DescriptionRestorations require diverse communities of non-target organisms for important ecosystem functions and meeting restoration goals, yet little is known about how communities of non-target organisms such as wild bees develop over time. We sampled bee communities along a 26 year chronosequence of restored tallgrass prairie in north-central Illinois to evaluate whether bee abundance, richness, and community composition in restored habitat converges on that of remnant prairie, and to study the processes that shape community development over time. Restoration increased bee abundance and richness from the low level of the pre-restoration (agricultural) sites to the target level of the remnant prairie within the first 2-3 years after restoration, and maintained high abundance and richness throughout the entire restoration chronosequence. Bee richness peaked at the oldest restored sites of 22-26 yrs, in which it surpassed that of even prairie remnants. Bee community composition of the youngest restored sites differed from that of remnants in terms of relative species abundances, but the community composition of prairie restorations converged on remnants by 5-7 years after restoration. Changes in community composition of restorations over the chronosequence progressed predominantly through the gradual accumulation of species, rather than species replacement. We conclude that tallgrass prairie restoration is successful in restoring bee communities when examined over long timeframes.
