These woodlands are a medley of perfectly balanced colours - the charcoal sock of the Darwin woollybutts contrasts with its smooth shiny white trunk above, and in the dry season its heavy orange blossoms are repeatedly decorated with waves of Banded Honeyeaters and other nectarivores. The woollybutts are mixed with various bloodwoods, boxes and stringybarks, and preside over a diverse understorey of grasses including sorghum and spinifex, kerosene, wanderrie and love grasses, and cockatoo and ribbon grasses in damper areas. The seed from these grasses support a wide range of animals from ants to birds and small mammals. Frequent fire and grazing by large herbivores reduce grass seed yields, and this is at least partly responsible for the recent declines in species like the Gouldian Finch. Control of feral herbivores and fire will ensure the grass layer and seed-eating birds are protected.
