In central New south wales, Australia, £owers of Acacia brachybotrya and Eremophila glabra plants growing in linear vegetation remnants received less pollen than conspeci¢cs in nearby reserves. Pollen supplementation increased fruit production by both species, indicating pollen limitation of fruit set. Together these observations explain why fruit production by these species was depressed in linear-strip populations relative to nearby reserves. This study con¢rms that habitat fragmentation can lead to a decline in pollination and subsequent fruit set in wild plant populations. Disrupted pollination interactions of the kind documented in this study may o¡er a substantial challenge to the conservation of biodiversity in fragmented landscapes.
