在1972年至1976年的筑巢季节期间，基亚瓦岛，南卡罗来纳州进行了调查Caretta caretta的筑巢活动。孵化场，从1973年至1976年的操作，减少了浣熊捕食对巢的影响，通常产生了高比例的孵化。从1973年到1976年，每晚的海滩巡逻有助于减少浣熊在海滩上的巢穴中捕食;在研究期间，偷猎鸡蛋的行为停止了。筑巢的女性被标记从1973年至1976年，以获得信息的大小，每年筑巢人口，在季节renesting，和internesting流浪。从1973年到1976年，筑巢活动的减少与任何特定的人类活动无关，自1976年以来似乎已经逆转。平均34.0？3.7每年都有成年和未成年的红海龟尸体被冲上岸。海龟死亡的发生与近岸沃茨密集的商业捕虾活动密切相关。基亚瓦岛正在作为一个度假胜地进行开发，但建设者已经遵循了许多管理建议建立相对于卡雷塔。这可以解释自1976年以来筑巢活动的稳定，并表明谨慎的海滩开发不需要抑制繁殖的Caretta。
Surveys of nesting activity of Caretta caretta were performed during nesting seasons from 1972 to 1976 on Kiawah Island, SC. A hatchery, operating from 1973-1976, reduced the effect of raccoon predation on nests and usually yielded a high percentage of hatchlings. Nightly beach patrols from 1973-1976 helped reduce raccoon predation among nests left on the beach; egg poaching ceased during the study period. Nesting females were tagged from 1973-1976 to obtain information on the size of the annual nesting population, in-season renesting, and internesting wanderings. A decline in nesting activity from 1973-1976 could not be correlated with any specific human activity, and appears to have reversed itself since 1976. An average of 34.0 ? 3.7 adult and adolescent loggerhead carcasses washed ashore each year. Occurrence of dead turtles was closely related to intensive commercial shrimping activity in nearshore waters. Kiawah Island is undergoing development as a resort, but the builders have followed many of the management recommendations established relative to Caretta. This could explain the stabilization of nesting activity since 1976, and indicates that prudent beach development need not inhibit reproduction by Caretta.
