\end{center}
The Texas Horned Lizard (\textit{Phrynosoma cornutum}) is a reptilian that is native to many areas of the south and can be found in much of both general Texas and East Texas. The Texas Horned Lizard is a brown and white lizard with black eyes and is becoming an endangered species in the previously mentioned areas. The animal was listed on the endangered species list in 1977, and many efforts are being made to keep the species alive.

\textsc{\RN{2}. Why is the Texas Horned Lizard Endangered?}
\end{large}
\end{center}
While there is not one sole factor for the endangered status of the species, the main contributing factors to the species endangerment is habitat loss, over collection, and pesticide use. There is also the possibility of of fire ants also playing a role in its endangerment.

\textsc{\RN{3}. The Fight for the Species}
\end{large}
\end{center}
While many people may not be aware of how serious the issue of the endangered species is, the Texas Horned Lizard Reintroduction Project has begun at the San Antonio Zoo, and they are looking to be able to bring back the species out of endangerment status, by working with private landowners to have them breed, promoting ecotourism, and getting funding to make the mission possible.

\textsc{\RN{4}. The Effects of the Extinction of This Species}
\end{large}
\end{center}
There are effects that will be found with the extinction of the Texas Horned Lizard. Firstly, the state of Texas will lose an animal with a cultural tie to it, and it will be of much loss if it were to disappear. Secondly, the harvester ant (\textit{Pogonomyrmex rugosus}) population would explode, and there would be no consumer to keep its population in check. Lastly, they provide biodiversity to the ecosystem they are a part of, and if gone, this can bring forth a huge effect on the ecosystem.

\textsc{\RN{5}. Conclusion}
\end{large}
\end{center}
The Texas Horned Lizard is still classified as endangered, and this is happening for many reasons. While there are many factors responsible for the endangered status that it is in right now, many things are being done to reverse the process. Human intervention plays a big role in helping the population make a comeback, and there are many groups/organizations helping the species repopulate.
