The common mulga (Acacia aneura) is the most abundant acacia of the hot arid interior of Australia. The name mulga comes from an aboriginal word meaning “long, narrow shield” and the strong wood was used to make weapons such as spears and boomerangs. Mulga is a small tree typically less than 20 feet tall with grey-green foliage and cylindrical sulphur yellow flowers favored by bees followed by flat brown seed pods high in protein.

Their scientific name means “Barking dog”.

This highly adaptable opportunistic omnivore seems to prefer rodents and jackrabbits, but will eat reptiles, birds, arthropods (scorpions, crickets) and plant material such as juniper seeds, screw beans, fan palm fruit and dates. A crepuscular and nocturnal hunter, they are valuable as rodent control. Their only predator is Man.

Coyotes are dog-like, sandy-colored, with erect ears. They roam extensively throughout their territory, hunting, resting and sleeping wherever they are comfortable, living in a den only when raising pups.

Coyotes usually mate for life and breeding takes place between January and March. The gestation period is 63 days and one litter per year of 1-12 pups (average 4 to 5), is born and raised in a den or rock crevice. Pups are born blind, but furred, will nurse for 5 to7 weeks and begin to leave den at 3 weeks, but it is 6 weeks before they really begin to run with their parents when they all abandon the den. If you see a group of 3-6 coyotes, it is most likely a mated pair and their young of the year, or perhaps a group of litter mates. Coyotes do not have large packs as some wolves do. Their potential lifespan in the wild is about 13 years and in captivity is 15-20 years. They do not make good pets.

Coyotes communicate using scent and body language as well as vocalization.

The local Arabic name for them is “edmi gazelle”.

Usually found in small herds, rarely exceeding seven individuals, it is the only surviving gazelle endemic to the area north of the Sahara Desert. Its coat is dark fawn in color with distinctive dark brown lateral bands, and dense due to the cold desert climate of its mountainous habitats. Both males and females have curved ridged horns.

It is herbivorous, sometimes living in areas of sparse vegetation, but will seek out cultivated fields, mainly feeding in morning and late afternoon on grasses, herbage and bushes. It can utilize water found in plants as well as dew. Man is now the main predator, but cheetah, leopard, lion, serval, caracal, jackal and eagles preyed on it in times past.

There are two calving seasons per year, from April to May and July to August, with births occurring after a gestation of approximately 160 days. Usually only one calf is born but there is a 40% chance of twinning with each pregnancy. They can live up to 12 years.

It can take anywhere from 8 to 20 years for this plant to store enough energy to send out a tall asparagus-like flower stalk with clusters of yellow flowers.

Also known as Waterweed, this is a water-indicating plant commonly found in seasonal streambeds.

Highlights

Bighorn sheep are specially designed for the unforgiving rocky mountain terrain they call home, from cloven hooves and use of vegetation for hydration to large domineering horns.

A bighorn sheep’s hooves are strong and split, which provide balance and grip as they forage for water-rich food, evade predators, or battle for dominance.

Males, called rams, have large, curled horns that are made of keratin. Their horns are used in battle with other rams, but also serve as a status symbol within the herd.

Bighorn sheep are threatened by disease, habitat degradation, care collisions, and habitat fragmentation due to urban and commercial development. The Living Desert actively supports the national conservation of this species through the leadership of the Species Survival Plan and local conservation efforts through collaborative efforts with local programs.

The oddly shaped pale yellow flowers provide generous amounts of nectar.
