Figure 1. Effects of significant habitat and landscape factors on total pollinator richness and abundance.

Two main factors (patch size and floral abundance) had significant positive effects on both richness (A–C; number of species per 15-min observation period) and abundance (D–F; number of individuals per hour), while one main factor (surrounding percent vegetation) had a significant negative effect. Surrounding percent vegetation at the 650 m radius best described pollinator richness, while the 350 m radius best described pollinator abundance. Each circle represents the mean of one green area (values averaged across all plots within the green area).
