Investigated habitat preferences of Delma impar at multiple spatial scales
Type of Study:
The occurrence of Delma impar was not affected by the size of grassland remnants, but was negatively related to the density of native grazers. This result was likely a consequence of the negative effect of high grazing intensity on grass structural complexity, as the probability of encountering a Delma impar was positively related to grass structural complexity at the fine scale (1m2).
Conservation efforts should avoid high intensity grazing (equivalent to>1.3 kangaroos/ha), yet ensure enough grazing disturbance is maintained to promote the formation of complex grass structures.
