Inscription.  Areas of thick brush crown the high ground at Palo Alto. This dense vegetation-known as chaparral once covered much of the region. Development of the Rio Grande delta since the war has led to the removal of much of the chaparral. Today, sites like Palo Alto preserve portions of these rapidly-disappearing thickets.

Vast ranks of vegetation
During the U.S.-Mexican War, dense groves of mesquite, cactus and other brush extended for miles along the banks of the river. Many of these plants are of the acacia family, including the guajillo or acacia berlandieri, named in honor of Jean Luis Berlandier - a naturalist who also served in the Mexican army at Palo Alto.

Home on the range
The islands of brush that remain provide shelter to a number of animals that once roamed freely throughout the region.

A thorny foe
In 1846, the chaparral was so thick that the armies moved along narrow roads carved into the vegetation. Other times, soldiers struggled to cut their own paths through spiny thickets of plants like goat bush and lote bush.

Spanish:
Las áreas de maleza espesa coronan los terrenos elevados de Palo Alto. En otros tiempos, la densa vegetación - conocida como chaparral - cubría una gran parte de esta región. El desarrollo del delta del río Bravo desde los tiempos de la guerra ha llevado a la eliminación de la mayor parte del chaparral. Hoy en día, sitios como Palo Alto preservan porciones de estos matorrales que están desapareciendo rápidamente.

Vastos rangos de vegetación
En 1846, vastas bosquecillos de mesquite, cactus y otros arbustos se extendían por varias millas a lo largo de la ribera. Muchas de estas plantas pertenecen a la familia de las acacias, incluyendo al guajillo o Acacia berlandieri, así llamadas en honor de Jean Louis Berlandier - un naturalista que también sirvió en el Ejército Mexicano en Palo Alto.

Hogar en la pradera
Las islas de maleza que prevalecen ofrecen refugio a un número de animales que alguna vez deambulaban libremente por toda la región.

Un espinoso enemigo
En 1846, el chaparral era tan espeso que los ejércitos se desplazaban a través de estrechos caminos
