The US Southeast Atlantic faces a high threat of sea level rise in the next 10 years – ScienceDaily



A new study shows that 75 percent of the Atlantic coast from North Carolina to Central Florida will be vulnerable to erosion and expansion from the tidal wave in 2030, which adversely affects many species habitats on the beaches.

The new data reflects a 30% increase in the region's most developed regions since 2000, the date of previous projections from the US Geological Survey.

The findings are from a study conducted in Log of wildlife management, Led by Betsy von Hall, a biologist at the University of Central Florida.

Some of the endangered coastal species include loggerhead and green sea turtles, endangered species and reeds along the coast have already faced challenges such as uptick in infectious diseases. According to the study, an increase in the sea level will increase the risk of erosion in about 50% of the nesting areas for these species until the next decade.

"We need to know not only which areas are going to be most affected by rising sea levels but also those species that are most vulnerable to sea level rise in order to understand management plans for coastal species," says von Hall.

Seabirds are no longer improving, according to the study. High density bird sea nesting along the coast for prey and seagull bound Sandwich Taran is expected to be approximately 80 and 70 percent increased risk of erosion and inundation from an increase in sea level by 2030, respectively.

Less brown pelicans are exposed to lower risk, according to a new study, with only 20 percent of their high-density habitats increasing the potential for ejaculation and erosion due to rising sea levels. This may be because they prefer nest in higher altitude areas, such as on artificially dredged islands.

"We are surprised that there have been so large differences in species in terms of vulnerability to sea level rise," says von Hall.

"When there is erosion and inundation during breeding seasons, it has great effects on species," she says. "Many of these species we have studied are threatened species and endangered, so only knowing that sea level rise will threaten some species in the future helps managers understand how to prioritize their management actions."

Although sea level rise poses a threat to coastal species, experts say so man-made structures, such as sea walls, as they prevent the coast from the natural and migratory inland. Without these types of structures, coastline and coastal sex can better match the rising days, as they did when faced with the threat in the past.

How they did it

To conduct the study, the researchers updated the US Geological Survey's vulnerability index for the South Atlantic, an area extending from Cape Hatters, North Carolina, to Sebastian Inlet, inward County, Florida, using the sea level rise forecast Data from multiple sources .

The area includes the Carr National Wildlife Refuge in the Rivers and Rivers River counties, one of the most important nesting habitats in the world, and the most important green nesting of green turtles in the United States.

Using the updated data, the region of the South Atlantic is considered very vulnerable to the effects of sea level rise from 45% in 2000 to 75% by 2030.

The researchers then lay down existing geographic data on the species' nesting density on vulnerability projections to determine the overlap between nesting species and the vulnerability to sea level rise in 2030.

They examined the habitat data for 11 animals, including three species of sea turtles, three species of root and five species of sea.

In addition to von Hall, the authors included Jennifer Lopez, Irish and Nick R. Taylor at Virginia Tech; Annette Spive with the University of Maryland; John P. Weishampel, a professor in the UCF Biology Department and Associate Dean of the UCF College of Graduate Studies; Anne Meilan with the Committee for the Conservation of Fish and Wildlife in Florida; Matthew G. Godfrey with the North Carolina Wildlife Resource Commission; Mark David with the Department of Natural Resources of Georgia; Sarah H. Schweitzer with the North Carolina Wildlife Resource Commission; Tim Keyz with the Department of Natural Resources of Georgia; Felicia Sanders with the Department of Natural Resources of South Carolina; Melissa K. Chaplin with the US Fish and Wildlife Service.

Von Hall received her doctorate in evolutionary ecology and biology from the University of Tennessee-Knoxville. She joined UCF in 2007.

The study was funded by the South Atlantic Landscape Conservation Cooperative.
