Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Translocate mammals that have habituated to humans (e.g. bears) Two studies evaluated the effects of translocating mammals that have habituated to humans. One study was in the USA and one was in the USA and Canada. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (0 STUDIES) BEHAVIOUR (0 STUDIES) OTHER (2 STUDIES) Human-wildlife conflict (2 studies): A study in the USA found that almost half of the translocated ‘nuisance’ black bears returned to their capture locations. A review of studies in the USA and Canada found that black bears translocated away from sites of conflict with humans were less likely to return to their capture site if translocated as younger bears, over greater distances, or across geographic barriers.

Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2483https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2483Thu, 04 Jun 2020 11:42:33 +0100Collected Evidence: Collected Evidence: Introduce nurse plants to aid focal non-woody plants: freshwater wetlands Two studies evaluated the effects, on vegetation, of introducing nurse plants to freshwater wetlands planted with emergent, non-woody plants. Both studies were on the same site in the USA, but used different experimental set-ups. VEGETATION COMMUNITY VEGETATION ABUNDANCE Characteristic plant abundance (1 study): One replicated, randomized, paired, controlled, before-and-after study in an experimental wet basin in the USA found that sowing potential nurse plants alongside target sedge meadow species reduced the density of the target species overall, and of target grass-like species. Nurse plant addition sometimes affected the abundance of target forbs, depending on the presence of an invasive species and addition of sawdust to plots. Individual species abundance (2 studies): Two replicated, randomized, paired, controlled, before-and-after studies in wet basins in the USA quantified the effect of this action on the abundance of individual plant species. One study reported that sowing potential nurse plants typically had no significant effect on – and sometimes reduced – the biomass of sown porcupine sedge Carex hystericina, after 1–2 growing seasons. The other study reported varying effects of potential nurse plants on the abundance of individual target plant species, depending on factors such as diversity of the nurse crop and addition of sawdust to plots. VEGETATION STRUCTURE OTHER Germination/emergence (1 study): One replicated, randomized, paired, controlled study in an experimental wet basin in the USA found that the presence of a high-diversity nurse crop reduced the germination rate of sown sedge meadow species. A low-diversity nurse crop had no significant effect on their germination rate.

Both studies were in the USA. One study was in a laboratory. VEGETATION COMMUNITY VEGETATION ABUNDANCE VEGETATION STRUCTURE OTHER Survival (2 studies): One replicated, controlled study in created wetlands in the USA reported that root-pruned red maple Acer rubrum seedlings had a higher survival rate than unpruned seedlings, 1–2 years after planting. One replicated, randomized, controlled study in a laboratory in the USA found that root-pruned and unpruned Nuttall oak Quercus nuttallii seedlings had similar survival rates, 108 days after planting. Growth (1 study): One replicated, randomized, controlled study in a laboratory in the USA found that root-pruned and unpruned Nuttall oak Quercus nuttallii seedlings grew in height by a similar amount over the first 108 days after planting.

Both studies were in one laboratory in the USA. VEGETATION COMMUNITY VEGETATION ABUNDANCE VEGETATION STRUCTURE OTHER Germination/emergence (2 studies): Two replicated, controlled studies in a laboratory in the USA found that soaking baldcypress Taxodium distichum seeds in weak sodium hydroxide increased their germination rate. One of the studies found that soaking in ethyl alcohol and/or hydrochloric acid reduced the germination rate. One of the studies found that soaking in stronger sodium hydroxide, or hydrogen peroxide and ethyl alcohol, had no significant effect on the germination rate. Growth (1 study): One replicated, controlled study in a laboratory in the USA found that soaking baldcypress Taxodium distichum seeds in chemicals before sowing typically had no significant effect on the height of surviving seedlings, 30 days after germination. Soaking in ethyl alcohol, however, reduced seedling height.

There was one study in each of the UK and Nigeria. VEGETATION COMMUNITY Overall extent (1 study): One replicated, before-and-after, site comparison study in the UK found that paying landowners to manage farmland ditches under agri-environment rules had no clear or significant effect on the frequency of emergent vegetation. Overall richness/diversity (1 study): One replicated, site comparison study in the UK found that farmland ditches managed under agri-environment rules contained a similar number of plant species to ditches not managed under these rules. VEGETATION ABUNDANCE VEGETATION STRUCTURE OTHER Human behaviour (1 study): One study in Nigeria reported that 58 communities with access to micro-credits for sustainable development changed their behaviour. In particular, they switched from livelihood practices that damaged mangrove forests to more sustainable practices.

One study was in Senegal and one was in India. VEGETATION COMMUNITY Overall extent (1 study): One before-and-after study of a coastal wetland in India reported that after implementing a community-based restoration programme, the area of high-quality mangrove forest increased. Meanwhile, the area of degraded mangrove forest decreased. VEGETATION ABUNDANCE VEGETATION STRUCTURE OTHER Human behaviour (1 study): One before-and-after study of a wetland National Park in Senegal reported that after switching from authoritarian protection to community-based management, fewer fines were issued for illegal activities (including illegal settlement and uncontrolled grazing).
