Predict what event is an example of geographic factors having a significant effect on buffalo in Texas?

Although this question is incomplete, we can still provide some information that can help guide your answer.

Buffalos (or bisons) were once a common sight in the American plains. While in the early 1800s about 60 million of these could be found across the country, the number was reduced to about 27 by the early 1900s. Government efforts have brought back this species from the brink of extinction.

While often associated with the American West, these animals lived in other regions of the country, including Texas. However, the buffalo population in Texas was not always regular. It varied based on several factors, including many geographic ones. For example, when rain was scarce, vegetation was hard to find. Water was also found in limited supply. This led the buffalo to migrate to other areas. Similarly, areas with fertile soil were used for agriculture, which made the land unavailable to the herds. These are examples of geographic factors that had a significant impact on buffalo in Texas.
