Zedler, J.B. 2006. How hydrologic manipulations can accelerate cattail invasions via "internal eutrophication". Arboretum Leaflet 7

It is possible that simply prolonging the period of standing water (as behind dams) stimulates enough release of phosphorus by soil to accelerate cattail invasions. This new scenario for wetland plant invasions is called "internal eutrophication."

Zedler, J.B. Kercher, S.K. and A. Herr-Turoff. What accelerates reed canary grass invasions? 2005. Arboretum Leaflet 5

Results from a two-year experiment, with reed canary grass subjected to 27 treatments, showing strong interactions among flooding and nutrient loading and rapid shifts from diverse wet prairie to rcg monotypes.

Zedler, J. B. Adaptive restoration. 2005. Arboretum Leaflet 4

An explanation of "learning while restoring," an approach wherein restoration is undertaken as experiments, with each phase learning from earlier experiments and addressing new hypotheses about how best to restore degraded sites.

Zedler, J.B. and C. Frieswyk. 2005. Characterizing dominance: Which species are dominant and how do they dominate? Arboretum Leaflet 3

A discussion of what "dominance" means relative to plant species. Proposes a "species dominance index" which takes into account mean cover as well as suppression of other species.
