Evaluating Dispersal Limitation in Passive Bottomland Forest Restoration

Battaglia, L. L., Pritchett, D. W., and Minchin, P. R. Restoration Ecology 16 (3):417-424. 2008.

Dispersal limitation can retard natural establishment of desirable species on restoration sites, especially where landscapes are fragmented, but dispersal limitation is assumed to become less critical with time as early colonists become reproductively mature. Distribution patterns of recruiting trees in a 20-year-old passively restored bottomland in northeast Louisiana suggested persistent dispersal limitation in some bottomland hardwood species and influence of dense shrub patches on colonization. To test these hypotheses, we measured seed rain as a function of distance to seed source and association with shrub cover.
