Mary River Catchment

FF
The Mary River catchment is a riverine floodplain of mixed grasses, sedges and herbs. In contrast to riverine woodlands, the habitat consists of mostly grassy landscapes. This environment is occasioned by huge granite boulders that rise out of the black soil plains. The Mary River catchment is unique in its status as a “nursery area” for many species found in Kakadu National Park. I first visited the area at the end of the dry when there was very little water and migratory birds were congested in dwindling billabongs. Now that the transition is from an abundance of water to wet soil grasslands those inhabitants are more residential.
