Collected Evidence: Collected Evidence: Regulate water levels One study evaluated the effects of regulating water levels on reptile populations. This study was in France. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One controlled, before-and-after study in France found that autumn–spring marsh flooding with moderate levels of grazing in autumn–winter led to higher numbers of European pond turtles than winter–spring flooding with high levels of grazing in spring–summer.

This study was in Australia. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One before-and-after study in Australia found that releasing a large flow of water into a wetland system had mixed effects on relative abundance of eastern long-necked turtles and the number of turtles caught. Condition (1 study): One before-and-after study in Australia found that after releasing a large flow of water into a wetland system, body condition of eastern long-necked turtles improved.

This study was in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (0 STUDIES) BEHAVIOUR (1 STUDY) Use (1 study): One replicated, before-and-after study in the USA found that after sediment removal, or dam maintenance along with sediment removal, one water impoundment was still used by Sonoran mud turtles and a second was not used.

This study was in the USA.
