J. Stephen Brewer, Christine A. Bertz, Jeffery B. Cannon, Jason D. Chesser, and Erynn E. Maynard. 2012. Do natural disturbances or the forestry practices that follow them convert forests to early-successional communities? Ecological Applications 22:442–458.

Appendix C (TABLE C1). Responses of selected groundcover plants to tornado damage, including only those species that either showed a significant relationship between change in abundance and change in canopy cover (Spearman rank correlation) or that showed a significant post-storm association with canopy cover.
