Collected Evidence: Collected Evidence: Translocate bumblebee colonies in nest boxesWe have captured three small trials in the 1950s and early 1960s testing the effect of translocating bumblebee colonies in nest boxes. Two trials in Canada provided evidence of queen death and one of these showed lower colony productivity following translocation. Just one, a UK trial, concluded that early bumblebee Bombus pratorum colonies adapt well to being moved.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F53https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F53Thu, 20 May 2010 01:34:59 +0100Collected Evidence: Collected Evidence: Translocate birds away from fish farmsA study from the USA cited in a review found that translocating birds away from a fish farm appeared to reduce the number of birds at the farm. A study from Belgium found that translocating herons did not seem to be an effective way to reduce bird numbers at fish farms.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F251https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F251Wed, 18 Jul 2012 12:15:27 +0100Collected Evidence: Collected Evidence: Translocate individualsA review of 239 bird translocation programmes found 63–67% resulted in establishment of self-sustaining populations.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F566https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F566Sun, 30 Sep 2012 12:46:30 +0100Collected Evidence: Collected Evidence: Translocate auksA replicated study in the USA and Canada found that 20% of 774 translocated Atlantic puffins Fratercula arctica remained in or near the release site, with up to 7% breeding.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F570https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F570Sun, 30 Sep 2012 13:02:20 +0100Collected Evidence: Collected Evidence: Translocate gamebirds Three studies from the USA found that translocation of gamebirds resulted in population establishment or growth, or an increase in lekking sites. Four studies from the USA found high survival of translocated birds, although one, from Alaska found that translocated birds had high initial mortality, which then fell to levels close to those in resident birds. Two studies from the USA found high mortality in translocated birds. Four studies from the USA found breeding rates that were high, or similar to resident birds, amongst translocated birds.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F572https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F572Sun, 30 Sep 2012 13:50:44 +0100Collected Evidence: Collected Evidence: Translocate herons, storks and ibisesA before-and-after study in the USA found that a colony of black-crowned night herons Nycticorax nycticorax was successfully moved, with the new colony producing chicks the year after translocation.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F575https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F575Sun, 30 Sep 2012 14:25:50 +0100Collected Evidence: Collected Evidence: Translocate amphibians Overall, three global reviews and one replicated, before-and-after study in the USA found that 35 of 54 (65%) amphibian translocations that could be assessed resulted in established breeding populations or substantial recruitment to the adult population. A further two translocations resulted in breeding and one in survival following release. One review found that translocations of over 1,000 animals were more successful, but that success was not related to the source of animals (wild or captive), life-stage, continent or reason for translocation.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F854https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F854Fri, 06 Sep 2013 11:49:37 +0100Collected Evidence: Collected Evidence: Translocate great crested newts Four of six studies (including one review and one replicated study) in the UK found that translocated great crested newts maintained or established breeding populations. The review found that populations were present one year after release in 37% of cases and one study found that although translocations maintained a population in the short term, within three years breeding failed in 48% of ponds. One systematic review of 31 great crested newt studies found that there was no conclusive evidence that mitigation that included translocations resulted in self-sustaining populations. One review in the UK found that great crested newts reproduced following 56% of translocations, in some cases there was also release of head-started larvae and/or habitat management.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F858https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F858Fri, 06 Sep 2013 13:32:49 +0100Collected Evidence: Collected Evidence: Translocate frogs Eight of ten studies (including five replicated studies) in New Zealand, Spain, Sweden, the UK and USA found that translocating frog eggs, juveniles or adults established breeding populations at 100% or 79% of sites. Two found that breeding populations of two species were initially established but went extinct within five years or did not establish. Five studies (including one replicated study) in Italy, New Zealand and the USA found that translocated juveniles or adults survived the winter, had high survival, survived up to two years, or up to eight years with predator exclusion. One study in the USA found that survival was lower for Oregon spotted frogs translocated as adults compared to eggs and lower than that of resident frogs. Five studies (including three replicated studies) in Canada, New Zealand and the USA found that translocations of eggs, juveniles or adults resulted in little or no breeding at one or three of four sites. Two studies (including one before-and-after study) in the USA found that 60–100% of translocated frogs left the release site and 35–73% returned to their original pond within 1–32 days. Two before-and-after studies New Zealand and the USA found that frogs lost weight during the 30 days after translocation or became heavier than animals at the donor site.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F861https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F861Fri, 06 Sep 2013 14:31:31 +0100Collected Evidence: Collected Evidence: Translocate bats Two studies evaluated the effects of translocating bats on bat populations.

Survival (1 study): One study in Switzerland found that four of 18 bats died after translocation. Condition (1 study): One study in New Zealand found that lesser short-tailed bats captured at release sites eight months after translocation were balding and had damaged, infected ears. BEHAVIOUR (2 STUDIES)   Uptake (2 studies): Two studies in New Zealand and Switzerland found that low numbers of bats remained at release sites after translocation. Behaviour change (1 study): One study in Switzerland found that bats homed after release at translocation sites less than 20 km from their original roosts.

Three before-and-after studies in Tanzania, French Guiana, and Madagascar found that a majority of primates survived for 5-30 months following translocation from a development site to natural habitat, alongside other interventions. One study in French Guiana found that a minority of primates survived for at least 18 months. One before-and-after study in India found that rhesus monkeys remained at the sites where they were released following translocation from a development site to natural habitat, alongside other interventions.

Both were in Strangford Lough (UK).   COMMUNITY RESPONSE (2 STUDIES) Overall community composition (2 studies): One replicated, site comparison study in Strangford Lough found that plots with translocated mussels had different associated invertebrate communities to plots without mussels, but also to natural mussel beds. One replicated, controlled study in Strangford Lough found that translocating mussels onto scallop shells or directly onto the seabed led to similar associated invertebrate communities. Overall richness/diversity (2 studies): One replicated, site comparison study in Strangford Lough found that plots with translocated mussels had higher richness and diversity of associated invertebrates to plots without mussels, and similar to natural mussel beds. One replicated, controlled study in Strangford Lough found that translocating mussels onto scallop shells or directly onto the seabed led to similar richness and diversity of associated invertebrates. POPULATION RESPONSE (2 STUDIES) Overall abundance (2 studies): One replicated, site comparison study in Strangford Lough presented unclear abundance results. One replicated, controlled study in Strangford Lough found that translocating mussels onto scallop shells or directly onto the seabed led to higher abundance of associated invertebrates in one of two comparisons.

One was in Tayabas Bay (Philippines) and one in the South China Sea (Philippines).   COMMUNITY RESPONSE (2 STUDIES) Overall community composition (1 study): One replicated, controlled, before-and-after study in the South China Sea found that following coral translocation associated invertebrate communities did not change and remained similar to plots without translocated corals. Overall richness/diversity (2 studies): One replicated, controlled, before-and-after study in the South China Sea found that following coral translocation richness of associated invertebrates increased but also increased in plots without corals, likely due to spill-over. One replicated, controlled study in Tayabas Bay found that richness of associated invertebrates was higher in plots with translocated corals than in plots without. POPULATION RESPONSE (1 STUDY) Overall abundance (1 study): One replicated, controlled, before-and-after study in the South China Sea found that following coral translocation abundance of associated invertebrates increased and became higher than in plots without translocated corals.

Three studies were in Germany and one was in Hungary. VEGETATION COMMUNITY (3 STUDIES) Characteristic plant richness/diversity (3 studies): Two of three replicated, controlled studies (including two randomized studies, one of which was paired) in Germany and Hungary found that transferring hay alongside sowing seeds did not alter target grass and forb species richness. The other study found that transferring hay alongside sowing seeds increased the species richness of target plants. VEGETATION ABUNDANCE (3 STUDIES) Characteristic plant abundance (3 studies): Two of three replicated, controlled studies (including two randomized studies, one of which was paired) in Germany and Hungary found that transferring hay alongside sowing seeds did not alter the cover of target grass and forb species.

Sixteen studies were in the USA, two were Global and one was in each of Italy, the Seychelles, Madagascar, Cameroon, Egypt, China, Jordan and France. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (24 STUDIES) Abundance (4 studies): One replicated study and one of two global reviews reported that three of eight translocations of turtles resulted in established populations and 15 of 47 reptile translocations resulted in stable or growing populations (review included both wild-caught and captive bred animals). The other review (both wild-caught and captive bred animals) reported that one of five translocation of tortoises and snapping turtles was unsuccessful and four had unknown outcomes. One study in the Seychelles found that 47% of translocated Aldabra giant tortoises were found 12 years after releaser. Reproductive success (5 studies): One global review reported that successful reproduction was found in three of five translocations of tortoises and snapping turtles (review included both wild-caught and captive bred animals). Two of three studies (including one replicated, randomized study) in the USA, Italy and Madagascar reported successful reproduction in translocated populations of gopher tortoises and radiated tortoises. The other study reported no evidence of reproduction for three years following a translocation of European pond turtles. One replicated study in the USA found that translocated female Agassiz’s desert tortoises bred successfully following release, but all hatchlings were sired by resident tortoises, not translocated males. Survival (16 studies): Two of four controlled studies (including one replicated study) in the USA found that translocated eastern box turtles and Eastern painted turtles had lower survival than resident turtles. The other two studies found that translocated desert tortoises and musk turtles had similar survival to that of resident turtles. One replicated study in the USA found that translocated gopher tortoises released into temporary enclosures had similar survival compared to head-started tortoises also released into temporary enclosures over four years. Five of 11 studies (including two replicated, controlled studies) in the USA, Italy, Cameroon, Egypt, China, Jordan and France reported that 69–100% of 3–40 translocated individuals survived for monitoring periods of one month to two years. Four studies reported that 19–43% of 15–109 translocated individuals survived for 2–3 years. The other two studies reported that 0–1% of 15 and 249 translocated individuals survived for up to a year. Condition (3 studies): One controlled study in the USA found that translocated Eastern painted turtles lost more body mass than resident turtles. One controlled, before-and-after, replicated study in the USA found that translocated desert tortoises had similar stress levels compared to resident tortoises. One study in the USA found that one translocated Blanding’s turtle grew over a two-year period following release. BEHAVIOUR (9 STUDIES) Use (2 studies): Two replicated studies (including one controlled study) in the USA found that one of 13 translocated gopher tortoises returned to its point of capture, and no Agassiz’s desert tortoises translocated >5 km returned to their point of capture. Behaviour change (7 studies): Two of six studies (including three replicated, controlled studies) in the USA and Jordan found mixed effects on the movement of translocated red-eared slider turtles in spring or autumn and on the movement and home range size of translocated eastern box turtles compared to residents. Two studies found that four measures of behaviour of translocated musk turtles and home range size of translocated spur-thighed tortoises were similar to residents. One study found that translocated gopher tortoises moved more and had larger home ranges than resident tortoises. The other study found that after ephemeral ponds dried up, translocated Eastern painted turtles did not move to new ponds whereas resident turtles did. One replicated study in France found that the home ranges of translocated European pond turtles were smaller in the year after release compared to the year they were released.

Seven studies were in the USA, two were in Antigua, two were global and one was in each of Canada, South Korea and Australia. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (12 STUDIES) Abundance (6 studies): One of two global reviews reported that 15 of 47 reptile translocations (number of snake species not provided) resulted in stable or growing populations (both wild-caught and captive bred reptiles or snakes). The other review reported that the outcome of one indigo snake reintroduction was unknown. One replicated study in the USA found that five of 13 translocations of snakes resulted in established populations. Three studies in Canada and Antigua reported that 3–7 years after translocations of red-sided garter snakes and Antiguan racer snakes, greater numbers were counted. Reproductive success (3 studies): One global review reported that breeding occurred in nine of 22 reptile translocations (of both wild-caught and captive bred animals). Two studies in Antigua reported successful reproduction in translocated populations of Antiguan racer snakes three years after release. Survival (8 studies): Three controlled studies in the USA and Australia found that translocated timber rattlesnakes, northern water snakes and dugite snakes had lower survival than resident snakes, and in one study no translocated snakes survived a year. One controlled study in the USA found that ratsnakes held in captivity for 1–7 years before release had lower survival compared to snakes held for 7–18 days or resident snakes. Four studies (including one replicated, controlled study) in Canada, the USA and South Korea reported that 12–45% of snakes survived for three months to eight years after release. Condition (1 study): One controlled study in the USA found that translocated northern water snakes had similar growth rates compared to resident snakes. BEHAVIOUR (5 STUDIES) Behaviour change (5 studies): Three of five controlled studies in the USA found that differences in movement and home range size of translocated and resident hognose snakes, ratsnakes and dugite snakes were mixed. The other two studies found that translocated timber rattlesnakes and northern water snakes had larger home ranges than residents. One study also found that translocated timber rattlesnakes had higher daily movements than resident snakes.

The other review reported that populations from eight of 13 iguana translocations survived for at least 5–20 years. Two of six studies (include one site comparison study) in St. Lucia, the Bahamas and New Zealand reported that translocated lizard populations increased over 3–10 years. Two studies reported that translocated populations remained stable for one and 6–12 years. One study reported that a translocated population declined over 1–2 years. The other study reported that a translocated population of iguanas survived for at least 40 years. Reproductive success (5 studies): Two reviews that were global and in New Zealand reported that breeding occurred in 20% and at least 30% of lizard translocations (both wild-caught and captive bred animals). Three studies (including one replicated study) in New Zealand, Turks and Caicos Islands and the Bahamas reported successful reproduction in a translocated Whitaker’s skink population, a Turks and Caicos Rock Iguana population and one of two San Salvador rock iguana populations after 14 months to five years. Survival (10 studies): Seven of eight studies (including one replicated, controlled study) in New Zealand, Turks and Caicos Islands, Australia, the Bahamas and Anguilla found that 40–85% of translocated lizards survived for at least 3 months to seven years or that no mortality was reported in the first year after release. The other study reported that at least one lesser Antillean iguana survived for at least two years. One review in New Zealand found that 9% of lizard translocations (both wild-caught and captive-bred animals) resulted in complete failure (no individuals survived). One site comparison study in New Zealand found that 1–2 years after a translocation of shore skinks, individuals representing three of four pattern types originally released still survived. Condition (1 study): One replicated, controlled study in Australia found that 67% of Napoleon’s skinks gained weight following release. BEHAVIOUR (2 STUDIES) Use (1 study): One replicated, controlled study in Australia found that all six Napoleon’s skinks translocated to restored mining sites moved into unmined forest within a week of release. Behaviour change (1 study): One replicated, before-and-after, controlled study in Australia found that provision of artificial burrows and supplementary food affected the use of bare ground areas by pygmy blue tongue lizard translocated into enclosures.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F3719https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F3719Mon, 13 Dec 2021 15:36:46 +0000Collected Evidence: Collected Evidence: Translocate adult or juvenile reptiles: Crocodilians Two studies evaluated the effects of translocating crocodilians on their populations.
