McMullin, R. T. 2012: New and Interesting Lichens from Kejimkujik National Park and National Historic Site, Nova Scotia, Canada. - Opuscula Philolichenum 11: 52-59. [RLL List # 226 / Rec.# 33628]
Abstract: A lichen monitoring program was implemented at Kejimkujik in 2006. At that time, lichens were collected in plots that were established for the monitoring program. These collections were added to all known lichen collections in the park and a provisional lichen list was developed. The monitoring program at Kejimkujik requires an assessment every five years; therefore, the second round of monitoring occurred in 2011. To increase the statistical power of the initial monitoring program six new plots were added to the original six, which led to the discovery of additional lichen species. New records for lichen species previously unreported in the park were also made outside of the study plots. Fifty-three new species were indentified in 2011, which brings the total number of known lichen species in Kejimkujik to 238 in 103 genera. Two of the new lichens discovered are listed by the Committee on the Status of Endangered Wildlife in Canada as species at risk, Erioderma mollissimum (endangered) and Degelia plumbea (special concern). One of the new species discovered is provincially red-ranked (at risk in Nova Scotia), which brings the total number of provincially red-ranked species known in the park to two: E. mollissimum and Xanthoparmelia mougeotii. Three of the new species discovered are provincially yellow-ranked (sensitive to disturbance), which increases the known yellow-ranked species in the park to nine: Anzia colpodes, Cladonia stygia, Leptogium corticola, L. milligranum, L. subtile, Physconia detersa, Sticta fuliginosa, Usnea cavernosa and U. mutabilis.
