Tanglehead is a South Texas enigma in terms of its status as a native plant. For many years this grass was thought to be a climax component of sandy ecological sites, but this status, as well as questions about it origin have been questioned in recent years. Empirical evidence from across South Texas reveals a tremendous increase in tanglehead abundance over the last few decades. Tanglehead is a unique grass in that it has a world-wide distribution, and is considered noxious invasive plants in many areas including Hawaii and Australia. Tanglehead occurs in Africa alongside many of the same grasses that are problematic invasive plants in South Texas, including Kleberg Bluestem and Bufflegrass. Many range scientists hypothesize that tanglehead has increased in abundance in South Texas because of climatic patterns favoring tanglehead, and an overall reduction in stocking rates in areas where it occurs as a result of the economic value of wildlife. Genetic research is suggested as the best option for answering the questionable status of tanglehead in South Texas.
