April 16, 2005: Lucas County
Jim Toppin and Janet Traub were hosts for the spring foray. A small gathering of 8 or 9 met at Lou Campbell State Nature Preserve for a one-day field trip that also included a visit to the limestone outcroppings along the Maumee River.
The next foray is scheduled for Lawrence County, October 1-2, 2005.

Lucas County is located in glaciated northwestern Ohio with Toledo the largest city and the county seat. On Saturday, April 6, 2005, a small group of dedicated bryologists and lichenologists met for a one-day field exploration of the local moss and lichen flora. The following 2 sites were the main areas of study.

I. Lou Campbell State Nature Preserve, approximately 41°35’ N; 83°45’ W in Springfield Township, covers 170 acres and includes a mosaic of black oak savannas, wet sedge meadows, swamp and oak woodlands. sand dunes and sand barren prairies.

2. Metroparks Toledo Area: Farnsworth Metropark, Roche de Boeuf is located approximately 41°28’ N; 83°43’ W in Waterville Township, and runs along the western shore of the Maumee River. Rising sharply from the narrow river floodplain, limestone outcrops form both talus slopes and cliffs 20-30 feet in height. The shallow river and narrow floodplain in the immediate area is littered with glacial cobbles and limestone rocks.

The following list of lichen and moss species is arranged alphabetically by site. The names used are those preferred by the collector and identifications are those of the collectors, rather than of the authority on one individual.

The Lichens
Both lichen biomass and diversity were quite low in the areas sampled. Although a total of 28 species was recorded, several of these were in depauperate condition (Flavoparmelia caperata, Parmelia sulcata, Punctelia rudecta) or of underdeveloped size (Myelochroa aurulenta, Phaeophyscia adiastola, Phaeophyscia cernohorskyi, Phaeophyscia rubropulchra, Physciella chloantha). The only species considered common were those known to be pollution tolerant and especially nitrophilous (Candelaria concolor, Physcia millegrana, Physcia stellaris, Xanthomendoza sp.) These species are able to survive, not only in spite of, but because of nitrogen pollution due to the close proximity of the Ohio Turnpike and Toledo Express Airport (to the Lou Campbell State Nature Preserve). The only soil lichen considered common in the sand barrens was Cladonia polycarpoides, much of it consisting of sterile squamules only. In addition, the genus Caloplaca was considered common on the limestone rocks at Roche de Boeuf.

The rocky shoreline and much of the narrow river floodplain of the Maumee River were recently inundated with floodwaters and rocks were presently covered with mud and debris. As a result, any lichens once growing on these rocks (if any) were completely obscured.
