Bryophytes as a Potential Indicator for Wetland Quality Bryophyte Overview Bryophytes as an indicator Bryophytes - NWCA Field Trips Present work Future possibilities http://ohiomosslichen.org/wp-content/uploads/2013/12/Hypn Polytrichum ohioense Tortula truncata MOSSES (Division Bryophyta; 416 species in OH) Eurhynchium hians Bryoandersonia illecebra Bazzania trilobata (a leafy liverwort) Conocephalum conicum (a thallose liverwort) LIVERWORTS (Division Marchantiophyta; 122 species in OH) Nowellia curvifolia (a leafy liverwort) Cephalosia lunulifolia (a leafy liverwort) Hornworts (Division Anthocerotophyta; 3 species in OH) Phaeoceros laevis http://ohiomosslichen.org/wp-content/uploads/2013/12/Plagiomnium-cuspidatum-15-700x466.jpg http://ohiomosslichen.org/wp-content/uploads/2014/11/Hypnum-lindb Why Bryophytes in the OH NWCA? http://ohiomosslichen.org/wp-content/uploads/2013/12/Hypnumcurvifolium-9-700x466.jpg http://wnmu.edu/academic/nspages/gilaflora/c_cribrosus3.jpg Coeffecient of Conservation (CC)– indicates fidelity to a given habitat The Floristic Qualitative Assessment Index (FQAI) - expresses “quality” of given area 𝑭𝑸𝑨𝑰 =∑ (Cci)/√(Nnative) The Floristic Qualitative Assessment Index (FQAI) was renamed the Bryophyte Qualitative Assessment Index (BQAI) since there is no flower in bryophytes! CCs for liverworts and hornworts found in study were estimated since not published before in the “Floristic quality assessment index (FQAI) for vascular plants and mosses for the State of Ohio” http://www.pwconserve.org/graphics/places/merrimacfarm/wetland_040513.jpg http://www.pwconserve.org/graphics/places/merrimacfarm/wetland_040513.jpg Quick Facts • 52 species were found on one site only (that is, 1 site out of 50) • 80 species were found on 5 sites or less. • 9 species were found on 20 or more sites. • Just looking at genera, 35 genera were found on 5 sites or less. • 8 genera were found on 20 or more sites. • Over 100 species and over 60 genera. • Genera are species poor. • Mosses outnumbered liverworts by approximately 6:1 in term of species found.

Ecological Indicators 62:132-146 http://www.epa.ohio.gov/Portals/35 /wetlands/Ohio_Intensification_Final _Report_20151014.pdf Concluding Remarks o Close relationship between the bryophytes and vascular plant community. o Developing an index of biotic integrity for this taxonomic group could be extremely beneficial to the Ohio wetland regulatory program, as most bryophytes are present yearround. o Fewer temporal limitations than our current detailed biological assessments, such as VIBI, VIBI-FQ, and the Amphibian IBI. o Genera count would simplify. o Results strongly suggests that developing an assessment methodology focusing on this taxonomic group is realistic. o Time and resources for continual exploring the potential utility of bryophytes as indicators of wetland quality is limited – depends on interest from wider wetland community.
