“…Similarly to abundance, at the largest scale of the investigation, at 2 km, the extent of arable fields (including organic fields) had negative effect. This is in agreement with the findings of Pywell et al (2006), that the richness of the bumblebee assemblage at a 10 × 10 km square scale was positively correlated with land use heterogeneity and the proportion of grasslands.…”

“…We suggest integrating the following general practices into management plans: (i) increase nesting opportunities with the particular nesting needs of different pollinating species in mind and these may include gaps in surface vegetation or modifying cultivation practices (Shuler et al 2005), retaining neighbouring forest nesting sites for groundnesting bees (Cane 1997a,b) or leaving dead wood providing holes for cavity-nesting bees (Westrich 1996), (ii) increase forage by providing suitable diverse floral resources in the local area and the broader landscape during the season of pollinator activity (Kevan et al 1990;Banaszak 1992;Westrich 1996;Goulson 2003;Ghazoul 2006). Crop rotation using these flowering plants should be especially applied in intensified uniform agricultural landscapes and may also help to enhance other ecosystem services such as soil improvement, pest management by breaking cycles of damaging pests or erosion control, (iii) enhance opportunities for colonization by connecting habitats with flowering strips and hedgerows around arable fields, small forest patches or even single trees as 'stepping stones' (Steffan-Dewenter et al 2002Pywell et al 2006), and (iv) reduce the risk of population crashes in the field and the surrounding habitats by foregoing use of broad-spectrum insecticides during bloom, especially those with systemic or micro-encapsulated formulations that can contaminate nectar and pollen (Kevan 1975;Wood 1979;Delaplane & Mayer 2000). Financial burdens of these recommendations could be ameliorated through agro-environmental schemes, such as those in Europe and the United States, which compensate farmers who apply management strategies to conserve biodiversity.…”

“…These studies have identified several factors that can affect abundance and species diversity in the strips: flower abundance (e.g. Pywell et al, 2006), plant diversity (e.g. Aviron et al, 2007) seed mixture (e.g.…”

“…Species groups that have been studied include bees and bumblebees, butterflies, beetles, bugs, grasshoppers. Sown wildflower strips have proven capable of containing high numbers of bumblebees (Carvell et al, 2006(Carvell et al, , 2007Pywell et al, 2005Pywell et al, , 2006, with strips sown with few plant species particularly rich in pollen and nectar attracting most bumblebees (e.g. Pywell et al, 2005).…”
