Governmental agri-environment schemes (AES) aim to improve pollinator abundance and diversity on farmland by sowing wildflower seed mixes. These often contain high proportions of Fabaceae, particularly Trifolium (clovers), which are attractive to some bumblebee species, but not to most of the ~ 240 solitary bee species in the UK. Here we identify wildflowers that are attractive to a greater range of wild bee species. Forty-five wildflower species being farmed for commercial seed production on a single farm were surveyed for native bees. Bee walks were conducted through discrete wildflower areas from April until August in 2018. The results indicate that including a range of Apiaceae, Asteraceae, and Geraniaceae in seed mixes would cater for a wide diversity of bee species. A total of 14 wildflower species across nine families attracted 37 out of the 40 bee species recorded on the farm, and accounted for 99.7% of all visitations. Only two of these 14 species are included in current AES pollinator mixes. Unexpectedly, few visits were made by bumblebees to Trifolium spp. (0.5%), despite their being considered an important food source for bumblebees, while Anthyllis vulneraria and Geranium pratense were highly attractive. For solitary bees, Crepis capillaris, Sinapsis arvensis, Convolvulus arvensis and Chaerophyllum temulum were amongst the best performing species, none of which are usually included in sown flower mixes. We suggest that the standard 'pollinator' mixes used in AES might be updated to include some of these wildflower species, and trialled as seed mixes on farmland.

Purpose: Alternative sentencing programs for women with nonviolent drug offenses may provide opportunities to change the life trajectories of women and their families. The primary purpose of this study was to assess whether a mindfulness-based stress reduction (MBSR) intervention could improve levels of hope following treatment. A second objective was to assess whether MBSR intervention could influence perceived stress, self-compassion, and mindfulness. Methods: Participants attended a 6-week mindfulness class, with outcomes measured using pretest–posttest survey comparison. Results: Paired sample t tests showed improvements in hope, stress, self-compassion, and mindfulness following treatment. Discussion: Community-based intervention models, such as MBSR therapy in alternative sentencing programs, may alleviate negative psychological impacts experienced by female offenders. These results align with previous research that suggests participants may see improved ability to regulate emotions following MBSR therapy. This research indicates that MBSR therapy, for women in alternative sentencing programs, may promote hope as a learned psychological skill.
