Once again, Terry Liddick, pilot/biologist from our Migratory Birds program, served as a pilot, flying a U.S. Fish and Wildlife Service Cessna 206. This year Phil Thorpe also served as a pilot, flying a U.S. Fish and Wildlife Service wheeled Kodiak. Observers were Wade Harrell, Jena Moon (Refuges Inventory and Monitoring biologist), Doug Head (Refuges Inventory and Monitoring biologist) and Stephen LeJeune (Chenier Plains Refuge Complex Fire Program). Doug Head (Refuge Inventory and Management biologist) served as survey coordinator.

The U.S. Fish and Wildlife Service estimated 431 whooping cranes in the Aransas-Wood Buffalo population inhabited the primary survey area  for the winter of 2016–2017.

Survey results indicated 431 whooping cranes (95% CI = 371.1–492.7; CV = 0.101) inhabited the primary survey area (Figure 1). This estimate included 50 juveniles (95% CI = 36.3–60.9; CV = 0.144) and 162 adult pairs (95% CI = 139.2–185.5; CV = 0.100). Recruitment of juveniles into the winter flock was 13.1 chicks (95% CI = 10.4–16.6; CV = 0.119) per 100 adults, which is comparable to long-term average recruitment. The precision of this year’s estimate achieved the target set in the whooping crane inventory and monitoring protocol (i.e., CV < 0.10).

Whooping cranes return to Texas next month-so what did Harvey leave them?

Harvey

AUSTWELL — The panorama from the 40-foot observation deck at the Aransas National Wildlife Refuge is breathtaking. Stands of live oak dissolve to prairie grasses, which give way to coastal marshes en route to San Antonio Bay.

Look a little closer, though. There’s disorder amid the beauty.

A wooden platform has been blown or washed hundreds of yards away from its footing. A line of debris rings the brush along the service road, indicating the terminus of the storm surge. And nestled in the live oak grove, hundred-year-old trees with leaves stripped from their branches have been knocked over like bowling pins, their roots exposed.

“Nature’s resilient, and I know this area will recover,” refuge manager Joe Saenz said. “But the trees, once they’re gone, they’re gone. And trees here took a beating.”

The impact of Hurricane Harvey is everywhere — like it is in many places throughout Texas’ Gulf Coast. Here, the storm has placed the lone wintering ground for one of world’s most famous endangered species, the whooping crane, under threat.

The heart of the refuge, a 45,000-acre tract on the Blackjack Peninsula south of the tiny town of Austwell, is about 20 miles from the human tragedies found in Rockport, Port Aransas and Bayside. Harvey’s eyewall, bringing 130 mph winds, passed between those communities and the refuge more than two weeks ago.

Satellite imagery from the National Oceanic and Atmospheric Administration indicate a
good deal of beach erosion in another part of the refuge, on Matagorda Island, the barrier that protects the peninsula from the Gulf of Mexico. And as Saenz drives to the observation deck, he gestures to Dagger Point, a part of the shoreline that lost 20 yards from storm erosion.

Even so, things don’t look too bleak. At first glance, the marshes appear to be in good shape. And that’s crucial.

The marshes are the sanctuary for the whooping crane, and home to one of North America’s greatest successes in wildlife conservation.
