North Deer Island Restoration, 1

This is Passport to Texas

Eighteen species of birds rely on North Deer Island, near Galveston, for nesting habitat. Yet, over time, pounding waves caused by high winds and barge traffic eroded the shoreline of this natural rookery island.

Erosion really accelerated over the last four or five years. A rough estimate is [we lose] probably three to five acres a year.

That’s Bob Galloway—Houston Audubon Society’s Island Warden. Without intervention, it’s estimated the island, located next to the gulf intercoastal waterway, would decrease in size by 30% over the next 30 years. Coastal ecologist, Jamie Schubert.

This northeastern bluff is the most visually striking area of erosion. It’s been undermined by barge wakes and northerly storms blowing in waves that have undermined the bottom of the bluff and caused collapse at the top with these shrubs and other bushes falling down.

So, Audubon teamed up with Texas Parks and Wildlife and to protect the shoreline.

What this crew is doing is they’re constructing a rock breakwater, and it’ll trip the waves, reducing the wave energies that cause erosion on the island.

We’ll have more about that tomorrow.

That’s our show… with support from the Wildlife Restoration program…funding habitat restoration in Texas.
