Variable General Info
Floral richness ?Comment:Floral richness and abundance were estimated along five parallel 100‐m‐long transects within each 1‐ha plot separated by 10–15 m (Figure 1c). All blooming flowers encountered within 1 m of either side of the transect were identified to species and counted. |

|
Not reported ?Comment:Bee resources (i.e. Soil PC1, floral richness, FQI and floral abundance) as well as bee abundance and richness were analysed with generalised least squares (GLS). Soil PC1, Log (floral abundance) and Management were the most predictive variables for Floral richness. |
