“…On the contrary, Goulson et al (2002) found that, although A. mellifera presence was negatively correlated to wild bee presence, there was no correlation between the presence of B. terrestris and the abundance and richness of native pollinators. Similarly, Nishikawa and Shimamura (2016) and Nagamitsu et al (2007) did not detect negative competitive effects between B. terrestris and local bumblebee species despite apparent resource overlaps.…”

“…Such observational evidence was not conclusive because factors confounded with honey bee abundance, such as habitat disturbance, could cause declines in the native bee abundance (Butz Huryn 1997). On the other hand, there was no clear reduction in the diversity and abundance of native bees in periods when or in sites where exotic social bees had colonized (Roubik and Wolda 2001;Goulson et al 2002). These findings, however, are not sufficient evidence for the absence of competition because the confounding factors are not discriminated from competitive effects.…”

“…However, our study also implies that an alternative to the removal of foundresses is required to control feral B. terrestris populations that have expanded their distribution. As a target of the removal, colonies before males and gynes are produced seem to be the most vulnerable because the density of reproductive units is the lowest in their life cycle (Goulson 2003b). In addition, the influence of immigration can be ignored because colonies are sessile.…”

A commercialized bumble bee pollinator (Bombus terrestris) introduced from Europe has colonized in Japan and potentially competes with native bumble bees for food and nest sites. To examine the competitive impacts, a field removal experiment was conducted in an area in northern Japan where B. terrestris has become feral. In 2005 and 2006, totals of 1,511 and 2,978 B. terrestris bees, respectively, were killed in six removal sites. In those 2 years and the pre-removal year (2004), the bee abundance and worker body size were measured in the six removal sites and seven control sites, and effects of the removal on the measurements were examined using statistical models. In 2005 only, the removal decreased the number of B. terrestris queens and increased that of two native species, B. ardens and B. hypocrita, the tongue length of which overlaps that of B. terrestris. The removal in 2005 affected the worker body size of neither B. terrestris nor any native species. These results show the competitive impacts of exotic B. terrestris on the queen abundance of the native species that are likely to share floral resources with B. terrestris.

“…Thus, the first tool to preserve of these favorable habitats can be achieved by the establishment of protected areas via legal measures to prevent additional alterations, as well as the purchase of ecological valuable areas. In these protected areas, adaptive management of both pollinators and ecosystems have to be set up by testing assumptions to define the best strategies and adapting the measures consequently to empirical evidence of the successes and failures of the management measures [79][80][81]. However, many anthropogenic habitats (e.g., cities) cannot have the same amount of protection than semi-natural areas, but yet require conservation measures.…”

Wild bees are facing a global decline mostly induced by numerous human factors for the last decades. In parallel, public interest for their conservation increased considerably, namely through numerous scientific studies relayed in the media. In spite of this broad interest, a lack of knowledge and understanding of the subject is blatant and reveals a gap between awareness and understanding. While their decline is extensively studied, information on conservation measures is often scattered in the literature. We are now beyond the precautionary principle and experts are calling for effective actions to promote wild bee diversity and the enhancement of environment quality. In this review, we draw a general and up-to-date assessment of the conservation methods, as well as their efficiency and the current projects that try to fill the gaps and optimize the conservation measures. Targeting bees, we focused our attention on (i) the protection and restoration of wild bee habitats, (ii) the conservation measures in anthropogenic habitats, (iii) the implementation of human made tools, (iv) how to deal with invasive alien species, and finally (v) how to communicate efficiently and accurately. This review can be considered as a needed catalyst to implement concrete and qualitative conversation actions for bees.
