What is the "Lowcountry" as noted in the nonfiction book, Wandering in Strange Lands?

The Lowcountry refers to specific regions of Georgia and South Carolina. There are many Black American communities in these regions, including various substantial Gullah Geechee populations. Many Gullah Geechee communities are located on coastal islands in these regions, and these communities are unfortunately being gradually displaced by the economic encroachment of corporations and wealthy white people.
