The establishment of irrigated farmland has formed perennially moist areas of cumbungi and native wetland grasses, which support larger numbers of several bird species than does the surrounding non-irrigated bushland and dry pasture.
[1] The irrigation and drainage infrastructure was constructed in the early 1960s, with commercial farming taking place from 1963 when Kununurra's Ord Diversion Dam was completed.
Farm blocks are typically 260-360 ha in size, on heavy, black cracking clay soils.
[1] The IBA supports the largest recorded numbers of star finches and yellow-rumped munias, as well as smaller number of Australian bustards, Bush stone-curlews, white-gaped and yellow-tinted honeyeaters, white-browed robins, masked and long-tailed finches, and sometimes over 1% of the population of Australian pratincoles.
Letter-winged kites, white-quilled rock-pigeons, varied lorikeets, northern rosellas, bar-breasted and banded honeyeaters are occasionally recorded.
