NPS (public domain) All In a NameTuna is the Spanish word for the fruit of the prickly pear cactus. This cactus is well known for its colorful blooms which come in shades of yellow, orange, peach, and red. When the blooms fade, the sweet fruits or tunas develop. The pads, also known as nopalitos, are edible as well - once the spines have been removed. Both of these items can be found at local grocery stores. A Growing PresenceAlthough native to the region, the cactus is more common now than in the past. The spread of prickly pear at Palo Alto is the result of decades of activities such as cattle ranching and ground clearing. 
NPS (public domain) South Texas StalwartMesquite trees and South Texas go hand in hand. The rugged plant is one of the few trees that do well in the area's hot, dry climate. When the trees are young they are flexible enough to bend in the coastal winds. Their sharp thorns protect them from grazing animals. As the trees mature, their trunks and branches grow rigid and dense. Battlefield EncroachmentToday, numerous dense pockets of mesquite dot the battlefield. This was not the case in 1846. The battlefield then was an open prairie, a perfect place for an artillery battle. Over the years, activities like cattle ranching have helped mesquite spread onto the prairie. The park is currently working on a mesquite management plan in the hopes of restoring the battlefield to its original state.
