. In particular, management of the aggressive noisy miner is a major challenge throughout the region, despite the species typically being associated with fragmented landscapes. This project aimed to (more)...

Frogs as bio-indicators of chemical useage and farm practices in an irrigated agricultural area

Dramatic declines and extinctions in frog populations worldwide and high frequencies of physical or reproductive abnormalities in frogs may be directly or indirectly related to agricultural activities among other factors. The causes of the declines in amphibian populations remain unresolved, but recent studies suggest six main hypotheses to explain them: habitat destruction chemical contaminants, particularly pesticides increasing (more)...

Identifying Groundwater Dependent Ecosystems

Groundwater dependent ecosystems (GDEs) are important elements in the landscape that require access to groundwater to maintain their health and vigour. They are important because of their conservation, biodiversity, ecological, social and economic value.

There are two threats to GDEs — outright loss of habitat and outright loss of groundwater resources.

How much habitat is enough?

Native animals are a distinctive part of the heritage of rural Australia. A sustainable environment is one in which the sights and sounds of Australia’s extraordinary wildlife will continue to be present and add to the quality of life for generations to

Managing the Bush

Testimonials: Rob and Lucy Adams - Swallowfield

Rob and Lucy Adams own and manage ‘Swallowfield’ and nearby ‘Tulloch’, which were purchased by Rob’s parents in 1970-73. This testimonial describes Rob and Lucy’s management of ‘Swallowfield’ and the many examples where they have been able to simultaneou

Birds on New England Wool Properties

Twenty species of woodland bird have been identified that are destined for extinction in the NSW wheat-sheep belt, where little habitat remains (Reid 1999). We found ten of these species on New England wool properties between 2002 and 2005.
