Vulnerable African Sheep Thrive in Texas
29 Oct
Summary
- Introduced in 1957, aoudad now number over 30,000 in Texas.
- These sheep compete with native wildlife for habitat and food.
- Aoudad can transmit deadly diseases to native bighorn sheep.
Originally from northern Africa, aoudad sheep were introduced to Palo Duro Canyon, Texas, in 1957 for hunting purposes. Despite being listed as vulnerable by the IUCN with fewer than 10,000 individuals remaining in their native range, their population in Texas has surged. Current estimates suggest over 30,000 aoudad now inhabit various Texas regions, including the Edwards Plateau and Trans-Pecos.
These invasive animals are major competitors with native Texas wildlife, such as bighorn sheep and mule deer, for both habitat and food. Their ability to thrive in rough, rocky terrain similar to that preferred by bighorn sheep creates direct competition.
Additionally, aoudad can transmit diseases, like Mycoplasma ovipneumoniae, which can be deadly to native bighorn sheep, hindering reintroduction efforts. While the full ecological impact is still under investigation, monitoring and containment are crucial, especially in areas where native species are being reintroduced.
