Abstract: A survey of the Boston Harbor Islands national park area yielded 175 lichen species in 67 genera, and 70 bryophyte species in 44 genera. Ten percent of the lichens represent a maritime floristic element, and four percent represent a Coastal Plain element. Caloplaca verruculifera, an orange lichen of rocky shores, is reported new to Massachusetts. Human disturbance and air pollution seem to be the major limiting factors to colonization by lichens and bryophytes on the islands, and specific recommendations for protecting sensitive lichen and bryophyte communities are presented.
Notes: Ray Abair (bryophytes) assisted in the initial phase of this project. This online checklist was put together by Scott LaGreca; all vouchers were linked by Scott LaGreca. The other BOHA lists on CNALH were not assembled by me.
