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”

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.

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.
