Aim: 
Investigated the potential of a trait-based approach to predict the preference of birds utilizing the grassy layers for different levels of grazing by eastern grey kangaroos within grassy habitats in south-eastern Australia.
Type of Study: 
Pre-existing contrasts
Key Results: 
Birds that utilized the grassy layer showed a varied response to differences in grazing intensity. Ground foragers, species with elevated nests, and birds that rely on early detection of predators were more likely to utilize the grassy layer under high grazing intensities. In contrast, small aerial insectivores, and a single ground-nesting species (that relies on concealment to avoid predators) were more likely to utilize grassy layer under lower grazing intensities.
Treatments: 
None
Response: 
Landscapes should contain a heterogeneous mosaic of grazing intensities.
Models: 
P values, HGLMM
Locations: 
Various conservation areas in ACT, NSW and Victoria
Response variable : 
occupancy, species, species richness
Replication: 
127
Ecosystem: 
grassland and grassy woodland
