Barrier islands along the Texas Coastal Zone are part of a complex and dynamic system represented by many distinct yet interrelated environments affected by a variety of resources, natural processes, climatic conditions, and human activities.

The Texas Coastal Zone is marked by diversity in geography, resources, climate, and industry.

Historical monitoring along Mustang and north Padre Islands records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.

Sequential shoreline monitoring, using vintage chans and aerial photographs, documents temporal and spatial variations in historical Gulf shoreline changes.

The Texas Coastal Zone is marked by diversity in geography, resources, climate, and industry.
