North Deer Island Restoration, 2

This is Passport to Texas

[cacophony of birds] This is the ruckus you hear during spring and summer days on North Deer Island after its temporary residents—18 species of marine birds and their nestlings—set up housekeeping.

[backhoes limestone] For the past nine years, after the birds vacate in winter, the roar of backhoes spreading tons of limestone rubble along the rookery island’s shoreline replaced their calls. Coastal ecologist, Jamie Schubert.

They’re constructing a rock breakwater. And it will trip the waves, reducing the wave energies causing erosion on the island.

Pounding waves eroded the landmass, and without creating water breaks and additional nesting area, the future well-being of the island’s full-time and part-time inhabitants would be at risk.

We beefed up this side of the island with the dredge material and armored that with limestone rock. The barge wakes had kind of breeched this shoreline in here, so this project should allow this berm to reestablish with marsh vegetation, and give us a nice little marsh pond in here.

The island has been instrumental in the recovery of the Brown Pelican, and its wetland marshes provide valuable nursery habitat for shrimp, redfish and other important fish species. Preserving this rookery island means wildlife will always have a place in Texas to call home.

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