Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Use electric fencing to exclude fish-eating birdsTwo before-and-after studies from the USA found that electric fencing reduced the use of fish ponds by great blue herons Ardea herodias and great egrets Casmerodius albus. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F247https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F247Wed, 18 Jul 2012 11:52:28 +0100Collected Evidence: Collected Evidence: Use education programmes and local engagement to help reduce persecution or exploitation of species Five out of six studies from across the world found increases in bird populations or decreases in mortality following education programmes. In all but one case, education was one of several interventions employed. A replicated before-and-after study from Canada also found that there was a significant shift in local peoples’ attitudes to conservation and exploited species following educational programmes. One study from Venezuela found no evidence for decreases in yellow-shouldered parrot Amazona barbadensis poaching following an educational programme in local schools. The authors argue that the benefits would probably be seen later in the project.

Six of the studies used several interventions at once. Two studies from the USA found that least terns Sterna antillarum and herons were not attracted to new areas to breed when decoys were used. Five studies from North America and France and Spain found that more birds landed near decoys than in control areas. The two studies to compare decoy types found that three-dimensional models were better than two-dimensional ‘cut-outs’ and plastic models of birds were better than rag decoys.

One replicated, randomized, controlled study in the USA did not find an increase in the number of shrub species, but one controlled study in China did find an increase in plant diversity following the use of erosion control blankets. The same study found an increase in plant biomass and cover.

Three studies were in the USA, two were in Spain, one was in Germany and one was in Croatia. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (7 STUDIES) Survival (1 study): A randomized, replicated, controlled study the USA found that medical treatment of Rocky Mountain bighorn sheep against lungworm did not increase lamb survival. Condition (6 studies): Three of four before-and-after studies (one controlled), in Germany, the USA and Croatia, found that after administering drugs to mammals, parasite burdens were reduced in roe deer and in wild boar piglets and numbers of white-tailed deer infected were reduced. A third study found that levels of lungworm larvae in bighorn sheep faeces were reduced one month after drug treatment but not after three to seven months. One of these studies also found that the drug treatment resulted in increased body weight in roe deer fawns. A replicated, controlled, before-and-after study in Spain found that higher doses of ivermectin treated sarcoptic mange in Spanish ibex faster than lower doses, and treatment was more effective in animals with less severe infections. A replicated, before-and-after study in Spain found that after injecting Spanish ibex with ivermectin to treat sarcoptic mange a mange-free herd was established.

Two studies were in the USA and one study was in Spain. VEGETATION COMMUNITY (1 STUDY) Overall richness/diversity (1 study): One replicated, randomized, controlled study in Spain found that using an organic blanket after sowing seeds increased plant species richness. VEGETATION ABUNDANCE (3 STUDIES) Overall abundance (3 studies): Two of three replicated, controlled studies (two of which were paired and two randomized) in the USA and Spain found that using an erosion blanket after seeding and planting did not alter vegetation cover. The other study found that using an organic blanket after sowing seeds increased plant density.

Three studies were on open coastlines in the UK and Ireland, and one was in each of an estuary in southeast Australia, a marina in northern Israel, and a port in southeast Spain. One was on an open coastline and in estuaries in the UK, and one was on island coastlines in the Singapore Strait and in estuaries in the UK. COMMUNITY RESPONSE (6 STUDIES) Overall community composition (4 studies): Two of four replicated, controlled studies (including three randomized and one paired sites, before-and-after study) in Australia, the UK, Israel, and Singapore and the UK, found that using hemp-concrete in place of standard-concrete on intertidal artificial structures, or using ECOncreteTM, along with creating grooves, small ledges and holes, altered the combined macroalgae and invertebrate community composition on structure surfaces. One of the studies, along with one other, found that using shell-concrete or reduced-pH-concrete did not. One study found that using sandstone in place of basalt had mixed effects, depending on the site. Two of the studies reported that ECOncreteTM surfaces with added habitats or reduced-pH-concrete surfaces supported macroalgae, mobile invertebrate and/or non-mobile invertebrate species that were absent from standard-concrete structure surfaces. Algal community composition (1 study): One replicated, randomized, paired sites, controlled study in Spain found that using different materials (sandstone, limestone, slate, gabbro, concrete) on an intertidal artificial structure altered the diatom community composition on structure surfaces. Overall richness/diversity (4 studies): Two of four replicated, controlled studies (including three randomized and one paired sites, before-and-after study) in the UK, Israel, and Singapore and the UK found that using hemp-concrete, shell-concrete or reduced-pH-concrete in place of standard-concrete on intertidal artificial structures did not increase the combined macroalgae and invertebrate species richness on structure surfaces. One study found that using ECOncreteTM, along with creating grooves, small ledges and holes, did increase the species richness and diversity. One found that using limestone-cement, along with creating pits, grooves, small ridges and texture, had mixed effects depending on the site. Algal richness/diversity (1 study): One replicated, randomized, paired sites, controlled study in Spain found that using quarried rock in place of concrete on an intertidal artificial structure did not increase the diatom species richness or diversity on structure surfaces. Invertebrate richness/diversity (1 study): One replicated, randomized, controlled study in the UK found that using hemp-concrete in place of standard-concrete on intertidal artificial structures increased the mobile invertebrate species richness on structure surfaces, but using shell-concrete did not. POPULATION RESPONSE (7 STUDIES) Overall abundance (1 study): One replicated, randomized, controlled study in the UK found that using hemp-concrete or shell-concrete in place of standard-concrete on intertidal artificial structures increased the combined macroalgae and non-mobile invertebrate abundance on structure surfaces. Algal abundance (5 studies): Four of five replicated, controlled studies (including four randomized and one paired sites study) in Australia, Spain, Singapore, the UK and Ireland found that using sandstone in place of basalt, quarried rock in place of concrete, or altering the composition of concrete on intertidal artificial structures had mixed effects on the macroalgal or microalgal abundance on structure surfaces, depending on the species group, site, wave-exposure and/or the type of material tested. One study found no effect of reducing the pH of concrete on macroalgal abundance. Invertebrate abundance (4 studies): Two of four replicated, controlled studies (including three randomized studies) in Australia, the UK, Singapore and the UK and Ireland found that using sandstone in place of basalt or reducing the pH of concrete on intertidal artificial structures did not increase the abundance of tubeworms, oysters, limpets, barnacles and/or combined invertebrates on structure surfaces. Two studies found that using limestone-cement, along with creating pits, grooves, small ridges and texture, or altering the composition of concrete had mixed effects on the mobile invertebrate and/or barnacle abundance, depending on the site, wave-exposure and/or the type of material tested.

Seven studies were on open coastlines in the United Arab Emirates, Italy, Israel, southeast Spain, and in France, the UK, Portugal and Spain. Three were in marinas in northern Israel and the UK, two were in estuaries in southeast Australia and eastern USA, one was in a lagoon in Mayotte, and one was in a port in Germany. COMMUNITY RESPONSE (11 STUDIES) Overall community composition (11 studies): Six of 11 replicated, controlled studies (including eight randomized, three paired sites and one before-and-after study) in Australia, the United Arab Emirates, Italy, Israel, the USA, the UK, Spain and Germany found that using shell-concrete or quarried rock in place of standard-concrete on subtidal artificial structures, or using ECOncreteTM in place of standard-concrete or fibreglass, along with creating texture, grooves, holes, pits and/or small ledges, altered the combined macroalgae and invertebrate community composition on structure surfaces. Three studies found that using quarried rock or blast-furnace-cement-concrete in place of standard-concrete did not alter the community composition, while one found mixed effects depending on the type of rock tested and the site. One found that using different cement mixes in concrete (including some with recycled cements) altered the community composition of native species, but not non-natives. Three of the studies also reported that ECOncreteTM surfaces with added habitats supported mobile invertebrate, non-mobile invertebrate and/or fish species that were absent from standard-concrete or fibreglass structure surfaces. Overall richness/diversity (7 studies): Three of seven replicated, controlled studies (including five randomized, two paired sites and one before-and-after study) in Italy, Israel, the USA, the UK and Spain found that using quarried rock, shell-concrete or recycled-cement-concrete in place of standard-concrete on subtidal artificial structures had mixed effects on the combined macroalgae and invertebrate species richness on structure surfaces, depending on the site, surface orientation or type of cement tested. One of the studies, along with one other, found that using shell-concrete or quarried rock did not increase the species diversity and/or richness, while one found that using recycled cement did not increase the non-native species richness. Three studies found that using ECOncreteTM, along with creating texture, grooves, holes, pits and/or small ledges, did increase the species diversity and/or richness on and around structures. Algal richness/diversity (1 study): One replicated, randomized, controlled study in the UK found that using recycled-cement-concrete in place of standard-concrete on subtidal artificial structures did not increase the diatom species richness on structure surfaces. POPULATION RESPONSE (11 STUDIES) Overall abundance (7 studies): Three of seven replicated studies (including six controlled, four randomized and one paired sites study) in the United Arab Emirates, Italy, Israel, the USA, the UK, Spain, and in France, the UK, Portugal and Spain found that using quarried rock or shell-concrete in place of standard-concrete on subtidal artificial structures did not increase the combined macroalgae and invertebrate abundance on structure surfaces. Two studies found mixed effects, depending on the type of quarried rock or concrete tested and/or the location. One found that using ECOncreteTM in place of fibreglass, along with creating textured surfaces, increased the live cover and biomass, while one found that different ECOncreteTM and standard-concrete mixes supported different cover and inorganic biomass but similar organic biomass. Algal abundance (6 studies): Four of six replicated, controlled studies (including four randomized and one paired sites study) in Australia, the United Arab Emirates, Italy, Israel and the UK found that using quarried rock or recycled-cement-concrete in place of standard-concrete on subtidal artificial structures did not increase the abundance of brown, turf or coralline macroalgae, canopy macroalgae recruits or diatoms on structure surfaces. Two studies found that using quarried rock or using ECOncreteTM, along with creating grooves, holes and pits, had mixed effects on macroalgal abundance, depending on the species group and/or site. One of the studies found that using quarried rock increased red and green macroalgal abundance. Invertebrate abundance (6 studies): Three of six replicated, controlled studies (including four randomized and one paired sites study) in Austalia, the United Arab Emirates, Italy, Israel and the UK found that using quarried rock in place of concrete on subtidal artificial structures, or using ECOncreteTM, along with creating grooves, holes and pits, had mixed effects on the abundance of non-mobile invertebrates, mobile invertebrates or coral recruits on structure surfaces, depending on the type of rock tested, the species group and/or the site. One of the studies, along with one other, found that using quarried rock did not increase the abundance of sponges, bryozoans, ascidians, mussels, barnacles, or Serpulid tubeworms, but in one it decreased Spirorbid tubeworm abundance. One study found that using shell-concrete increased bivalve abundance. One found that different ECOncreteTM and standard-concrete mixes supported different coral abundance. Fish abundance (1 study): One replicated, controlled study in Israel found that using ECOncreteTM in place of standard-concrete on subtidal artificial structures, along with creating grooves, holes and pits, had mixed effects on fish abundances, depending on the species group. BEHAVIOUR (1 STUDY) Use (1 study): One study in Mayotte reported that basalt rock surfaces created on a concrete subtidal artificial structure, along with small and large swimthroughs, were used by juvenile spiny lobsters and groupers, sea firs, and adult fishes from five families.

One study was in each of Costa Rica, India, the Philippines, Dominica, the USA, Saint Kitts and Colombia. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (3 STUDIES) Abundance (1 studies): One before-and-after study in the Philippines found that following a communication, education, and public awareness campaign, the population of Philippine crocodiles increased. Reproductive success (1 study): One study in Costa Rica found that during a community-based education programme the percentage of leatherback turtle nests lost to poaching decreased. Survival (3 studies): Two before-and-after studies in the Philippines and Dominica found that following education and awareness campaigns, one in combination with use of road signs, human killing of Philippine crocodiles decreased and there were fewer road-deaths of lesser Antillean iguanas compared to before the campaigns began. One study in India reported that following education and awareness campaigns in combination with creating a network of local snake experts, local snake experts reported that they intervened to save 276 non-venomous snakes from being killed over six years. BEHAVIOUR (0 STUDIES) OTHER (5 STUDIES) Human behaviour change (3 studies): One replicated study in Colombia found that in areas with conservation initiatives relating to turtles, more people reported changing consumption habitats and fewer people reported using turtles for food compared to in areas with no initiatives, however, stated rates of hunting, buying and selling of turtles remained similar. One study in Saint Kitts found that attending an educational summer camp on turtle conservation had mixed effects on reported behaviours in relation to sea turtles of attendees and their parents/guardians, and mixed effects on whether they took part in conservation activities after the camp. One study in the USA found that providing an information leaflet did not decrease the number of hotel rooms that left lights on at night compared to when no leaflet was provided.
