Buffer zones for biodiversity of plants and arthropods: is there a compromise on width?

Fig. 3.7. Flowering percentages for all plants (a) and dicotyledoneous species (b), for each combination of buffer width (m) and distance (m) from hedge. Within each buffer width, figures with the same capital letter are not significantly different (P≥0.05). Within each distance, figures with the same lower case letter are not significantly different (P≥0.05). Red bars (hatched from lower left to upper right) are percentages in areas treated with fertilizer and pesticides. Green bars (hatched from upper left to lower right) are non-treated area (buffer zone).
