Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Restore island ecosystems Three studies evaluated the effects of restoring island ecosystems on reptile populations. One study was in each of the Seychelles, the USA and the US Virgin Islands. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (3 STUDIES) Occupancy/range (1 study): One study in the US Virgin Islands found that following translocation to a restored island, St. Croix ground lizards expanded their range during the fifth to seventh year after release. Reproductive success (2 studies): One study in the Seychelles found that following a range of interventions carried out to restore an island ecosystem, the number of hawksbill and green turtle nests increased. One replicated study in the USA found that during and after an island was rebuilt, diamondback terrapins continued to nest on the island.

One study was in each of South Africa, China, Australia and the USA. COMMUNITY RESPONSE (2 STUDIES) Richness/diversity (2 studies): One replicated, controlled study in Mongolia found that areas of restored grassland had similar species richness compared to unrestored areas. One replicated, site comparison study in South Africa found that an area of restored grassland had lower species richness than natural grassland in three of four comparisons. POPULATION RESPONSE (3 STUDIES) Abundance (3 studies): One of two replicated, controlled studies (including one paired study) in Mongolia and the USA found that areas of restored grassland had higher lizard abundance than unrestored areas. The other study found that areas of restored grassland had fewer snakes than unrestored areas. One replicated, site comparison study in South Africa found that an area of restored grassland had a similar abundance of reptiles compared to two areas of natural grassland. BEHAVIOUR (1 STUDY) Use (1 study): One replicated, randomized, controlled study in Australia found that some areas of restored grassland and rocky outcrops were recolonized by pink-tailed worm-lizards.

This study was in Australia. COMMUNITY RESPONSE (1 STUDY) Richness/diversity (1 study): One before-and-after study in Australia found that reptile species richness was higher following restoration of savanna-like habitat on a golf course.

Three studies were in the USA, two were in Australia and one was in Mexico. COMMUNITY RESPONSE (3 STUDIES) Richness/diversity (3 studies): One of two replicated studies (including one randomized, controlled study) in the USA and Australia found that restored and natural riparian forest had similar reptile species richness. The other study found that restored forest areas had higher reptile species richness than remnant forest areas. One replicated, site comparison study in Australia found that the type of restoration had mixed effects on reptile species richness in tropical and subtropical areas. POPULATION RESPONSE (5 STUDIES) Abundance (5 studies): Two of three replicated studies (including two controlled, before-and-after studies) in the USA and Mexico found that areas of restored forest had similar abundances of snakes and six lizard species as unrestored areas. The other study found that restoring forest stands had mixed effects on the abundance of reptiles. One replicated, site comparison study in Australia found that areas with different restoration types had similar reptile abundance in tropical and subtropical areas. One replicated, randomized, controlled study in Australia found that restored forest areas had higher reptile abundance than remnant forest areas.

This study was in Mexico. COMMUNITY RESPONSE (1 STUDY) Richness/diversity (1 study): One replicated, controlled study in Mexico found that areas of restored shrubland had similar reptile and amphibian species richness compared to areas that were not restored. POPULATION RESPONSE (1 STUDY) Abundance (1 study): One replicated, controlled study in Mexico found that areas of restored shrubland had a higher abundance of lizards than areas that were not restored.

This study was in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Reproductive success (1 study): One controlled, before-and-after study in the USA found that removing beach debris from one section of beach did not increase nesting success in that section. BEHAVIOUR (1 STUDY) Use (1 study): One controlled, before-and-after study in the USA found that after the removal of beach debris from one of three beach sections, a higher percentage of both the total nests laid and failed nesting attempts occurred in that section.

Both studies were in the USA. COMMUNITY RESPONSE (1 STUDY) Community composition (1 study): One site comparison study in the USA found that restored and pristine streams had similar turtle community composition. POPULATION RESPONSE (2 STUDIES) Abundance (2 studies): One site comparison study in the USA found that restored and pristine streams had a similar abundance of turtles. One replicated, site comparison study in the USA found that creating new waterways by redirecting flows during forest restoration had mixed effects of reptile abundance.

Six studies were in the USA and one was in Kenya. COMMUNITY RESPONSE (3 STUDIES) Richness/diversity (3 studies): One before-and-after, site comparison study in the USA found that reptile species richness and diversity tended to be lower in a restored wetland compared to an undisturbed wetland. One replicated, site comparison study in the USA found that created, restored, enhanced and natural wetlands had similar combined reptile and amphibian species richness. One site comparison study in the USA found that created wetlands and adjacent natural forest had similar reptile species richness and diversity. POPULATION RESPONSE (2 STUDIES) Reproductive success (2 studies): One site comparison study in the USA found that a created wetland was used by snapping turtles for egg laying. One before-and-after, site comparison study in the USA found that in a restored wetland, 16 snake, six lizard and eight turtle species successfully reproduced. BEHAVIOUR (4 STUDIES) Use (4 studies): One site comparison study and three before-and-after studies (including one replicated study) in the USA and Kenya found that created or restored wetlands were used by black rat snakes and snapping turtles, turtles, lizards, green grass snakes and terrapins, six or 18 reptile species.
