The Edwards Plateau region comprises an area of central Texas commonly known as the Texas Hill Country. It is a land of many springs, stony hills, and steep canyons. The region is home to a whole host of rare plants and animals found nowhere else on earth.

Average annual rainfall ranges from 15 to 34 inches, Rainfall is highest in May or June and September. Soils of the Edwards Plateau is honeycombed with thousands of caves. Beneath the eastern edge of the Plateau lies a hidden world of underground lakes known as the Edwards Aquifer. This precious water resource also is home to a number of curious creatures, such as the blind salamander.

Today, the Edwards Plateau is characterized by grasslands and savannahs were more common in pre-settlement times than they are today. Ranching is the primary agricultural industry in the region.

The Llano Uplift is also known as the central mineral region. Although surrounded by the Edwards Plateau region, the Llano Uplift is distinguished by its unique geology. Home to some of the oldest rocks in Texas, the central mineral region contains unique minerals and rock formations. the region is characterized by large granite domes, such as Enchanted Rock near Fredericksburg.

Rainfall averages about 24-32 inches per year, peaking in May or June and September. The landscape is rolling to hilly and elevation range from 825 to 2,250 feet above sea level. Soils are predominantly coarse textured sands, produced from weathered granite over thousands of years.

Native vegetation consists of oak-hickory or oak-juniper woodlands, mesquite-mixed brush savannah, and grasslands. Open grassland and savannah were once more common than they are today. Ranching is the predominant agricultural industry.
