Numurkah is a low lying town located on the floodplain of the
Broken Creek. The Broken Creek flows into the
Murray River just north of the township of
Barmah. The riparian area adjacent to the creek has a dominant over-storey of
Eucalyptus camaldulensis (red gum). Above the floodplain tree species include
Eucalyptus microcarpa (grey box),
Eucalyptus melliodora (yellow box) and
Callitris glaucophylla (Murray pine). There is a small roosting population of grey-headed flying foxes (
Pteropus poliocephalus)and little red flying foxes (
Pteropus scapulatus). These mega-bats are important pollinators of native tree species. Their diet is nectar, pollen, and fruit. The little red flying fox has translucent wings and eats nectar from flowers almost exclusively. Both have long tongues for getting deep into flowers. Numurkah also is home to many species of insect eating microbats (small bats) with the
Gould's wattled bat being the most common. These small bats live in tree hollows and play an important role in insect control eating large quantities of insects each night. Adjacent to the golf course, is also one of the easternmost remnants of the Northern Plains Grassland community known as the Numurkah Grassland. It is home to many native wildflowers and grasses such as billy button, small vanilla lily, everlasting etc. ==Natural disasters==
