Habitat and Ecology
This species is an annual plant up to 20 cm tall, erect or ascending which grows in shallow sand over outcropping limestone, and in compacted bare ground and pan margins on calcrete, often forming mats. Tragus
species occur frequently as weeds throughout tropical and subtropical regions of the world, but so far only a few species have been introduced in America.

Scott, J.A. Contributor/s Justification
is assessed as Least Concern. The species is an annual grass which occurs only in Botswana and Namibia. The distribution range appears to be relatively restricted, although it doesn't meet the thresholds for a threat rating using criterion B and the species has been always recorded as abundant and usually forming mats in Namibia. It is believed that the threats are not significant enough to warrant concern at present. The species needs to be monitored over a longer period of time to make sure that it doesn't fall into a threatened category.
This species has been always recorded as abundant in Namibia (Grootfontein and Simkue areas). Population Trend
There are no known threats for the species. Human population is fairly low in the Kalahari Acacia-Baikiaea woodlands ecoregion (Spriggs 2001). The main threat to the area is the cattle-grazing industry, but it is not known whether this species might be threatened from overgrazing.
There are no known conservation measures specifically for this species, but it is known to grow in some protected areas.
