Relationship With Humans
In Maryland, diamondback terrapins were so plentiful in the 18th century that slaves protested the excessive use of this food source as their main protein. Late in the 19th century, demand for turtle soup claimed a harvest of 89,150 pounds from Chesapeake Bay in one year. In 1899, terrapin was offered on the dinner menu of Delmonico's Restaurant in New York City as the third most expensive item on the extensive menu. A patron could request either Maryland or Baltimore terrapin at a price of $2.50. Although demand was high, over capture was so high by 1920, the harvest of terrapins reached only 823 pounds for the year.
According to the FAA National Wildlife Strike Database, a total of 18 strikes between diamondback terrapins and civil aircraft were reported in the US from 1990 to 2007, none of which caused damage to the aircraft. On July 8, 2009, flights at John F. Kennedy Airport in New York City were delayed for up to one and a half hours as 78 diamondback terrapins had invaded one of the runways. The turtles, which according to airport authorities were believed to have entered the runway in order to mate, were removed and released back into the wild. A similar incident happened on June 29, 2011, when over 150 turtles crossed runway four, closing the runway and disrupting air traffic. Those terrapins were also relocated safely.
Many human activities threaten the safety of diamondback terrapins. The terrapins get caught and drown in crab nets that humans put out, are suffocated by pollution that humans greatly contribute to, and lose their marsh and estuarine habitats because of urban development.
