Headed west on FM 3005 across the San Luis Bridge, we quickly find ourselves in a stretch of Texas Coast that must look pretty much the same as when in 1785, José Antonio de Evia charted the coastline, naming the bay between island and mainland for Bernardo de Gálvez Gallardo, the viceroy of Mexico.
These grassy prairies are an open stretch of land that floods with rains and high tide. Submerged beds of widgeon grass provide food and shelter for crabs. When the water recedes, local wading birds scoop up the crabs as they climb out of their holes. Aquatic insects and crayfish are a great source of protein and live in abundance here. Safe nesting ground can be found in the rushes along the shorelines. This rich and fragile habitat is protected in various patches along the Gulf Coast. Brazoria National Wildlife Refuge is one of these conservancies.
