Webb County, Texas in the context of Starr County, Texas

Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing.

Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903.

Laredo (English pronunciation: /ləˈɹeɪdoʊ/ ; Spanish pronunciation: [laˈɾeðo] ) is a city in the U.S. state of Texas and the county seat and largest city of Webb County, on the north bank of the Rio Grande in South Texas, across from Nuevo Laredo, Tamaulipas, Mexico. Founded in 1755, Laredo grew from a village to the capital of the short-lived Republic of the Rio Grande to the largest inland port on the Mexican border. Laredo's economy is primarily based on international trade with Mexico, and as a major hub for three areas of transportation: land, rail, and air cargo. The city is on the southern end of I-35, which connects manufacturers in northern Mexico through Interstate 35 as a major route for trade throughout the U.S. It has four international bridges and two railway bridges.

According to the 2020 census, the city's population was 255,205, making it the 11th-most populous city in Texas and third-most populated U.S. city on the Mexican border, after San Diego, California, and El Paso, Texas. Its metropolitan area is the 178th-largest in the U.S. and includes all of Webb County, with a population of 267,114.
