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:
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.
Landscapes should contain a heterogeneous mosaic of grazing intensities.
