Terrestrial restoration ecology is not as well developed as aquatic and wetland restoration. There are several key obstacles to progress in restoration ecology, but these obstacles may also be viewed as opportunities to exploit. One obstacle is demonstration science, or an overreliance on simplistic experiments with few treatment factors and few levels of those factors. Complex, multivariate experiments yield greater insights, especially when teamed with sophisticated methods of data analysis. A second key obstacle is myopic scholarship that has led to little synthesis and weak conceptual theory. A greater awareness of and explicit references to ecological principles will help develop the conceptual basis of restoration science. Where should restoration ecology be headed? We should consider forming partnerships with developers, landscape artists, and industry to do complex, large-scale experiments and make restoration a more common part of everyday life.
