“…The FQA accounts for the presence of both native and exotic species, as well as individual plant species' tolerance of and sensitivity to disturbance (Cronk andFennessy 2001, Miller andWardrop 2006). We assigned coefficients of conservatism (C-values) to all plant species recorded and identified to species (Northern Great Plains Floristic Quality Assessment Panel 2001, Jones 2005, Rocchio 2007. C-values represent the relative tolerance of a species to disturbance, ranging from 0 to 10.…”

“…Although most commonly used in stream ecosystems, the IBI approach has been extended to wetlands (e.g. Fennessy et al 2001), riparian vegetation (Rothrock et al 2008;Ferreira et al 2005;Jones 2005), lake vegetation (Fore 2005;Nichols et al 2000) and terrestrial ecosystems (Kimberling et al 2001). Of the published wetland IBIs, most have been developed for emergent or shrub dominated wetland systems (Hargiss et al 2008;Rocchio 2007;Genet and Bourdaghs 2006;Rothrock and Simon 2006;Hargiss 2005;Jones 2004;Grabas and Pernanen 2004;DeKeyser et al, 2003a, b;Lane 2003;Lane et al 2003;Gernes and Helgen 2002;Lillie et al 2002;Simon et al 2001;Carlisle et al 1999;Gernes and Helgen 1999).…”

Most plant-based indices of biotic integrity (IBIs) developed for wetlands have focused on emergent wetlands. A Vegetation Index of Biotic Integrity (VIBIForest) was developed for forested wetlands in the four large ecoregions of the Ohio. Assessing the effect of human disturbance on the ecological condition of wetland forests is complicated by several factors. First, forest canopies can remain largely intact even after significant degradation of the herb and shrub stratum. Second, increases in total diversity may not be good. In forested wetlands, a major artifact of disturbance is the addition of non-wetland or wetland native or adventive plant species adapted to full sun conditions to their floras. Initial versions of the VIBI-Forest metrics were very sensitive to disturbance-induced increases in diversity. Correcting this problem required modifying or replacing metrics so that only forest dependent species were included in metric calculations. The final VIBI-Forest included metrics which evaluated each forest stratum including the ground layer (% bryophyte), herb layer (shade or seed-less vascular plant species), shrub layer (subcanopy importance value (IV), relative density of young trees), canopy (canopy IV), and composite metrics for all vertical strata (Floristic Quality Assessment Index score, % hydrophytes, % sensitive, % tolerant). Assessing wetland forest condition is further complicated by the fact that some successional communities after canopy death or destruction (shrub swamp, marsh, wet meadow) may have intrinsic value as wetland community types. The solution is not to attempt to derive a one-size-fits-all assessment method but to derive separate protocols for other successional phases that are of value or interest.
