Although this question is incomplete, we can still provide some information that can help guide your answer.
Buffalos (or bisons) were once an abundant species that roamed the American plains. The number of buffalo decreased from about 60 million to a couple dozen between the early 1800s and the early 1900s. However, in recent years, 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. The number of buffalo in Texas varied based on several factors, including many geographic ones, such as rain and soil quality. 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.
