There is a high level of
biodiversity among plants and animals, with some species threatened by various factors. Only around 4.6% of the Little Sandy Desert bioregion is within a
protected area, much of which is managed as an
Indigenous Protected Area, the
Birriliburu Indigenous Protected Area (IPA), which stretches into the Gibson Desert, meaning that the land is looked after by its traditional owners. Most of the area is covered by
hummock grasslands (
Triodia spp.), with a few
eucalypts,
acacias,
grevilleas, and bloodwoods (
Corymbia chippendalei) are found on sand hills. As of 2020 over 2000 plant taxa have been identified, with only two of these recognised as
threatened species; over 550 of these are in the southern LSD, including 16 species of conservation significance. The bark of the
birdflower is used by local people to make belts and sandals, while the
spear tree is used for making spears for men and
digging sticks for women. There are many reptiles and birds species, but many small- to medium-sized mammals have gone extinct, and many are threatened. There have been 103 bird species recorded in the Birriliburu IPA, and 116 within the whole desert, including the
Australian bustard (
Aredeotis australis) and
bush stone-curlew (
Burhinus grallariu). Threatened animal species include: •
Greater bilby •
Princess parrot •
Kakarratul/northern marsupial mole • Australian bustard •
Brush-tailed mulgara •
Grey falcon Threats to biodiversity include
wildfires,
feral animals, weeds, and uncontrolled grazing.
Feral camels destroy water sources, and along with donkeys, horses and rabbits help destroy the ecosystem by overgrazing.
feral cats have reduced the populations of
bilbies and
mulgara.
Foxes are the main threats to mammals.
Buffel grass threatens the native plant species, as it is tough, and burns hotter in the ever more frequent bushfires caused by
climate change.
Bush Heritage Australia has done some plant and animal surveys in
Katjarra. ==Bioregion==
