South Texas Ambrosia
The South Texas Ambrosia Bio
- U.S. Status
- Life History
While south Texas ambrosia does not appear to survive continual plowing, sporadic disturbance may enhance its growth and spread. Studies are currently addressing the effect of mowing on the species.
Loss of habitat has led to the decline of this species. Conversion of habitat to agricultural fields and urban areas has limited the amount of habitat available for colonization. In addition, introduced species such as buffelgrass and King Ranch bluestem compete with this and other natives of the coastal prairie. Invasion of grasslands by shrub and tree species also contributes to loss of available habitat, although the species does occur among scattered woody plants. Disturbance associated with activities occurring along road right-of-ways where the species is found may also be detrimental.
How to Help
Landowners and managers can help conservation efforts by learning to recognize this plant and managing the sites to maintain diverse native rangeland plant communities. Mechanical brush management and herbicide use should be carefully planned to avoid damaging impacts to colonies of south Texas ambrosia.
