Discovering a quiet, secluded spot to lift chicks may be powerful for a beach-nesting fowl just like the Royal Tern, particularly as a lot of our coastlines are crowded with folks, buildings, boats, and different issues that make up coastal life for us people. Rookery islands like Chester Island, positioned 3 miles off the coast of Port O’Connor, Texas, present a secure area for birds to nest with fewer human disruptions or animal predators.
“Small islands are essential to birds alongside the coast of Texas,” says Alexis Baldera, coastal program supervisor for Audubon Texas, as a result of many species of North America’s long-distance migrating birds rely upon the Texas coast sooner or later of their lifetime.
Nonetheless, these islands are disappearing resulting from sea-level rise, erosion, and tropical storms. “We’re dropping slightly little bit of floor day by day,” says Baldera. “When there are fewer locations for birds to relaxation and nest, we’re going to have fewer birds—not simply in Texas however world wide.”
Chester Island is one in every of 200 islands that dot the Texas coast from Galveston to South Padre. These largely undeveloped islands are an oasis for birds dealing with an extended migration throughout the Gulf of Mexico, a spot to relaxation and gasoline up for his or her journey. That’s why Audubon Texas manages a majority of those islands and has developed an progressive new plan to gradual the erosion.
In 1986, when Chester Smith grew to become the brand new coastal warden of what was then a 200-acre island in Matagorda Bay, solely 5 pairs of Brown Pelicans had been nesting there. Their populations had been nonetheless wounded by the results of the pesticide DDT. At the moment, the island is dwelling to greater than 3,000 pairs of Brown Pelicans, plus different iconic species like Roseate Spoonbills and Reddish Egrets, totaling 20,000 nesting pairs every year. After a long time of devoted conservation Smith handed away in 2011, and since then the island has been named in his honor, together with his son-in-law Tim Wilkinson now watching over the island.
“I take plenty of satisfaction in doing this job,” says Wilkinson, coastal warden for Chester Island Chook Sanctuary at Audubon Texas. “I assume you would say it’s type of just like the household enterprise.”

The island is definitely human-made, created with sediment dredged from the close by Matagorda Ship Channel. Yearly across the U.S., large quantities of sediment are dredged from ports, harbors, and waterways to maintain them navigable for boats and ships. The byproduct of dredging is a great deal of wealthy sediment dug up from the water backside, a sizzling commodity for locations like Chester Island which can be dropping floor by the day. Audubon Texas has developed a plan with a number of companions to place this leftover dredged sediment to good use by restoring present islands and even including 5 solely new islands to the Texas mid-coast.
To attain this, a barge will decrease a suction dredge to the underside of Matagorda Bay to loosen the sediment and pump it to the floor. A pipeline transports the sediment, the place it is deposited on a brand new or present island. Building tools delivered to the islands assist form the added soil. Lastly, technicians plant vegetation on the brand new parcels of land to reduce erosion and create new habitat.
Audubon Texas lately acquired the Conservation Wrangler Award from Texan by Nature to help this monumental process. Collectively, Audubon Texas and Texan by Nature are serving to their fellow Texans perceive the significance of a wholesome Matagorda Bay to help the state’s ecotourism industries, defend our communities, and supply locations to benefit from the outside.
Joni Carswell, government director of Texan by Nature, says Audubon’s work in Matagorda Bay “represents among the easiest Texan-led tasks which have a optimistic impression to folks, prosperity, and pure assets in our state.”
The birds that nest on Chester Island—and the wealthy Matagorda Bay ecosystem the place it sits—are an important a part of Texas’s coastal id. Every winter, vacationers flock to the mid-coast to catch a glimpse of migrant species just like the Whooping Crane foraging in coastal bays and estuaries, contributing to the $1.8 billion Texas wildlife viewing economic system.
Defending and restoring islands like this across the nation is a vital part within the battle towards local weather change. Like a pace bump, islands decelerate wind and waves on the coast, buffering close by cities from incoming storm surge and sea-level rise. Islands additionally function carbon sinks, storing local weather change-causing carbon air pollution of their vegetation and soils.
“The underside line,” says Baldera, “is that the birds want these islands, and we want these islands.”
