Project SummaryTRC1 This project will explore the extent to which widely used measures of rangeland condition can also serve as surrogates for biodiversity status. Where currently used indicators prove inadequate, new indicators may need to be developed for use in monitoring critical or sensitive components of biodiversity. During the project, biodiversity attributes and measures of land condition will be sampled at sites ranging in condition, in three representative rangeland regions of northern Australia. The project will develop and validate mechanisms for biodiversity monitoring within rangelands, an important tool for improving adaptive management and ecological sustainable use of the rangelands.
