Aim: 
Investigated habitat preferences of Delma impar at multiple spatial scales
Type of Study: 
Pre-existing contrasts
Key Results: 
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).
Treatments: 
None
Response: 
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.
Models: 
P values, HGLMM
Locations: 
Various conservation areas in the ACT
Response variable : 
counts, species
Replication: 
23
Ecosystem: 
grassland
