Before Cattle: A Comparative Floristic Study of Eucalyptus Savanna Grazed by Macropods and Cattle in North Queensland, Australia

Before Cattle: A Comparative Floristic Study of Eucalyptus Savanna Grazed by Macropods and Cattle... ABSTRACT Floristic differences between cattle‐grazed and macropod‐grazed sites (protected from domestic stock by enclosure within a Holocene lava flow) were examined in Eucalyptus savanna in north Queensland, Australia. While macropod‐grazed sites have had a lower incidence of fire than the cattle‐grazed sites, it seems probable that grazing impacts per se are the major differences between these treatments. One dominant (Capillipedium parviflorum) and another common (Sehima nervosa) native perennial grass in the macropod‐grazed treatment were not recorded within the cattle‐grazed treatment. There was generally a lower species richness and Shannon‐Weaver diversity of perennial forbs in the cattle‐grazed treatment compared to the macropod‐grazed treatment. There was higher richness, diversity, and abundance of annual grasses in the cattle‐grazed treatment compared to the macropod‐grazed treatment.

Abstract

ABSTRACT Floristic differences between cattle‐grazed and macropod‐grazed sites (protected from domestic stock by enclosure within a Holocene lava flow) were examined in Eucalyptus savanna in north Queensland, Australia. While macropod‐grazed sites have had a lower incidence of fire than the cattle‐grazed sites, it seems probable that grazing impacts per se are the major differences between these treatments. One dominant (Capillipedium parviflorum) and another common (Sehima nervosa) native perennial grass in the macropod‐grazed treatment were not recorded within the cattle‐grazed treatment. There was generally a lower species richness and Shannon‐Weaver diversity of perennial forbs in the cattle‐grazed treatment compared to the macropod‐grazed treatment. There was higher richness, diversity, and abundance of annual grasses in the cattle‐grazed treatment compared to the macropod‐grazed treatment. The relative richness of native and exotic species was not significantly affected by cattle grazing.
